Welding Heat Input Calculator

Estimate stainless steel welding heat input from voltage, current, travel speed and efficiency.

Welding Heat Input Calculator

Enter voltage, current, travel speed and process efficiency.

FormulaHeat input (kJ/mm) = voltage × current × 60 × efficiency ÷ (1,000 × travel speed).

Enter values and keep the result with the quotation assumptions.

Calculation result

Enter values and calculate.

Use the estimate to compare welding procedures, then confirm the qualified procedure specification and heat affected zone limits.

Technical reference

Welding Heat Input Calculator basis and limits

This calculator provides a planning estimate for welding heat input calculator using the stated dimensions, material assumptions and operating inputs.

Confirm grade, applicable standard, tolerance, product condition and supplier documentation before making a final engineering or purchasing decision.

Important Use the result for quotation preparation and early planning; it does not replace a certified measurement, drawing review or supplier confirmation.

Calculation method

Formula and worked example

01

Welding Heat Input Calculator formula

Use the inputs and units shown in the calculator, then review the assumptions before using the estimate.

Heat input (kJ/mm) = voltage × current × 60 × efficiency ÷ (1,000 × travel speed).
02

Worked example

At 24 V, 180 A, 120 mm/min and 0.8 efficiency, estimated heat input is 1.728 kJ/mm.

24 × 180 × 60 × 0.8 ÷ (1,000 × 120) = 1.728 kJ/mm
