Weld repairs per B31.3
Weld repairs per B31.3
(OP)
Does B31.3 limit the number of times a defective weld can be repaired? We have stainless welds in the fuel gas system where some welds were repaired twice.

Check your piping specification - as metengr stated there is no code requirement to reject a weld based on multiple repairs so if the client has just decided they don't like something the rework is at their cost.
I frequently see that requirement (1 x repair only allowed) in piping specifications for Duplex, Super Duplex and Titanium materials but cannot remember seeing it listed for stainless welds.
As for the spacing between welds, that again should be listed in the piping specification if it is considered critical.

In most such contract requirements, only the complete, defective weld need be cut out and you do not need to replace with a pup piece; why make two welds unless dinensional requirements cannot be met?
