It is purely manfacturing mistake and tracebility of Picked Items
....Construction has to check before weld the 2 elbows..If it is not
possible then raise the waiver ...
However In my work experience also I was faced lke this erorrs ,but we
have done 100 % RT and UT for two long seams meeting area ....
Thats All we can do ..In your case PWHT will be added .
Thanks
Suresh
