武汉纺织大学，武汉，中国。M. Wang，G. z. Wang，华中科技大学，武汉，中国加入铝合金时，最大的挑战之一是形成孔隙，这会降低焊缝的机械性能。对厚度为2 mm的5754铝合金薄板进行了搭接焊接，研究了不同激光焊接工艺参数对焊缝质量的影响。通过X射线检查测量孔隙率含量。关键是控制熔池的凝固时间。当熔池凝固时间足够长时，更多的气泡可以从熔池中逸出，而较少的气泡以气孔形式残留。
J. Wang, Wuhan Textile University, Wuhan, China C. M. Wang, G. Z. Wang, Huazhong University of Science and Technology, Wuhan, China When joining the aluminum alloys, one of the biggest challenges is the formation of porosity, which deteriorates mechanical properties of welds. In this study, the lap welding was conducted on an aluminum alloy 5754 metal sheets with a thickness of 2 mm. The effects of various laser welding parameters on the weld quality were investigated. The porosity content was measured by X-ray inspections. The key is to control the solidification duration of molten pool. When the solidification duration of molten pool is large enough, more bubbles can escape from the molten pool and less remain as porosity.
