Groove Weld Metal Weight Calculator
Estimate deposited metal weight for a single-V groove (butt) weld from plate thickness, root opening, and angle.
How it works
V-groove area ~= root x thickness + thickness^2 x tan(angle / 2). Weight = area x length x 0.284 lb/in^3.
Worked example
1/2 in plate, 1/8 in root, 60 deg, 10 in long: area ~ 0.207 in^2, weight ~ 0.587 lb.
When to use it
- Approximation for a single-V butt joint; add cap reinforcement separately if required.
- Included angle is the total groove angle, not the bevel per side.
