Weld Metal Calculator.
Estimate the volume and mass of an equal-leg fillet weld from the leg size, length, density and extra metal.
The section is a right triangle, leg² / 2. It is not a weld procedure, heat input or strength check. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.

An equal-leg fillet has a triangular section of leg² / 2. Mass is that volume times the density and the extra percent for spatter and unused stubs. This is not a weld procedure.
How to use Weld Metal Calculator
Enter the fillet leg and the weld length. Extra metal covers spatter and stub loss and can be zero.
