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.

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. Aftab Ahmad 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,
