RE: [MW:15191] Impact Test clarification

Mr.Mubeen,
 
No doubt you have to do re-test @ -46 deg C (PQR) for all the requirments, becuase varying of Heat inputs and welding parameters.

 


Thank & Best Regards,

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
