Dear experts,
Please help out to clear my doubt.
I have qualified a WPS/PQR with impact -29 deg C, now customer want the WPS/PQR shall be qualified with impact in -46 deg C. Also there is no remaining coupon piece available for impact testing with -46 deg C.
My question here is, should I weld a coupon and only do impact test as required by customer and attached to PQR will be sort out this issue.?
or
Should I REDO a PQR with all mechanical test which includes Tensile, Hardness, Bend along with impact will sort our this issue.?
