(OP)
Does WPS qualified to asme ix get obsolete overtime. I know based on qw 100.3 that wps made using 1962 ed and above can be used for PV fabrication.
I just being question that our wps is quite old and he request to requalified our wps. His argument is that old material get obsolete and not suitable for current use. I dont think chemical composition change is essential variable for wps.
Anybody know how can i answer this.
