The Welding Heat Input Calculator estimates heat input per unit length using arc voltage, welding current, travel speed, and process efficiency. Convert results into kJ/mm, kJ/cm, or J/mm to support welding process planning and parameter comparison. Use this calculator as a reference estimate; actual heat input depends on the welding process and procedure.
Results
- Estimated heat input—kJ/mm
- Estimated heat input—kJ/cm
- Estimated heat input—J/mm
- Travel speed (converted)—mm/s
Results are estimates of arc heat input only. They do not replace a qualified welding procedure.
