Choosing a welding machine for boiler panel production means purchasing a production sequence, even when the quotation considers it as one machine. The choices related to tube preparation, fin-bar feeding, panel movement and the welding process determine where work starts and ends. The table below separates these choices so that a compact welding station isn’t mistaken for a complete membrane-wall production line.
- Best for standard four-torch SAW panels: Aubrik.
- Best for documented industrial panel-line installations: Pemamek.
- Best for synchronized twin-MIG welding: Technocrats Plasma Systems.
- Best for simultaneous top-and-bottom MAG: Kusakabe.
- Best for welding with handling and finishing: DEUMA.
Disclosure: This guide is published by Aubrik. We list ourselves first because this is our website, not because we claim to be the market leader. The other 19 manufacturers are grouped by what they’re best for, in no particular order within each group.
How We Selected These Manufacturers

Selection required a specific boiler tube-and-fin welding equipment offer, supported by manufacturer product information, company records or attributable supplier listings. Manufacturers and engineering integrators are included across China, India, Türkiye, Finland, South Korea, Japan and Germany. Resellers with no equipment offer of their own, sourcing platforms, directories, boiler-panel fabricators without equipment supply, plastic or PVC membrane welders, and standalone power-source or consumable sellers were excluded. Company information was checked against official websites and public sources in October 2026; four founding years could not be confirmed. The 20 entries represent separate businesses, not 20 independently developed machine designs; cooperation and integration roles remain identified. Aubrik (Wuxi ABK Machinery) is one entry, as is WWTEC / Wise.

Welding Stations and Process-Led Automation

This group starts with the welding task itself: a standard torch arrangement, a named installation, selectable heads, or a station that’s connected to tube handling. The choices overlap, but each supplier offers a different starting point for an engineering discussion.
1. Aubrik: Best for standard four-torch SAW panels
Headquarters: Wuxi, Jiangsu, China; head office and factory. Founded: 1999, according to its About page. Type: Welding equipment and CNC-cutting equipment manufacturer.
Official website: https://aubrikmc.com/
Main products: Standard four-torch and custom six-torch submerged arc welding systems. Published capacity: 1600 mm standard working width; up to 2500 mm for the custom six-torch offer.
Credentials: Aubrik’s website lists ISO 9001 quality management and CE conformity; ISO 9001 concerns the management system.
Aubrik’s membrane panel welding machine offers a clear starting point for shops arranging repeat tube-and-fin work around a standard-width SAW station. The separation between the standard and custom offers helps a buyer frame the width decision before discussing additional torches or adjacent production equipment. Its welding machinery manufacturing background covers welding and cutting equipment, while the panel product page identifies the relevant machine family. Panels wider than the 1600 mm standard therefore belong in a custom-machine discussion, with their dimensions stated at the outset.
2. Pemamek: Best for integrated industrial panel-line installations
Published location: Loimaa, Finland; contact address. Founded: 1970. Type: Designer and manufacturer of welding automation and production systems.
Official website: https://pemamek.com/
Main products: PEMA 3000/6 membrane-wall panel welding line. Process reference: Lincoln Electric AC/DC SAW in the Caldema installation.
Credentials and notable work: The company page links ISO 9001, ISO 14001 and ISO 45001 system certificates; its Caldema case describes a complete industrial installation.
Pemamek gives repeat-production buyers a named reference for assessing how welding and handling fit together in one line. The company’s 2019 Caldema account reports a 35% productivity improvement for that customer’s project, where AC/DC submerged arc equipment replaced an older self-built MIG arrangement. That historical result belongs to Caldema’s installation and gives useful project context, rather than a production promise for a different tube size or factory. A buyer seeking only an individual welding station would be comparing a different purchase from the integrated line described in this reference.
3. Technocrats Plasma Systems: Best for synchronized twin-MIG welding
Published location: Vasai East, Palghar district, India; contact address. Founded: Technocrats began in 1990, became a private limited company in 1994 and a limited company in 2025. Type: Welding and cutting machinery manufacturer offering custom automation.
Official website: https://www.technocratplasma.com/
Main product: Membrane Panel Welding System. Notable capability: The product page describes two synchronized MIG torches welding simultaneously.
Technocrats is a useful starting point when a purchasing team wants to examine a synchronized gas-shielded station rather than begin with a larger SAW head arrangement. The two-torch description identifies a concrete machine feature that can be discussed alongside seam location, tube support and the workpiece feed sequence. The documented twin-MIG arrangement is a different starting specification from a multihead SAW line, so buyers needing the latter should separate those requirements early.
4. Nanjing Qizhi: Best for selectable multihead SAW or MIG lines
Published location: Nanjing, Jiangsu, China; contact address. Founded: 2023, as recorded on the company’s Made-in-China supplier profile, which lists its business type as a trading company. Type: Fabrication-workshop planning and automation-equipment provider.
Official website: https://www.qizhimachine.com/
Main products: SAW and MIG membrane-panel production lines. Notable capability: Six, eight, ten or more heads are offered; the displayed specification lists 1600 mm panel width.
Nanjing Qizhi Engineering & Equipment Co., Ltd. makes head-count choice a visible part of its equipment offer, which helps buyers exploring different seam arrangements. Workshop planning and upgrading are also part of its stated business, placing the panel line within a wider fabrication layout discussion. A larger number of heads can change how the welding task is divided, but the purchaser still needs the actual drawing and active weld positions to compare one offer with another. With a 2023 start and a trading-company registration on its supplier profile, Qizhi is the entry where a buyer most needs to establish which factory builds the line and who commissions it.
5. Primo Automation: Best for boiler-shop welding and tube-handling integration
Published location: Chennai, India; contact address. Founded: 1995 is the company’s stated start of industry service. Type: Designer and manufacturer of welding, handling and steel-fabrication machinery.
Official website: https://www.primoautomation.com/
Main products: Panel welding, tube storage, butt welding, conveyors and benders. Notable work: Its boiler-automation reference names BHEL and ALSTOM Power.
Primo’s attraction is the relationship between the panel welding station and the machines that supply or remove its workpieces. Tube storage, butt welding and conveyors appear alongside the panel equipment, giving an expanding boiler shop several connected production stages to discuss with one machinery manufacturer. The named BHEL and ALSTOM references add a specific boiler-industry context to that equipment portfolio, rather than merely describing general fabrication automation. Primo presents its boiler machines as automation built for named customers rather than catalogue models, so expect an engineered-to-order proposal instead of a standard machine quote.
6. ROBOWEL: Best for project-specific four-head pipe-panel equipment
Published location: Goyang-si, Gyeonggi-do, South Korea; contact address. Founded: 1975. Type: Welding-machine and welding-automation manufacturer.
Official website: http://www.robowel.com/
Main product: Automatic Boiler-Panel Welding Machine. Notable work: Its official project reference identifies a four-head pipe-to-rib machine installed for Samsung Heavy Industries.
ROBOWEL’s project material provides a specific machine and application for a buyer interested in joining boiler tubes to ribs. The four-head description is more useful at the shortlisting stage than an unqualified claim of automation, because the engineering team can relate it to the welds on its own panel drawing. A named customer installation also distinguishes the offer from a general welding-robot catalogue with no stated boiler-panel task. The reference describes a project machine, however, so it doesn’t by itself define a purchased line containing tube preparation, incoming storage, transfer equipment and finished-panel handling.
7. EKO: Best for membrane welding with bar preparation and pressing
Published location: Sincan, Ankara, Türkiye; contact address. Founded: 2014. Type: Welding-machine and automation-system manufacturer with installation and integration services.
Official website: https://ekokaynak.com/
Main products: Membrane welding, bar straightening and membrane pressing machines. Notable capability: Boiler-wall equipment joins pipes and flat bars using automatic positioning and clamping.
EKO’s boiler-specific product category connects the welding task to the condition of the incoming bar and the handling of the finished membrane. That combination suits a buyer whose discussion starts with pipe-to-flat-bar fit-up and extends into straightening or pressing, rather than treating the weld station as an isolated device. According to the company, welding machines and automation systems are produced in its own factory, with installation and integration also offered. A shop seeking a complete tube-preparation line would need a broader package than the welding, bar-straightening and membrane-pressing machines named in this category.
Workshop Expansion and Connected Production Stages

These suppliers are relevant when the purchase extends to preparation, existing-machine integration, bending or cooperative project delivery. Their differences concern the supplied package as much as the welding station.
8. Friendship Machinery: Best for membrane equipment within a wider machinery package
Published location: Wuxi, China; contact address. Founded: 2001, according to its company history. Type: Automatic welding-machinery designer and manufacturer that also represents another Chinese equipment manufacturer.
Official website: https://www.beamweldingline.com/
Main product: Membrane-wall panel production line. Published process: Four submerged-arc welding torches in its supplier-authored listing. Credentials: Company history states ISO9000 quality-system authentication and CE authentication.
Friendship places membrane-wall equipment within its own welding-machine product families, giving the buyer an identifiable panel-production offer inside a mixed machinery business. The four-torch SAW listing is a useful process starting point for a shop comparing conventional multi-torch stations. Its combination of manufacturing and representation also matters when the purchase contains equipment from more than one product family, because the delivery package can include different equipment sources.
9. WWTEC / Wise: Best for preparation, welding and bending in one line plan
Head-office contact: Beijing, China. Founded: Roots in Beijing Lean Welding Technology in 1984; reorganized as Wise in 2000. Type: Welding-plant automation and systems-integration provider.
Official website: http://www.w-wtec.com/
Main products: SAW/MAG panel welders and auxiliary equipment. Notable scope: Preparation, welding, bending, conveyors and storage appear within its panel-line offer.
WWTEC’s equipment scope is useful for a plant that wants to connect panel welding to the next production stage rather than transfer unfinished work through a collection of unrelated stations. Conveyors and storage are especially relevant to that discussion because the weld cycle alone doesn’t describe where work waits or how it reaches bending. The associated purchasing constraint is physical: separate preparation, transport and storage machines must fit the available floor plan as well as the production route.
10. Shanghai Zhengzhuo: Best for 1600 mm welding with matched preparation
Published location: Shanghai, China; contact address. Founded: Business origins in 1996; current entity established in 2005, according to its profile. Type: Boiler membrane-wall and serpentine-tube line developer and manufacturer.
Official website: http://www.shzzzz.cn/
Main product: ZZPPHS/ZZPPHM-1600×4 panel welder, with a published width of 1600 mm. Historical recognition: A March 2023 Songjiang work-safety standardization re-assessment notice named the company for a three-year term.
Zhengzhuo combines a clearly named panel-machine model with a broader boiler-equipment business covering membrane walls and serpentine tubes. Tube and bar preparation can therefore be discussed in the context of the same manufacturing route rather than as an unrelated upstream purchase. The dated 2023 recognition is a historical workplace record, distinct from a current ISO quality-management certificate or certification of a finished panel. For a shop producing wider assemblies, the cited machine’s 1600 mm working width is the immediate constraint that separates this model from a wider-line proposal.
11. SharpTrax: Best for custom MIG equipment integrated with existing machinery
Published location: Thirumudivakkam, Tamil Nadu, India; contact address. Founded: 2005. Type: Provider and integrator of custom-built welding automation.
Official website: https://www.sharptraxtechnologies.in/
Main product: MIG membrane-panel welding machine listed on its IndiaMART supplier page. Published rating: 600 Amp. Notable capability: Integration of custom welding automation with existing machinery.
SharpTrax is a relevant candidate for a factory retaining some of its present equipment and adding a defined welding task around it. The membrane-machine offer is supplier-listed on IndiaMART, while the company’s current website describes the wider custom-automation and integration business. Its only published membrane-panel product is that single 600 Amp MIG machine, so a shop that needs a multi-torch submerged arc line is better served elsewhere on this list.
12. NAGO: Best for waterwall equipment with tube preparation and panel bending
Production location: Shenzhou, Hebei, China; the production address published by Shanghai Nai Geer Technology Development Co., Ltd. Founded: 2014. Type: Designer and manufacturer of boiler membrane-wall and serpentine-tube production equipment.
Official website: http://www.naigeer.com/
Main products: MPM waterwall main machine, ATCP tube-preparation equipment and panel-bending equipment. Notable scope: The catalogue places ATCP preparation alongside the main waterwall machine.
NAGO’s product range makes it useful for examining what happens to the tube before welding and to the panel afterwards. ATCP gives that preparation discussion a named equipment family, while the MPM machine identifies the central waterwall-production task. Panel bending provides a further reason to consider the route as linked stages, especially when the factory wants to reduce transfers between separately purchased machines. NAGO trades under a Shanghai company name but publishes its production address in Shenzhou, Hebei, so factory visits and acceptance tests belong there rather than in Shanghai.
13. Shanghai Haode: Best for MAG membrane-panel lines from preparation through bending
Published location: Putuo, Shanghai, China; registered city and contact address. Founded: Not confirmed. Type: Designer and manufacturer of boiler fabrication equipment, including MAG panel lines.
Official website: https://shdkj.com.cn/
Main product: MAG boiler membrane-wall panel line. Notable scope: Bar finishing and cutting, tube cleaning, welding, joining and panel bending.
Haode’s offer suits a buyer evaluating a gas-shielded panel-production route with preparation and downstream shaping in the same discussion. Strip finishing and tube cleaning identify the upstream tasks, while joining and bending carry the scope beyond an isolated set of welding heads. Weiye’s boiler-sector references explicitly identify cooperation with Shanghai Haode, so those projects were delivered jointly. A shop intending to retain SAW flux circulation and recovery equipment would be comparing a different process package from the MAG line described here.
14. Zhangjiagang Weiye: Best for cooperative boiler-panel automation delivery
Published location: Zhangjiagang, Jiangsu, China; contact address. Founded: Not confirmed. Type: Machinery designer, manufacturer and installer offering MAG membrane-wall production lines.
Official website: http://www.weiyejx.com/
Main products: Boiler-sector membrane-wall automatic welders. Notable work: Boiler references are expressly labelled cooperation with Shanghai Haode.
Published credential: ISO 9001:2015 / GB/T 19001-2016 quality-management certificate for heat-treatment furnaces and welding auxiliary machinery, with printed expiry of 19 November 2026.
Weiye is most useful to shortlist for cooperative projects combining equipment manufacture, installation and commissioning. Its published certificate describes a management-system scope covering heat-treatment furnaces and non-standard mechanical equipment, including welding auxiliary machinery. The buying constraint follows from the cooperation with Haode: manufacturing responsibility, site commissioning and service ownership need distinct assignments within the proposed supply arrangement.
Panel Movement, Two-Sided Welding and Coordinated Controls

This group highlights how the assembly moves through welding and how welding relates to the wider workshop. Solutions to different production problems can be provided by simultaneous welding on both faces, powered feed, automatic dimensional positioning and multi-line coordination.
15. Günısı Enerji: Best for powered tube-and-bar feeding
Production facility: Malatya, Türkiye. Founded: Not confirmed. Type: Industrial energy-equipment manufacturer with a specific membrane-wall welding-machine offer.
Official website: https://www.gunisienerji.com/
Main product: Membrane-wall welding machine with two-, four- or six-head arrangements. Notable capability: Powered rollers move the assembly past stationary heads, with simultaneous welds on both sides of the flat bar.
Günısı’s machine description focuses attention on the relationship between workpiece movement and stationary welding heads. That layout is useful to discuss when the intended factory route depends on feeding assembled tubes and bars through a defined welding position. The company also makes industrial energy equipment, and its machine page carries the same description as Linkweld’s product page, so ask each company who designs, builds and services the machine. In the described operating sequence, torch positioning and the command to start welding remain operator tasks, so powered feeding shouldn’t be read as a fully unattended production cycle.
16. Kusakabe: Best for simultaneous top-and-bottom MAG welding
Location: Toyonaka, Osaka, Japan. Founded: 1966; predecessor business began in 1921. Type: Waterwall tube-panel welding-machine supplier with selectable MAG torch arrangements.
Official website: https://kusakabe-kikai.jp/
Main product: Waterwall Tube Panel Welding Machine, or MPM. Notable capability: Top-and-bottom MAG welding in one pass, without panel turning or flux circulation.
Kusakabe’s distinguishing feature is the published MPM layout, which welds both faces while the panel passes through once. Eliminating panel turnover from that welding sequence changes the handling discussion, while the gas-shielded process removes the flux-circulation equipment associated with the SAW alternative. The company also lists an inverter pulsed MAG power supply, giving the process discussion more detail than the label automatic welding alone. A factory retaining a qualified SAW route would need a separate MAG procedure and consumable plan for this machine, so its handling advantages must be assessed in advance alongside that process change.
17. DEUMA: Best for panel welding with handling and finishing
Operating premises: Central Germany; the company describes its location at regional level. Founded: German company origins in 1939, according to DEUMA’s Chinese affiliate. Type: Manufacturer of complete panel production lines and individual machines.
Official website: https://www.deuma.co/
Main products: Continuous panel welders with two, four or six heads. Notable scope: Calibration, tube-to-tube welding, pipe-end milling, bending and transport systems.
DEUMA offers both a turnkey production-line discussion and an individual-machine purchase, which is valuable when the buyer already owns some upstream equipment. The two-, four- and six-head options describe the welding station, while the preparation and transport products show how that station can sit within a longer route. DEUMA operates through a German parent and a Chinese affiliate, so the quotation should name which entity builds the machines and which one installs and services them.
18. Topweld / Chengdu Hanyan Weida: Best for coordinated boiler-workshop automation
Operating base: Chengdu, China. Founded: 2000. Type: Welding-equipment and smart-workshop developer operating as Chengdu Hanyan Weida.
Official website: http://www.topweld.com/
Main project scope: A jointly developed boiler workshop with header, membrane-wall, drum and serpentine-tube lines. Historical credential: The website displays an ISO 9001:2015 certificate for Chengdu Hanyan Weida with printed validity ending 18 October 2019.
Topweld’s relevant reference connects membrane-wall welding to several other boiler-manufacturing lines within one workshop project. The project was jointly developed with its user, a distinction that matters when describing where the engineering and production experience came from. Header, drum and serpentine-tube operations make this a useful starting point for a factory considering coordinated workshop automation rather than one replacement welding station. A buyer needing only a standard isolated panel welder should recognize that the cited multi-line project describes a substantially wider engineering package, and the displayed certificate is historical rather than current.
19. Linkweld: Best for recipe-controlled membrane-wall integration
Founding location: Istanbul, Türkiye. Founded: 2019. Type: Industrial welding-automation system integrator.
Official website: https://linkweld.com.tr/
Main product: Membrane-wall welding automation with two-, four- or six-head arrangements. Notable capability: Motor-fed operation with stored process settings and selectable head arrangements.
Linkweld belongs in a shortlist that includes engineering integrators because its offer concerns the assembled welding system and the way an operator runs it. The two-, four- and six-head choices give buyers a way to discuss the required weld pattern without assuming every proposal contains the same hardware. Its machine description matches the one on Günısı Enerji’s product page, so ask both companies who designs, builds and services the machine. Its company page describes system integration and presents its own original products as a future goal, so a buyer is dealing with an integrator rather than a machine builder. Manual torch alignment and weld initiation remain in the described sequence, making it a fit for operator-set automation rather than for a shop that requires unattended setup and start.
20. Wastech: Best for automatic positioning from tube and bar dimensions
Factory location: Karatay, Konya, Türkiye. Founded: Not confirmed. Type: Industrial welding-automation equipment producer.
Official website: https://www.wastech.com.tr/
Main product: Membrane welding line. Notable capability: The system takes entered tube and flat-bar dimensions and positions itself automatically, with a moving workpiece and fixed welding heads.
Wastech’s published description is most useful for buyers interested in how a new panel size is translated into machine positioning. Dimension-driven adjustment addresses setup in a different way from simply stating the number of available torches, and it belongs in a discussion of the factory’s product mix. Fixed heads and a moving assembly also identify the basic physical sequence that incoming supports and outgoing handling must accommodate. Because the panel travels in a straight line past fixed heads, ensure the bay has clear run-in and run-out length for the longest panel on both sides of the station.
How to Choose a Membrane Panel Welding Production Line

A short list starts with the panel drawing and ends with the complete production sequence. The number of welding heads, the width of the machine and the name of the process are only parts of that sequence. Following are the seven decisions that allow a production manager, welding engineer and purchasing team to compare proposals on the same basis.
Which companies sell complete membrane-panel welding lines?
Pemamek’s installation reference, DEUMA’s complete-line offer, and the connected equipment ranges of Primo, WWTEC, NAGO and Haode provide starting points for a line-level discussion. Aubrik and Qizhi describe panel-welding choices that also need a defined supply boundary. The word line isn’t enough: the proposal needs to show where incoming material enters and which finished operation leaves the package.
Separate the tube-preparation, flat-bar-preparation and welding operations, as well as the transfer and bending operations on the layout. Identify which of the stations listed are already owned by the buyer, as well as the interfaces the new equipment must satisfy. A panel fabricator selling finished waterwalls serves a different need from a business selling machines. Likewise, a broader welding-equipment manufacturer comparison can help with other shop purchases; however, it doesn’t establish a membrane-line offer for every welding brand.
Specify the panel and tube envelope before choosing head count
Write down the minimum, normal and maximum width and length of the panel, outside diameter of the tube, thickness of the tube wall, width and thickness of a fin-bar, material grade and weight of the assembly to be welded. Include drawings for the parts that account for most production, as well as unusual or awkward cases that define tooling or support. High precision means holding the agreed panel geometry and the weld outcome on the part, not just positioning a torch accurately with no workpiece loaded.
Aubrik lists 1600 mm standard width and up to 2500 mm for its custom six-torch offer. Zhengzhuo’s cited model is specified at 1600 mm, while Qizhi offers different head counts alongside one displayed width. Those are supplier-specific statements, not a universal size limit. The same discipline applies to a steel pipe or tube specification: its outside diameter alone can’t describe the fin fit-up, wall thickness and joint geometry that the station must weld.
When a two-sided MAG layout changes the handling sequence
Kusakabe’s MPM welds the upper and lower faces in one pass without turning the panel. That stated arrangement can remove a turnover operation from the welding route, which changes the required space, supports and movement between stages. Other gas-shielded or submerged arc welding machines have their own layouts; the process abbreviation doesn’t establish how many faces are welded at once.
Compare a sequence drawing for each proposed machine. Show loading, clamping, every welding pass, any turnover, unloading, and downstream work. For SAW, show supplied flux handling; for MAG or MIG, show shielding-gas and torch-service arrangements. Heat input, distortion, and the required weld profile should be included in the process trial for the actual material. Aubrik’s membrane panel welding machine guide explains how to set a process window without treating machine settings as a welding procedure specification. A buyer shouldn’t select a process based solely on a general claim of higher efficiency or lower heat.
Quotation scope and factory/site acceptance checklist
A price is comparable when the quoted delivery has a clearly defined beginning and end. A welding station with feed rollers, a station with tube preparation, and a line with panel bending are different purchases. Label every item as supplied, optional or customer-supplied, and carry the same item list into the acceptance plan.
- Incoming preparation: Tube cleaning or polishing, bar straightening, cutting-machine duties, end preparation, and any removal of oil from the weld surface.
- For welding equipment, check the scope of power sources, wire feeds, torches, fixtures, supporting rollers, cooling, controls, and either shielding gas or flux recovery.
- Movement: Includes loading, transporting, storage, and turning over as required, outgoing supports, connection to panel bending or inspection.
- Control and handover: Includes PLC control scope, recipes, sensor functions, spare parts, machine manuals, commissioning work, and training of operating personnel.
Separate the factory acceptance test (FAT) from the site acceptance test (SAT). The FAT evaluates the agreed upon package against representative work samples. The SAT evaluates the operation of installed equipment with the buyer’s utilities and handling. Neither can be represented by watching the carriage travel at its maximum speed without a load.
Six heads versus four: compare accepted panels per shift
Equipment counts of four and six welding heads don’t equate to production-rate guarantees. Head, torch, wire, seam and panel face describe different things. Determine how many required welds are active together, and which passes remain before the panel is complete. A six-head proposal may still spend time waiting for fit-up, handling or inspection.
Compare accepted panels over the same clock boundary using the same drawing and materials. Include loading, setup, welding, any turnover, unloading, inspection and rework; retain the rejected-panel count along with the completed count. For mixed work, include a size change so that adjustment time is visible. This makes high output a measured result of the proposed system instead of a label based on torch count.
Pemamek’s reported 35% gain concerns the Caldema installation described in its 2019 account and its earlier production route. It’s useful as an attributed project result, but it can’t supply a multiplier for Aubrik, Qizhi or another factory’s schedule.
Installation, service and consumables
Place the proposed equipment on the actual shop layout showing incoming bundles, finished panel access and the space required to change a feed wheel, torch part or support component. Review power, cooling, compressed air where used, process-gas supply and the handling route before settling the delivery boundary. A durable machine requires practical access to wear parts and a defined source for replacements. For SAW that means wire, flux and the parts of the flux-recovery system; for MAG or MIG it means shielding gas, contact tips and liners, and Kusakabe’s MAG layout does away with flux circulation and slag recovery altogether.
For a cooperative project such as Haode/Weiye, identify which party provides site service, commissioning and replacement components for each delivered unit.
Quality records and representative sample panels
Verify certificate holder, scope, date and applicable status once during supplier qualification. ISO 9001 concerns a quality-management system; equipment conformity and finished-boiler acceptance answer different questions. Historical records, such as Topweld’s certificate ending in 2019 or Zhengzhuo’s 2023 workplace recognition, should retain their dates instead of becoming current credentials in a purchase file.
For the product trial, agree material traceability, welding procedure, inspection method and acceptance limits with the responsible fabrication team. Inspect tube and bar condition, fit-up, weld result, and finished panel geometry. Identify any subcontracted special process and its location in the production route. A high-quality sample is useful if the acceptance record describes how the sample was made and inspected, and a sales photo alone isn’t sufficient to demonstrate repeat quality control of the purchased line.
Frequently Asked Questions
Who manufactures membrane panel welding machines?
Aubrik, Pemamek, Kusakabe and DEUMA are among the companies offering equipment for boiler membrane-panel welding.
Can a membrane panel welding machine be customized?
Membrane-panel machines can be offered with custom widths, head arrangements and handling equipment within each supplier’s stated scope.
How much does a membrane panel welding line cost?
A membrane-panel welding line needs a scope-based quotation; the reviewed sources do not establish a comparable installed-price range.
Are membrane panels welded with SAW or MAG?
SAW adds flux feeding and recovery to the station, while the MAG and MIG layouts in this guide run without flux and need shielding gas and torch service instead. Kusakabe’s MAG machine can be designed to weld the top and bottom faces in a single pass, which removes a panel turnover from the route.
Both SAW and MAG appear in the membrane-panel equipment offers reviewed here.
What should a supplier demonstrate before delivery?
A supplier demonstration should show accepted panels produced from the agreed materials and drawing through the purchased sequence.
Is a welding-machine certificate enough for the finished boiler?
A welding-machine certificate does not establish acceptance of the finished boiler.
Discuss Your Boiler Panel Requirements with Aubrik

The best supplier fit follows the panel drawing, welding process and required delivery scope. Send Aubrik the tube and fin dimensions, material, panel size and the preparation or handling stages you need. Discuss your membrane-panel equipment requirements to establish whether the standard four-torch SAW offer or a custom machine belongs on your shortlist. Shops that also need column-and-boom welding equipment or welding positioners for other welds can raise them in the same enquiry, and the separate welding manipulator manufacturer comparison covers that machine’s shortlist.
