Filler Metal Calculator
Calculate filler metal weight and quantity needed for butt, fillet, and V-groove weld joints based on dimensions and material.
Fillet welds are triangular (T-joints, lap joints). Butt joints fill a gap between two plates. V-grooves are beveled for thick material.
Total linear inches of weld
Thickness of the base metal — determines leg size for fillets
Wire sizes (0.035, 0.045) are for MIG. Rod sizes (1/16, 3/32, 1/8) are for TIG and stick.
Weld cap height above the surface — typically 1/16" to 1/8"
Gap between base metals — typically 0 to 1/8" depending on joint prep
Leave blank to auto-estimate based on joint type and thickness
