Hi
According to API 1104 5.4.2.3, "A major change in joint design(e.g from V groove to U groove) constitute an essential variable".
Question: if we have a PQR with single V butt weld (weld type:groove,Joint type:butt)is it possible to support welding of a joint below?
weld type:groove,
joint type:T,
single half V
all other essential variables do not change and technical subject will be met.
