Welding interpass Temperature
Welding interpass Temperature
(OP)
Hello.. I'm doing a WPS and when try to define point QW-406, I got freezed, because I was trying to find some information about how determining interpass temperature when welding low carbon steel pipes (ASTM A106B). I read something in asme Section IX and AWS D1.1 but it is not so clear... there talk about "cooling rate" but never specify this value, refer to a chart or formula....
Can some body help me?
Best Regards
Alejandro.

RE: Welding interpass Temperature
For carbon steels, the maximum interpass temperature is around 600 deg F. As you go to higher alloy steels or air hardening steels, the maximum interpass temperature may be less than 600 deg F to avoid adding too much heat into the surrounding base material recognizing that you want to increase arc time for weld production.
RE: Welding interpass Temperature
Control during production welding is highly recommended to obtain superior mechanical and corrosion resistance properties.
