Anyone seen those easy aluminium welding rods advertised on the internet ?? What I'm wondering is could they be used to repair a crack in an alloy wheel ?? (My thinking being if it cools hard enough to be tapped could it be hard enough for an alloy ??) Cheers

Thanks Chris, I'll look into that if it doesn't work, Nigel

Thanks Strikey, I think that actually the stuff I bought months ago (but have never tried yet,) Nigel

don't think i'd be brave (or daft) enough to try and repair a wheel with this but to salvage a non structural casting or thread i would probably give it a go.

Find a mate with a TIG - I repaired my mates Golf GTD alloy within a couple of hours one morning having never tried it before - The surprise that I found was how long the crack was and how much heat I had to put into it - and the TIG is pretty focused in where it puts the heat. As you are effectively soldering that could be a lot of wheel to get warm.

i would think it would probably be ok to build up a kerbed but sound rim lip...possibly...maybe?

Thanks all, I think I'll have the repair tig'd.

Repairs done with these tend to crack at the first sniff of stress. A definite no on wheels imo.

Nigel - A slight trek for you but I have a specialist wheel repairer that I use that will weld it for you but will also check it for true - straighten if required - even refinish it required - not the cheapest option but they are very good at what they do - more to the point wheels is all that they do - they are in Basingstoke - link below www.myalloys.co.uk/

I used lumiweld years ago to repair an aluminium manifold. It was an absolute so and so to get heated up enough with mapp gas in a plumbers torch. The repair area had to be scrupulously clean, no ferrous contamination. I think the pack even came with a stainless steel wire brush to stop you using a normal one. Once done, the repair was much much harder to file than the surrounding metal. It was on par with trying to file a steel insert embedded in aluminium in that the insert stood proud.
I suspect that the mass of an alloy wheel would sink the heat away too quickly unless you used something so powerful it would start to melt the wheel.
I wouldn't use it on something as critical as a wheel

Lets face it, an actual weld on a wheel is sketchy at best. Working for a wheel refurb company I've seen all sorts of wibblepoo ... one audi came in with a cracked rim, I took the wheel off and counted 8 separate welds around the circumference already been done. I'd sooner get another matching alloy

Thanks Madmog & okp, Thinking that's probably the way I will go.

I have been welding for some time but I wouldn't weld that. I do have a contact that can do a proper weld and true the wheel properly. I do mean properly if you can't find a used wheel

I suspect that the mass of an alloy wheel would sink the heat away too quickly unless you used something so powerful it would start to melt the wheel. Exactly this. I bought some alloy welding stuff from a guy either at the NEC show, or at Race Retro, with repairing a cracked alloy in mind. Before I tried it, I mentioned it to someone I know who told me just what it says above - although the product is suitable for use with a normal blowtorch, the wheel itself just won't come up to temperature. I was always a bit dubious about trying it, but with local firms wanting £45+VAT "no warranty mate" to do the job, I figured it was worth a go. Never tried it, it's just another thing on the shelf that probably won't get used.

Aluminum alloys provide more of a challenge to welders than steel alloys. Aluminum has a lower melting point and higher conductivity than steels, which can result in burnthroughs, particularly in thinner aluminum sheets. Aluminum feeder wire is softer than its steel counterpart and can tangle in the feeder.
