Dear Friends,I have to do a welding procedure for welding SA203 Gr.E to SA 516 Gr.70. Process GTAW+SMAW. The joint thickness is 19.0 mm. The MDMT for 516 gr.70 portion of vessel is minus 29 degree C and the MDMT of SA 203 side is minus 87 degree C. The CS portion is exempted from impact test as per curve D in Sec. Viii Div.1. SA 203 Gr.E is also reffed in Curve D.Is it required to do impact testing of this joint?. If it required, at what temperature? .-29 degree C or -87 degree C?.If it is required, which HAZ I have to test?. 203 side or 516 side?.PWHT is asked for 203 material side.
