Harrold,
I would think that you would still have to run within the parameters of the WPS. I agree that the code doesn't mention a change in electrode size as an essential variable for welder quals.
You just can't take any thing for granted when it comes to the code, that's for sure. I thought I had the interpretation of the code down pat, (D1.3) and I am finding out I don't. But I am learning new things and realizing even the best have questions about interperation.
Please don't take my last statement as a anouncement that I am one of the elite, I'm far from there.
Ramble, ramble,ramble
