Distance Between Welds to Avoid Overlapping HAZ's?
(OP)
Hi guys. I know there is a rule of thumb out there someplace for spacing between adjacent buttwelds so as to avoid overlapping the HAZ's. I seem to remember it being one inch or one diameter. This is for P1 materials. What do you all say? Thanks guys! Pete

It normally comes down to the judgement of the metalurgist / welding engineer depending on the material, size, wall thickness and design code or instalation specification.

Also: There's usually a good reason why everyone does it that way
