Proximity of Welds to Avoid HAZ?
Proximity of Welds to Avoid HAZ?
(OP)
Hi guys. I hope you are all well and enjoying the New Year.
I have a question. I know there is a rule of thumb for this but I can't remember it. How far apart do two adjacent pipe welds need to be in order to provide adequate separation between the two HAZs of the two welds? I seem to remember 2" being the rule of thumb.
Application: I have a 36" 316L sch 40S pipe that has a full encirclement split repad to provide reinforcement at an anchor. The repad is fillet-welded to the pipe at its two ends and also longitudinally to join the two halves. There is a fitting buttweld very close to one of the end fillet welds, i.e. the repad fillet weld is close to the fitting buttweld. I believe the two welds need to be at least 2" apart but I would like to hear what you think. This is a 31.3 system, if that matters. Thank you!!!
