309 Weld Metal Impacts Required?
309 Weld Metal Impacts Required?
(OP)
On a weld procedure test to B31.3, are weld metal impacts still required when welding say, ferritic SS using 309? Obviously HAZ testing is still required. The MDMT is fairly high, well above the point where impacts are mandatory for austenitic SS weld metal.
The answer (yes) in VIII-1 appears to given in UHA-51.

Because being more familiar with VIII-1 I looked there for some guidance, not because I would ever assume the same rules apply. And the paragraph numbering system in the B31.x codes is not exactly memorable.
