ASME 1 PW 53.9
ASME 1 PW 53.9
(OP)
I'm doing a vessel test plate that is 4.7" thick and has to be tested to PW 53.9. Everything is pretty standard with exception to the bend test.
53.9.1 says the width of the transverse bend specimen is to be 1.5 "T" which makes the specimen width 7".
Is this the true intent?

PW-53.8 covers tensile test requirements for two types of specimens: a "joint test" specimen and a "weld metal" test specimen.
PW-53.9 establishes requirements for "free bend" tests as opposed to "guided bend" tests typically used for welding procedures & performance qualification covered in ASME Section IX.

.....When the capacity of
the available testing machines does not permit testing a
specimen of the full thickness of the welded plate, the
specimen may be cut with a thin saw into as many portions
of the thickness as necessary, each of which shall be tested
and shall meet the requirements.

Does this only mean the thickness and not the width?
My first impression after reading this requirement of a performing a bend test was to utilize a guided bend test jig. A jig for the width of 7" does not work well..if at all...so, I would guess that the limitation of the testing machine only applies to the thickness of the specimen and not the width of the specimen...am I correct?
