At alloytechrefurbedrims we do all aspects of wheel repair and we do alloy wheel crack welding we would prefer not to weld the wheels but we do understand that wheels can be stupidly expensive to replace and by far the cheaper option is to get the wheel welded, so at least we can offer customers the correct way to weld a cracked wheel so the weld is strong,, we constantly see welds on wheels that are done wrong and do not and will not last as the weld is very week. however we do have a strict 2 crack per wheel policy and we will not weld anymore than 2 cracks in any one wheel .
our procedure of welding is as follows.
1..tyre and weights ,valve stripped off wheel
2,,we drill a small hole at end of wheel crack this stops crack traveling.
3 we cut through the crack with a 1.5mm cutting blade
4,, the wheels coating is then cleaned off around the crack on back of the wheel and also on top were tyre seats.
5,, we tig weld a thick amount of alluminium weld on the top of wheel were the tyre seats.
6,,then on the inside at rear of wheel we V cut the and take the old alluminium out up to the new weld.
6,,we then tig weld the v cut up to the new weld on the rear,(this means you get 100% penetration of new weld right through the original crack and joined on to the older alloy if you do notmanage full penetration there will be a hollow void between welds and it will crack again very easily.
7,,wheel is allowed to cool then we grind down the alloy on top of wheel were tyre seats to bead
8,,the bare alloy we cover with primer.
9,, new valve fitted tyre re fitted and inflated to 55 psi repair is then sprayed with a soap solution to pressure test the repair .
10,,finally once tested and everything is ok the wheel is balanced.
we prefer tig welding wheel alloy it is better and in our opinion a lot stronger as you can get the correct temperature into the metal which uniforms the alloys together, but with mig weld it is quicker but has been found to lack strength as uses a quicker heat which we think does not fully penetrate the metals together properly.
we charge £50 per crack to weld wheels that is you bringing us the wheel with or without tyre fitted.
£60 per crack weld if we have your car and have to axle stand remove and refit the wheel/s
we are not the cheapest but we are far from the dearest however we will weld it the correct way and give you a strong weld and your wheel the best chance to survive our roads.
