| Abstract: | Welded blanks of magnesium alloy had been manufactured by gas tungsten arc welded(GTAW),which the magnesium alloy sheets were AZ31and AZ80 and thickness being 0.8mm.It had been analyzed that the welding properties of magnesium alloy sheet and lacunas.Technology parameters of GTAW were determined by experiment study.The research results presented that the grains were isometric crystal in welded seam,and the grains were branching crystal in heat-affected zone(HAZ).The lacunas were air hole and thermal crack i... |
