Gents,
I have confused on the above topic, could some one clarify the below situation
1) 21" ID ,Pipe (AISI 4130 ) cladded by INconel 625 with thickness of 1.5 mm with qualified Welding Procedure in other company.
2) We need to overlay the above item 1 , by inconel 625 on the existing Inconel 625
3) If i want to qualify the welder, i need to consider the Inconel 625 as base metal or AISI 4130 as base metal ?
Pls share your exp, in as this kind of situation
Thanks & regards,
K.Babu
