Dear sandeep,
However as mentioned by Dinesh, voltage, current & travel speed as the important factors afftecting the heat input.
as per my past experience related to SMAW we used to control these factors by increasing the travel speed thereby resulting in good impact values. I am not sure about GMAW, whether this method can be applicable.
Another factor which effects the energy value is the choice of consumables.

Dear All
How we can get better impact values in HAZ with GMAW process in non
alloyed carbon steel?
like with multi pass welding.
Please provide your valuable ideas.
Regards
Sandeep Kumar
