How to Calculate Welding Heat input calculation for TIG, MIG, SMAW & SAW Welding

Heat Input

Heat Input (KJ/mm or KJ/inch) =
Welding Process Thermal Efficiency
Tungsten inert gas (TIG) / gas tungsten arc welding (GTAW) 0.6
Plasma arc welding (PAW) 0.6
Metal inert/active gas (MIG/MAG) / gas metal arc welding (GMAW) 0.8
Flux cored arc welding (FCAW) / Metal cored (MCAW) 0.8
Manual metal arc welding(MMA)/shielded metal arc (SMAW) 0.8
Submerged arc welding (SAW) 1
