Welding A333 Gr.6 ASME 31.3
Welding A333 Gr.6 ASME 31.3
(OP)
hi there, i am qualifying the welding procedure for A333-Gr.6 for welding of fabrication in accordance with ASME B31.3. I have some concerns needing your advice for the following cases:
#1: the design temperature - 39 degree C, so does PQR need to do impact test?
#2: the design temperature - 20 degree C, so does PQR need to do Impact test?
#3: the design temperature - 43 degree C, the base metal and consumable already was impact tested mentioned in the its certificate, does PQR need the additional impact test?
#1: the design temperature - 39 degree C, so does PQR need to do impact test?
#2: the design temperature - 20 degree C, so does PQR need to do Impact test?
#3: the design temperature - 43 degree C, the base metal and consumable already was impact tested mentioned in the its certificate, does PQR need the additional impact test?

Therefore for the cases above Column A of table 323.2.2 is applicable (Design Minimum Temperature at or Above Min. Temp. in Table A-1).
A-333 is not assigned on table A-1 to any curve of FIG. 323.2.2A. Therefore acc. to table 323.2.2 A-3(b) for:
#1: the design temperature - 39: HAZ and weld have to impact tested (MDMT < -29°C)
#2: the design temperature - 20: HAZ and weld must not be impact tested (MDMT ≥ -29°C)
#3: the design temperature - 43: HAZ and weld have to impact tested (MDMT < -29°C)
