From what I'm able to find in the D1.1 2020 :
- These are not direct quote but are my interpretations of the figures in the code.
(6.9) Side bend specimens in plate which is greater that 3/8" and up to 1 1/2" thick, the specimen shall be 3/8" wide x 6" long, with a maximum corner radius of 1/8"
(6.8) For transverse face and root bend specimens in plate which is 3/8" thick or less, the specimen shall be 1 1/12" wide x 6" long, with a thickness not less than the base metal plate (meaning when the weld reinforcement and backing have been removed the weld metal surfaces shall be flush with the rest of the plate) with a maximum corner radius of 1/8"
So I think your 1G groove tests on 1/2" plate should be side bends which are 3/8 wide and 6" long with a max corner radius of 1/8" (since the plate thickness is 1/2 there should be no machining or cutting to make the specimens less thick than the existing thickness of the plate, since it should be a side bend)
- again, this is my interpretation of what I'm seeing in the D1.1 code in section 6 - tables 6.8 and 6.9 on performance qualification.
Sounds like your inspector is doing it wrong.
