Just 309 is ok. 316 with carbon steel will give hot cracks because of low FN. You need a filler metal with much higher Cr and Ni content to avoid low FN

Good day to all,

Please refer the attachment  for joint configuration, I have to qualify the procedure for AISI 316L to A516 Gr B steel

Thickness of the job maximum 64 mm. I proposed to use 35 mm thickness plate for qualification.Code requirement ASME Sec IX

My plan as follows

1) Buttering the Bevel area of A516 Gr B material using E 309 consumables up to 3 to 5 mm

2) Machining of Bevel & PT (NDT) & Fit up

3) Welding of A516 Gr B to to AISI 316L using E316 consumables 

Kindly  advice me what preheat temperature  & Interpass temperature can maintained during welding, Any PWHT required or not,any other precautionary measures during welding & mechanical testing.

My client not specified anything. Please someone advice to me.

Thanks

Regards
