Dear members,

I have one query regarding WPS.

1) One of my client made a comment on a WPS which i had submitted to
them for approvel that  Procedures are from 2001.  My question is Is
there any time limit for WPS?  In my knowledge answer is No, a
qulified procedure can be used any time without changing the essential
variable.

2) I have one  qualified wps with base metal S 355 JR to S 275 JR.
Can I use this WPS to weld  S 355 JR to S 355 JR and S 275 JR to S 275
JR?

Please clear my doubts, if possible with code reference.

Thanks & Regards.

Manoj
