The gap is required to release the fume gases which generated during welding. No gap required after welding(I don't see any reason). You can check with 4 mm gap during fit up to meet client requirement.

Subject: [MW:15368] Re: Socket weld gap requirement
no it it not required after welding, many times gap closes to zero due
to shrinkage during welding. if your client requires the gap after
welding (I don't see any reason for this) probably you need fit up
with more gap.
