Welding & Metalwork
Calculators for welders and fabricators: amperage, heat input, weld metal volume, filler and shielding gas use and total weld cost, with the formulas shown.
Shielding Gas Calculator
Calculate MIG and TIG shielding gas used from flow rate and weld time, plus how long a gas cylinder lasts at a given CFH flow rate.
Weld Metal Volume Calculator
Calculate filler weld metal volume and weight for a groove weld from cross section area, length and metal density, in grams and pounds.
Welding Amperage Calculator
Estimate stick (SMAW) welding amperage from electrode diameter using the 1 amp per 0.001 inch rule of thumb, with a practical amp range.
Welding Cost Calculator
Estimate total welding cost from filler metal, labor, gas and power. Add deposition efficiency to size electrode purchased versus deposited.
Welding Heat Input Calculator
Calculate welding heat input in kJ/mm and kJ/in from voltage, amperage and travel speed, using the arc efficiency factor for your process.
Welding Rod Consumption Calculator
Estimate how many stick welding rods a job needs from weld metal weight, SMAW deposition efficiency and rod weight, with electrode pounds.
