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"

Preheat calculator for welding & Carbon Equivalent calculator & heat input.
Preheat calculator for welding - EN1011 - Non Alloyed And Low Alloy Steels.
Android App for calculating required preheat temperature for welding. You will get inbuilt Heat energy, Heat input and carbon equivalent calculator as well inside this app.

Steps to Calculate Preheat temperature for welding.

1-Input or calculate heat input using inbuilt heat input calculator.
2-Calculate Carbon equivalent using inbuilt calculator.
3-Select Hydrogen scale / Weld process.
4-Input combined thickness.
5-Click on Calculate Heat Input.
