Welding magnesium is NOT for the faint of heart,....

I've made small welds to mag cases in certain areas but I've not attempted to attach stiffening ribs.

Many years ago, I heard of someone who tried that with no long-term success. Due to the different alloys used in the mag case and the available materials, the case cracked all around the attached ribs.

Thats why the Factory (who patented magnesium pressure-casting in 1968) gave up and went back to aluminum.

Mag cases are fine if they have been properly prepared, but they simply have their limitations.
