I have a variator from the CVT of a scooter and a part of it got chipped off. I tried AC TIG welding it but i can't seem to make a decent weld puddle.
I tried welding on a sample piece of aluminum sheet and my weld seems to be fine on that one.
I don't know what's wrong but I was thinking maybe the variator isn't aluminum since the piece just chipped off and didn't bend. But then a very small portion of the aluminum rod did fuse to the variator.
Can aluminum be brittle like iron?
I tried sticking a magnet onto it but it's not magnetic.
