Yes. It is possible to gas cut face and root bend specimens under ASME IX BPVC, but do not flame-cut nonferrous materials. I would not quench such specimens after cutting. AWS B4.0 states "The specimens edges may be thermally cut but, in this case, at least 1/8 in. (3.0 mm) of material shall be mechanically removed from the thermally cut surface".
