  • Welding of Magnesium Alloys | IntechOpen

    2012-7-11 · However, few studies on welding magnesium alloys by fiber lasers are conducted. It is reported that the UTS of the joint decreases, but the yield strength increases after fiber laser welding of fine-grained magnesium alloy (Yu et al., 2009). An IPG YLR 6000W fiber laser and a KUKA KR60 robot are shown in Fig. 10.
