Hi,
I have a carbon steel pipe spool with a circumfrential butt weld. Very close to the butt weld there is another circular double pad welded to the pipe using a fillet weld. The butt weld and fillet weld overlap around the circumfrence of the pipe, the Butt weld was competed probably a few weeks before the fillet was added.
I know this not good and normal practice, for me at least, is to have 4 x Wall thickness or 50mm separation between these welds.
Can anyone explain why it is a problem to weld one weld on top of another like this? Can this be accepted it we do 100% radiography and confirm there are no unacceptable includions in the joint?
Any help is appreciated, cheers.
