Dear Sandeeph..
A. As per mr.Dinesh you have to reduce/minimize the heat input as much as low.
B. You can try for any post weld heat treatment..
Both will refine your grain size in HAZ so you will get more impact valve.

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.
