Mr. Mubean,
Agree with what others have said But, before proceeding with another coupon plate welding, please check out,
1. whether the consumables you are using/have used, shall meet the impact
values at -46 deg C. If not the entire exercise will become futile.
2. Whether the base metal selected earlier could meet the said impact norms , if not it may
not be required to do -46 deg. C impact for consumables used.
3. ASME sec IX does not ask for hardness as such. If you have done hardness test for
your jobs, you could be following ISO 15614-1 or any equivalent code, then you may
require impact for base metal, HAZ apart from the weld zone.
4. Pl. check up before proceeding further.
sridhar.

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.?
