RE: [MW:27712] impact testing of welding consumable , ASME VIII Div 1

Dear Gent,

 

Non- impact tested WPS was used for some weld joint. Question :

·         If welding consumable ER70S-G have been impact tested at –30°C . As per para. UCS-67(a)(3), additional testing ( Impact test ) at –45°C is a requirement when WPS ( No impact test ) used ?

Hi

You mean , already welded using non-impact tested WPS/PQR ?

 

Your PQR should have been qualified with impact testing, then only para.UCS-67(a) is applicable for u

Seems, your consumable supplier supplied ER 70S-G with guaranteed values up to minus 30 deg C only, which may not suitable for your MDMT, unless tested.

Ask supplier to replace your consumable to meet your service requirements. 

 

​

As per ASME BPVC.II.C-2017 SFA-5.18/SFA-5.18M,

Impact testing requirements should have been agreed before you place order, since no requirements as per code

 

​ 

 

  Either case you should have qualified WPS/PQR to meet your service requirements . ​

You have to qualify WPS with impact test at mdmt.

Dear Experts,

 

Please help me to clarify issue as below:

 

Solid rod ER70S-G have been used for weld joints of HP Flare KO Drum by using WPS V02 (GTAW/SMAW – Impact test is not applied). Certificate of welding consumable ER70S-G indicates that impact test temperature is –30°C. Minimum design metal temperature (MDMT) of HP Flare KO Drum is –45°C. Material of HP Flare KO Drum is SA-516 Gr60 normalized.

In accordance with para.UCS-67(a)(3) ASME BPVC.VIII.1-2017 , is it a requirement to perform impact test at –45°C for welding consumable ER70S-G?

 

Thanks

 

Gigi.
