⚡ Welding Heat Input (kJ/in = [60 x V x A] / [1,000 x Travel Speed in/min] x η)

Welding Heat Input & Cooling Rate Calculator

Calculate real-time welding heat input and heat-affected zone (HAZ) cooling rate (t8/5 transition time from 800°C to 500°C) under ASME Section IX & EN 1011-2: calculate arc energy (kJ/inch based on arc voltage, amperage, travel speed, and thermal efficiency η for SMAW/GMAW/GTAW/SAW), prevent grain coarsening, and welding engineer profits.
