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.
