I had a wheel repaired a while ago and was gonna have a go myself but due to it being an important part and extremely rare wheel I passed on doing it myself.

Someone had repaired it with ally rod and as the guy explained to me it just ends up very brittle and porous, you can literally just snap it off with a pair of pliers, my wheel looked pretty good until we mounted the tyre and inflated it, straightaway the welded ally part flew across the workshop !!!

The guy that did it knew I could weld and offered an old rim and some rods to have a go, To be honest it was just like welding ally, he just kept saying don't get it too hot near its combustion point, apparently thats when it can ignite, had no problems at all and would do it myself next time without hesitation.

Here are some broken pics










Here are the repaired pics

Nice job, bet that took a few rods.

Looks like it belongs on the front of a willys Steve.....so all in all magnesium is relatively easy to repair then.

We had a few magnesium engine cases on MX bikes welded up several years ago - my brother used to send them to a bloke in Somerset if I remember correctly posted Monday back by Friday and he did a good job too. Those bikes have since long gone - I give it up and my brother now rides much newer bikes so no problems with bits failing or stress cracks forming. I'll ask him tomorrow if he still has the contact details...

I expect this might well be all in hand by now but I finally got an answer from my brother. These are the people that welded our magnesium alloy castings - Redline Engineering Dorset https://plus.google.com/105300282688917597823/about?gl=uk&hl=en

Can't find a website but descriptions for the business mention being tig welding and motorbike rebuilding specialists.

Job Done.
Went very well seems to weld much like alu apart from you can almost
bury the tungsten.
I am happy I know its not great but the weld seems good enough to be a usable part again.

Thanks for the rods Pete and the advice.
