After welding your first pass welding stainless sockets elbows and flanges I know that there's a temperature range before you can weld your second pass so my question is at what temperature is it safe to weld my second pass?

Bit of reading but good info.

Thank you I read the entire file and there's no mention of interpass temperature and ranges. Although I did find some literature that stated to let it cool till it reaches 150 degrees before you can start your second pass. It's been 8 years since the last time I had to worry about that but on this job you better have your digital temperature Gun.
