Point no 1
as per EN ISO 15607 clause 7, a WPS is A qualification is valid
indefinitely for the ranges qualified unless otherwise specified.
Point no. 2
For that you should need to know what is the yield strength of the
filler wire, if it is relative to S355 JR, then you can weld S355 JR
to S355 JR, or if it is relative to
S275 JR, then its not qualified.
Yes you can weld S275 JR to S275 JR with this WPS.
Because both material are from the same material group and your filler
wire properties are relative to it..
