Fillet Weld Metal Weight Calculator
Deposited kilograms for fillet runs — the consumables takeoff.
Weld volume grows with leg SQUARED — an 8 mm fillet deposits 1.8× a 6 mm. Over-welding 'for safety' is the most expensive habit in any fab shop.

Fillet Weld Metal Weight Calculator is a free weld metal weight for welding engineers, fabricators and CWI inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Fillet Weld Metal Weight Calculator
Deposited kilograms for fillet runs — the consumables takeoff. The calculation implements kg/m = (s²/2)×7850×10⁻⁶ × overfill (Lincoln Procedure Handbook — weld metal tables). Weld volume grows with leg SQUARED — an 8 mm fillet deposits 1.8× a 6 mm. Over-welding 'for safety' is the most expensive habit in any fab shop.

Frequently asked questions
What formula does the Fillet Weld Metal Weight Calculator use?+
It computes kg/m = (s²/2)×7850×10⁻⁶ × overfill, per Lincoln Procedure Handbook — weld metal tables. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
Weld volume grows with leg SQUARED — an 8 mm fillet deposits 1.8× a 6 mm. Over-welding 'for safety' is the most expensive habit in any fab shop.
Does this follow AWS/IS welding codes?+
Each tool implements the formula from the cited code or handbook (AWS D1.1, IS 800, ISO/EN). Qualified WPS values always govern over any calculator for code work.
Is the Fillet Weld Metal Weight Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
