Dear , Punching is only for the traceability & identification , few codes accept hard punching in terms of criticality & application criteria. impression marks must not in depth means should not affect thickness and should not create any undue stress
ASME VIII Div 1 , Subsection A - Part UG - clause UG - 10 -General requirements - enlighten more
