Change in electrode manufacturer

[krishna]

Hi frnds,
Please clarify the below

we have qualified a welding procedure with ESAB E07018 and it is passed we are doing the production welding .

Now we have no stock of ESAB so we are using HONAVAR Electrodes with the same WPS.

Is it acceptable or we have to make another procedure with honavar electordes.

regards,
kk

Hi, You can use.The brand is a non essential variable.   Thanks & Regards,   (Karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.

Your question is interesting. As long as the code is concerned, electrodes brands are not essential parameter and it should not require re-qualification of WPS. But some times it happens that with one brand of electrodes some times WPS does not qualify and just by switching from one brand to another brand the same WPS qualifies. It shows that brands play a very important role in qualification of WPS that can be ignored despite the electrodes brands conform to the standard. I would ask forum for their expert opinion in significance of the electrode brands in qualification of the WPS.  

 

Best Wishes

Dear Mr.Karthik,
That means no need to prepare seperate WPS,SHALL WE CONTINUE WITH SAME WPS and use honavar electodes.
thanks,

Dear All

Can you clarify whether this is applicable in situations like Sour Service.

My understanding is that: For Sour Service requirement, because no consumables are established till date, shall qualify the brand, batch and AWS classification. The same brand and batch shall be used in production welding also.

Please correct me if I'm wrong.

Regards

Hi, Yes.You can use the existing wps.

Hi, Yes.But you have to confirm with your customer specification also.Some customer have mentioned about the brand name of electrode to be used for the particular job/project.   Thanks & Regards,   (karthik)

Dear All

Some companies specification don't allow to change electrode brand or batch, so you have to follow your company specification, in some cases for SMAW if impact tests are required the brand of the electrode can not be changed without further impact tests

Kind Regards

Mahmoud

Hi

If your code is ASME Sec. IX, You can use as it is identifiable with the A no.

If A no. is not applicable then you have to prove for same chemical composition or restrict with the same brand as PQR.

Thanks and Best regards,
K.Rajagopal

Dear Krishna,

If your WPS is showing the brand name then you have to revise it say any brand.

Then you can use.

Thanks and best regards,

Hi all, Perhaps those who have sufficient experience should share here their knowledge as to which brands are compatible. I mean, if a WPS is qualified with one brand, say X, of electrodes, then which other brands, say Y, Z etc can easily replace this X if required - with some acceptable proof to back it up, of course. I thinks this would help all when due to many reasons a particular brand used in the PQR is not available for some reasons and you can not afford to stop the work.

Hi KK,

 

Sec-IX, QW-404.12 addresses your concern. Change of electrode brand within the same SFA number is not an essential variable as per Sec-IX. However if there are requirements such as:-

• impact at low temperature (e.g -45 degC) or requirements such sour service requirements (MR-0175), then it's advisable to check the electrode MTR's thoroughly so as to ensure that all design requirements are being met.

 

Thanks.

QW-404.12 A change in the filler metal classification within an SFA specification, or for a filler metal not covered by an SFA specification or a filler metal with a “G” suffixwithin an SFA specification, a change in the trade designation of the filler metal.
