Welding Tips and Tricks

Hey, I was wondering if anyone has any advice about letting metal cool before tackling it again. I've done small diameter pipe, thick plate as well as many other projects and have learned to let them cool before getting back at it. But I don't really know when or what temperature the metal should be to get back at it, or what temperature is too much. Any advice?
Thanks ahead of time!

It's a good idea if you have the pleasure of having other work to do (if this is your day job), some codes require a certain interpass temps, so you have to watch that.

Over heating any material is generally a bad idea, but I would rather comment about a specific part instead of trying to cover such a broad scope of what someone may be welding that I have no knowledge of

My current job is welding carbon steel pipe of many sizes (usually 12'' and smaller) with multiple passes. Switching between work is good advice. Is there a general rule about interpass temps? I would love to have a number in my head. Every project I've done in the past I've just guestimated and would love some advice on the subject.

The WPS should call it out. If it’s not specified then I would suggest getting some temp sticks for 150F. That’s a common temp for carbon pipe.
