Heat input calculator for arc welding is made for directly calculate heat input or heat energy added while welding as seam or joint.

You can calculate heat input of below welding processes using this android app.

1-MIG/MAG/GMAW - gas metal arc welding
2-TIG/WIG/GTAW - Gas tungsten arc welding or tungsten inert gas welding.
3-PAW - Plasma arc welding.
4-SMAW/MMAW - Shielded metal arc welding or Manual metal arc welding
5-SAW - Submerged metal arc welding
6-FCAW/MCAW - Flux cored arc welding or Metal cored arc welding.

How to calculate heat input of welding for above processes?

1-Open App
2-Input current in Amps, Voltage in Volts and Travel speed in mm/min, inch/min, cm/min or m/min the unit of HI depend on unit of Travel speed for eg. If you input HI in mm/min then calculated HI will be KJ/mm.
and thermal efficiency for welding process as listed in app.
3-Then click on "Calculate heat input"
