The location of the crack: The only type of crack that is even marginally safe to weld is one on the back or inboard side of the wheel. A crack on the front face of the wheel compromises the structural integrity of the wheel, as does a crack on one of the spokes. A crack inside the barrel is also inadvisable to weld.
Why do aluminum wheels crack?
Impacts from pot holes, road debris, and other road hazards are the main reason why alloy wheels crack and bend. Aluminum is a brittle metal, which is why they crack. About 80% of the cracked wheels we see are also bent. The impact that caused the crack also caused the bend.
Is it OK to weld alloy wheels?
We've heard many people suggest that welding alloy wheels isn't safe, but it's very a reliable and effective repair method when done correctly. Simply welding over the crack wouldn't be safe, as the corrosion that led to the crack would remain, and this would still be the wheel's weakest point.
Why do my rims keep cracking?
The first and honestly one of the most likely causes of rim damage is working with tires that are too low for the roughness of the road. Every time you go over a bump, the springiness of well-inflated tires absorbs that bump and keeps the hard metal of the inner wheel and rim safe.

Why do you need to preheat a welding machine?
This is because welding locally heats and expands the metal, which causes very high stresses around the repair area. You can reduce these stresses by preheating the metal to be welded. If you do, remember not to preheat any of the heat-treatable alloys above 250 degrees F.
Can you use a torch with a GTAW?
In general, you have more control over the puddle with G TAW. Additionally, because the heat source and the wire feed are independent with GTAW, you can use your torch to provide extra heat where needed without adding wire. I recommend using GTAW for repair whenever possible. About the Author.
Can you repair a crack in aluminum?
Is aluminum different? Yes, in one very important way. Remember that aluminum forms an oxide layer almost immediately upon exposure to air. The crack’s surface also has an oxide layer. If you try to repair the crack merely by welding over it, the oxide layer will keep the crack from mending, and it will still be there after welding. Therefore, to repair a crack in aluminum, you must first excavate the cracked area with a grinding wheel or burr and completely remove the crack. Only then can you repair weld it.
What is the crack on the back of a wheel?
The direction of the crack: Most of the time, a crack on the back side of the wheel will cross the flange and bead area at right angles to the direction the wheel spins. This type of crack can be welded, because it can be opened up to accept the weld.
Where is the crack on a wheel?
The location of the crack: The only type of crack that we believe is even marginally safe to weld is one on the back, or inboard side of the wheel. A crack on the front face of the wheel compromises the structural integrity of the wheel, as does a crack on one of the spokes.
What is the process of welding aluminum alloy?
The skill of the welder: Aluminium alloy must be welded with a process called TIG (Tungsten Inert Gas) welding. I’ve seen many aluminium wheels that were MIG (Metal Inert Gas) welded, and it’s a disaster. The bead is much thinner and weaker, and the process burns the heck out the surrounding alloy, weakening the entyre area around the weld. Wheels should only be welded by an experienced welder who knows TIG welding, as well as knowing how to deal with wheels specifically.
How to smooth a wheel after welding?
Some shops will grind the bead down and smooth it out on both sides, or even smooth the whole area with a computer numeric control lathe, usually in preparation for repainting or remachining the wheel. Some shops will smooth the outside of the barrel but leave the bead on the inside to make sure the weld stays as strong as possible.
Can an alloy wheel crack?
Usually a good deep pothole or raised manhole cover is what does it. Cracks are extremely dangerous, and not just for the obvious reason that they can let the air out of your tyre . There’s also the fact that they can let the air out of your tyre very quickly and without warning.
Can you lose an entyre chunk of wheel?
The issue is that a crack like that is going to grow, and it will usually not even take as hard an impact to widen it as the impact that originally caused the crack. If the crack turns to one side, or splits into a “Y” shape, there is the possibility that you could catastrophically lose an entyre chunk of wheel.
Should a wheel be straightened before welding?
Ideally, the wheel should be straightened before welding. An impact that will crack a wheel will almost certainly have bent it as well, and trying to substantially straighten a wheel after welding stands a good chance of breaking the weld.
