Re: [MW:34240] ER80S-G/ER80S-Ni1

Dear,

There is no Chemical composition specified in SFA  5.28   ER 80SG in accordance with ASME Sec.IIC and as long as it meets the other requirements of the Code, Manufacturer has the option to vary the chemical composition. Normally in ASME equipment, we get each Batch/lot of the Manufacturer's welding consumable certificate certified by an ASME AI that it belongs to a unique A-Number.

Similarly in Pipeline jobs, ER 80S-G is not specified in Filler metal grouping according to API 1104 2021 edition as per the snapshot below.

Since your PQR is qualified with ER80S-G, you can do production jobs with each batch of filler certified by Client.

But client requirement for Repair is to use ER 80SNi-1 which has a restricted chemical composition mostly restricting Ni less than 1% for sour service.

Hence you have to produce the Welding Manufacturer Consumable certificate for ER 80S-G  & ER80SNi-1(code reference) to the Client and assure that the chemical compositions of both Filler are matching or are within the Limits of ER80SNi-1 code requirement. 

Thanks & Regards

Dear experts,

I would appreciate your valuable response regarding the following inquiry.

The filler wire mentioned below is approved for our normal Gas Metal Arc Welding (GMAW) Welding Procedure Specification (WPS):

·        AWS Classification: ER80S-G

·        SFA Specification: 5.28

·        API 1104 Group: 5

·        Trade Name: PIPELINER 80Ni1

·        Base metal API 5L Gr. X65

However, for repair welding joints, our approved WPS (GMAW Welding) specifies the use of the following filler wire:

·        AWS Classification: ER80S-Ni1

·        SFA Specification: 5.28

·        API 1104 Group: 5

·        Trade Name: PIPELINER 80Ni1

·        Base metal API 5L Gr. X65

Unfortunately, my team used AWS Classification ER80S-G for the repair welding using Repair WPS.

I would like to know if this deviation is acceptable or if any corrective actions are necessary.

Thank you for your expertise and guidance.


Regards,

Baqer
