I worked with magnesium in the lab when I was in college. The problem with
trying to weld it is when it gets
heated ti high temps it ignites. It is what is used in military night time
illumination flares. It burns extremely hat and can't be put out using
conventional fire suppression means , It will burn in an atmosphere of
Nitrogen,Carbon Dioxide, and under water. It must be covered with sand to
deprive it of any atmosphere. It can burn at temps as high as 5610 degrees
F. So this is not something that you want to fool around with.
Check this sight or just google welding and repairing Campagnolo
magnesium wheel.
Good Luck , Your going to need it!
