Cracked Hug

Aluminum Alloy

Wheel

Hi. I need to repair the cracked hole. There is also half a stud (steel) still stuck in there, and I'm now looking at removing the helicoil and grinding out the stud, but can you give me any suggestions on what grade of wire I will need to re-weld and rebuild the area, before drilling a new hole?

It's an aluminum alloy hug from a motorcycle (pit bike) I have no idea what grade of metal it is? And struggling to find out? Any suggestions?

It's probably from China and no more than 5 years old. And it holds the rear chain sprocket on.

aluminum welding
by: weldalldamnday

I weld aluminum all day every day, and in my humble opinion, you won't go wrong with ER4043. I also would suggest using TIG and 100% argon. As for your stuck stud, an easy out should get it for you. Clean the area to be welded thoroughly prior to welding. Fill the hole solid and re - tap your hole. Hopefully this helps you out.

Some Aluminum Not Weldable?
by: Anonymous

Some aluminum isn't considered to be weldable. But that being said Aircraft Spruce offers welding rods that weld "unweldable" aluminum. I am not sure but I think rod advertised in rod usually seen at demonstrations where 2 aluminum cans are welded together.
