ASME IX Welding - Preheat and Interpass Temp. Suggestios for P8
ASME IX Welding - Preheat and Interpass Temp. Suggestios for P8
(OP)
ASME IX does not appear to give guidelines for preheat and interpass temperatures. I am interested in guidelines for preheat and interpass for P8 material, specifically 316 stainless when using GTAW welding.
ASME B31.3 gives 50F as the minimum recommended for P8. I did not find anything in this code on the interpass suggestion.
ASME IX seems to set the rules so that if whatever you can qualify you cannot put anything more than 100 Deg. F different on your WPS (406.1 and 406.3).
I appreciate any input.
