An evaluation of the macro- and microstructure of magnesium alloy tungsten arc-welded butt joints is presented in this paper. Al-Zn-Mn magnesium alloys are taken into consideration in the research. Their main alloying elements are zinc and aluminum, respectively. The dendritic microstructure of the base metal is obtained. The analysis shows that achieving good-quality butt joints of magnesium alloys is possible.Downloads
