| 摘 要： | 针对激光-MAG电弧复合热源焊接过程的几个主要影响因素展开了研究.通过焊接电弧分析仪发现激光-MAG电弧复合热源焊接时,光斑-焊丝之间的距离为1mm时,焊接电弧最稳定.通过对熔深、熔宽的分析发现,复合后熔深能够增加1.5倍以上,并且激光-短路过渡电弧MAG复合热源焊接还能够改善焊缝的润湿性,增加熔宽,减弱焊缝的咬边现象,与单独激光焊接时相似,当激光的焦点位于工件表面以下1mm时,熔深达到最大值.

| Abstract: | Some influential factors in laser-MAG hybrid welding process were analyzed.By the analyzing device of welding arc,it was found that when the distance between laser spot and wire tip is 1 mm,the penetration of hybrid welding increase to 1.5 times which compared with conventional MAG welding,and hybrid welding can also improve spreadability,increase weld width,reduce undercut and so on.Hybrid welding,as laser welding,gets the maximal penetration,when laser focus was located 1 mm below the top surface of the plate. |
