I have one query regarding the heat input.
If I am welding a joint with multipass, then I have diffrent heat
input for every pass depening on the parameters. now I want to know
which heat input shall be taken into consideration for the effect of
heat input on base metal, cauz every pass has its effect on base metal
and after every pass due to the previous heat input I am giving extra
heat in the base metal.
So I want to know should I take individual heat input or sum of all
heat input for getting the exact effect of Heat input on base metal.
Regards
Sandeep Kumar
