[MW:2345] Heat Input formula

 

Friends,

 

I have got the following formulae for calculating the heat input for SMAW and other welding processes’. Pl confirm which one is correct. As far as I am concerned, I am following the FIRST SET for all the process.

 

First Set:

 

1. Max Amp x Max V / Min Speed : Max Heat Input
2. Min Amp x Min V / Max Speed : Min Heat Input

 

Second Set:

 

1. Max Amp x Max V / Max Speed : Max Heat Input
2. Min Amp x Min V / Min Speed : Min Heat Input

 

Third set:

 

1. Min Amp x Max Volts /Min Speed : Maximum Heat Input
2. Max Amp x Min Volt / Max Speed : Minimum Heat Input

 

 

Regards,

Vasanth
