| 摘 要： | 为了进一步了解激光-电弧复合焊接机理及其影响因素,采用A3钢进行了CO2激光-脉冲金属熔化极活性气体保护焊(MAG)电弧复合焊接的工艺研究。分析了CO2激光-脉冲MAG电弧复合焊接中焊接方向、热源间距、激光功率、电弧电流、焊接速度等工艺参数的影响。结果表明,采用适当的参数,激光电弧的能量能够有效耦合,增强焊接效果。其中,复合焊接熔深是单独激光的1.6倍、MAG电弧焊接的2.2倍;焊接速度是单独激光的2.7倍。

| Abstract: | In order to understand the mechanism and effect factors of laser-arc hybrid welding,hybrid welding combining CO_2 laser and pulsed metal active gas(MAG) arc are taken to weld mild steels,and the effect of various parameters on the welding penetration depth and quality is studied.Laser and arc can be coupled to enhance welding quality if using suitable parameters.Compared with laser welding and MAG welding respectively,hybrid welding penetration can be increased by 1.6 and 2.2 times,while hybrid welding speed can increase 2.7 times that of laser welding. |
