Thank you EnergyMix.
Another thing that I want to clarify is for two base metals with different thicknesses but with the same P No., if preheating is required, which thickness will govern the preheating requirement? Is it the thicker material?
Need your technical expertise on welding for ASME Section III Div 2 and here is the situation:
There are two plates with different thicknesses, 38 mm and 6 mm. They will be welded together by FCAW. The selected WPS preheat temperature (min): 10C(t>25.4mm:95C). Ambient temperature is normal.
