How many Charpy V specimens?
How many Charpy V specimens?
(OP)
I searched the forums but could not find an answer.
I'm qualifying a WPS with GMAW and FCAW on 1-1/2" P1 gr2 plate. GMAW root and FCAW filler and cover passes. Charpy testing will be at -50 F.
This will be done per B31.3.
From what I've read, it looks like I will need 3 specimens per set of impact tests. So how many total charpy tests do I need?
Is it 3 for HAZ, 3 for weld metal, 3 for base plate?
This will be my first charpy V procedure.
Any help or comments are always appreciated

Regarding locations, see B31.3, Table 323.2.2, and corresponding text below

lower than the minimum shown in Table A-1 or
Fig. 323.2.2A (including Notes), unless prohibited in
Table 323.2.2, Table A-1, or elsewhere in the Code, and
provided that the base metal, weld deposits, and HAZ
are qualified as required by the applicable entry in

what kind of wire are you using?

So do I need 3 total tests, or 3 tests for HAZ, 3 for weld metal, 3 for base plate?

Contact your lab, give them the thickness of the test plate and tell them your intentions. They'll be able to provide some guidance on test plate length required to yield all of the specimens.
