Vivek,
Why did you go for production welding without passing impact test, so no question will come for gouging category A,B,C .

Dear Vivek,--70% of required average is ok, ur values r ok to pass the PTC.2011/12/27 Vivek Pandey <vivek....@gmail.com>
Respected All,
I want your suggestion about Impact test of vessel production test, I
have tested a stress relieved PTC Impact test on weld & HAZ AT -47
DEG. PTC has failed again I have done reheat treatment & Retest with
same cycle of the job. PTC has failed in one indivzual value by 1
joule.Value is like this way 28, 19, 34.
Is there any acceptance criteria as per ASME SECTION VIII DIV 1. other
wise all weld of category A B C D to be gauged & reweld.
Kindly solve my query as soon as possible
Regards
VIVEK PANDEY
