I am curious if anyone is having problems using Vibrants aluminum mandrels.

It's almost as if the material is contaminated all the way through. It's next to impossible to start a weld. And equally as hard to keep one going without running into serious problems.

I have tried MANY different methods of prep:
Acetone
SS wire brush
Grinders with numberous different wheels
scoth brite pads of all kinds
brake cleaner
purging
and combonations of those.

I know some of those should never be used. But I had to try.

NOTHING seems to work. And it's ONLY on T6061 Aluminum madrels from vibrant...

I am curious if any other welders/fabricators have the same issue.

Before anyone suggests switching suppliers. We would if we could get it somewhere else as quickly and efficeintly as we can vibrants stuff.
