TIG denotes tungsten inert gas; its formal process name is gas tungsten arc welding. Shielding gas protects the molten weld pool while the deposited layer adheres to the substrate.<\/p>\n<p>Independent filler and arc control differentiate the TIG process from a consumable-electrode process. Here, the tungsten provides the arc; filler wire supplies the added metal. Select the welding wire for the stipulated deposit. Weld overlay cladding (or weld cladding) deposits metal for surface protection. The base material bears the load within a qualified material combination.<\/p>\n<p>Terminology is important. In its cladding overview, <a href=\"https:\/\/www.twi-global.com\/what-we-do\/research-and-technology\/technologies\/coating-and-surface-engineering\/cladding\" style=\"color:#242424;text-decoration:underline;\" rel=\"nofollow noopener\" target=\"_blank\">TWI<\/a> addresses surface protection using deposited materials. Corrosion-resistant weld overlay targets the service condition. Hardfacing addresses resistance to wear; building up a worn dimension, and buttering a dissimilar-metal joint have different objectives.<\/p>\n<p><!-- [EXP-SYNTH] --><\/p>\n<p><strong>Enquiry trap:<\/strong> An enquiry trap is when a request for &#8216;cladding&#8217; alone elicits quotes for multiple jobs.

Nickel based, cobalt based and carbide containing materials should be considered from a supported service and welding condition, rather than selected because trade names are recognized.<\/p>\n<p>Inconel 625 is a common nickel-alloy example for corrosive service. For other combinations of wear and corrosion, Stellite-type alloys and cobalt hardfacing may be considered. <a href=\"https:\/\/www.twi-global.com\/what-we-do\/research-and-technology\/technologies\/coating-and-surface-engineering\/cladding\" rel=\"nofollow noopener\" target=\"_blank\">TWI&#8217;s materials overview<\/a> provides some example cases, but doesn&#8217;t permit a substitution of one filler for another.
