ABOKE Hi-Lo Cost Checker — AWS D1.1 Tolerance & Rework Risk
Enter your current edge mismatch (hi-lo) and wall thickness; the tool checks compliance with AWS D1.1 butt-joint misalignment limits and estimates the rework cost exposure across your section count. Calculator implements the published cost curve from ABOKE’s Pillar guide.
Joint & project specs
Please fill in all fields with valid non-negative numbers.
Measured between two adjacent plates at the joint
AWS D1.1 uses the thinner part for the 10% rule
e.g. 6–12 for a tank, 20–40 for a wind tower
Loaded cost: welder + NDT + bevel rework

Methodology & Standards
Tolerance check based on AWS D1.1:2020 §5.21 butt-joint misalignment provision: offset shall not exceed 10% of the thinner part or 1/8 in. (3 mm), whichever is smaller. Rework hour estimates from the published ABOKE Hi-Lo Cost Curve. Project cost = average rework hours per joint × section count × your loaded rework rate. Actual cost depends on weld procedure, plate material, NDT method, and shop overhead allocation.
