Re: [MW:15205] Impact Test clarification

I disagree, nowhere ASME VIII -1 is setting any requirement for the filler material as row material. If your impact test is in fully with ASMEVIII-1 requirements you are OK

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.

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.? 

Requesting you to please provide me ASME IX clause reference.

Anticipating for you kind help. 

Thanks & Regards. 
M.K.Mubeen
