Monnel ( SB 163 N04400) to SA 516 Gr 70 welding

[Merzi]

I plan to run welding procedure with SB163 N04400 to Sa 516 Gr 70 , and I need some advise . This procedure will be used for welding tube to tube sheet joint.

Use the GTAW process with a Ni-base filler metal (Incoweld A or other equivalent). I would qualify the WPS on a mock-up simulating seal welding and evaluate the weld joint by pull tests.
