Welding of cladded pipes
Welding of cladded pipes
(OP)
Dear members,
I am a very novice for cladded piping.
My questions are;
1. Are there any special requirements when welding between inconel 625 cladded carbon steel pipes to be used in sour service?
2. Should welding between inconel 625 cladded carbon steel pipes be done at manufacturers' shop? I wonder if this welding could be done at site under sound WPS&PQR and what the general practice is.
Thanks in advance.......

Contact a clad steel manufacturer for details.
In general, strip the clad side back, weld the carbon side, then finish the clad side with clad alloy. Or do the whole thing with clad alloy.
