welding calculators
Every calculator runs entirely in your browser — nothing you type is sent anywhere.

Fillet Weld Metal Weight Calculator
Estimate the deposited metal weight of an equal-leg fillet weld from the leg size and weld length.

Groove Weld Metal Weight Calculator
Estimate deposited metal weight for a single-V groove (butt) weld from plate thickness, root opening, and angle.

Filler Metal Consumption Calculator
Convert deposited weld weight into the amount of filler wire or electrode you need to buy, by process efficiency.

Weld Heat Input Calculator
Calculate arc heat input per inch and per millimeter from voltage, current, travel speed, and thermal efficiency.

Welding Amperage Guide
A starting-point amperage range for stick (SMAW) or MIG (GMAW) welding, based on material thickness. A setup guide — not a WPS.
All results are an engineering estimate — not for custody transfer. Field measurement and certified tables govern.
