Heat Input

By BOON 2 Date 05-12-2007 09:28

In one of our project, a client had commented that heat input was not addressed in WPS (ASME code) sumitted.
I would like to know more on heat input during welding.
1) Can someone advise what is the formula use to caculate the heat input.
2) On the WPS, which section should the heat input be placed. QW-409?
3) How does the value of heat input affect welded joints.
4) Is there a recommended range for heat input when welding with GTAW process on stainless steel?

Regards,
Boon
