Why? Welding magnesium alloy is done in exactly the same ways as
welding aluminium, except of course that different composition filler
rods are preferred. The relevant properties (strength of the base
metal, electrical conductivity, melting point of the metal, high
melting point of the oxide, hydrogen inclusion in the molten metal,
etc) are very similar.
