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.
Best regards,
Shashank Vagal

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.

Subject: [MW:7635] Change in electrode manufacturer 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,
