Abstract:

Mature and reliable welding technology is an important guarantee for wide applications of magnesium alloys. This paper surveys the research advances in welding technology of magnesium alloys and analyses its disadvantages. Every welding technology has its own positives and negatives. Its selection should be based on its own characteristics and the specific requirements of the welding components. Tungsten inert gas welding, friction stir welding and laser beam welding have tremendous application potency, as compared with other welding technologies of magnesium alloys.

Key words: magnesium alloys, tungsten inert gas welding, friction stir welding, laser beam welding
