Greetings Experts,
I would like to know more about PQR qualifications for Boiler tube material EN 10216-2 16Mo3 or SA 209 T1 with 6.5mm Thick,
Welding Consumable: Should I qualify the above material with ER80S-B2/ E8018-B2 or ER80S-D2 / E7018-A1, or which consumable is suitable for high temperature service like Boiler.
PWHT: As per ASME SEC.I & VIII PWHT is not mandatory for P. No.1 Gr.1 up to 16mm Thick and the Boiler tube and weld joints will undergo the Stress Relieving after tube bending as a coil. in this case Should i qualify the PQR with PWHT or Without PWHT.
