Welding Heat Input Calc

Compute arc power, arc energy, and net heat input in seconds with metric or imperial workflow for real shop-floor procedure checks.

Weld Heat Input Pro is a focused engineering utility for welding procedure qualification and production control. Enter arc voltage, current, travel speed, and thermal efficiency to calculate arc power (kW), arc energy (kJ/mm), and net heat input in both kJ/mm and kJ/in. The app is built for practical WPS/PQR verification with decimal-pad data entry, fast keyboard dismissal, and metric/imperial switching.
