impact testing of welding consumable , ASME VIII Div 1
gigi
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.

You have to qualify WPS with impact test at mdmt.

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

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 ?

Dear Gents,
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 ) was used ?
Ramesh
My understanding about UCS-67(a)(3) as below
Your PQR impact testing may be exempted provided
1 .Your Filler metal
shall be classified by their manufacturer through impact testing at a
temperature not warmer than the MDMT
But, In your case, TC has been reported as -30 Deg C. You can use these batch consumables up to -30 Deg C MDMT without impact testing ( Not for -45 Deg C MDMT) hence exemption is NOT applicable for you.
2. Additional testing beyond the scope of the SFA specification may be performed by the filler metal and/or flux manufacturer to expand their classification for a broader range of temperatures - which is self-explanatory - you need to have TC for -45 Deg C tested temperature
Also I have attached some relevant interpretation details for your reference
Official web page for all interpretation available in link below. You may find many interpretation available related to this topic.

Prabhu kumar Loganathan
Your interpretation is correct as specified in below mail.
Impact test exempted for PQR qualification i.e. weld and HAZ, provided welding filler metal as specified in SFA specification shall confirm CVN test at MDMT or Colder temperature.
In this case filler metal is specified with -30 Deg. C CVN test and MDMT is -46 Deg. C and hence welding filler metal shall be tested at -46 Deg. C. This requirement shall be included in the PO stage itself so that filler metal manufacturer shall take care of impact test at -46 Deg. C (with minor medication of elements to improve toughness). Do not procure and test at -46 Deg. C with may pass for some batch and however it shall be ensured by the filler metal manufacturer.
Hope it is clear.

To add to below mail, alternatively you can select ER80SNi-1 which is classified for -46 Deg. C provided Ni content shall be <1% for sour service application.
