采用CO2激光器对挤压成型的镁合金板材AZ31B进行平板拼焊,对不同焊接参数条件下焊缝的气孔率进行分析,从而弄清了激光焊接参数对其气孔率的影响,为进一步研究降低镁合金激光焊的气孔率奠定了基础。
CO2 laser was used to flatten the extruded magnesium alloy sheet AZ31B. The porosity of the weld under different welding parameters was analyzed to find out the effect of laser welding parameters on the porosity. In order to further study the effect of magnesium reduction Alloy laser welding porosity laid the foundation.
