Hi, Mr. Manpreet, thanks for your reply.
Refering to Non-mandatory appendix JJ and UHA-51 (e) & (f) of ASME Sec. VIII Div. 1 2010 Ed., I think Impact testing is mandatory for welding procedure qualification and for austenitic S.S. welding consumables with MDMTs colder than (-104º C). In our job, MDMT is (-105º C.)
Exemption from Impact tesing is only applicable complying UHA-51 (g). I have no idea about desing stress and coincident ratio.
It will be appreciable if any body can focus on this.
Thanks & regards,
C. R. GANDHI
