摘要
揭示了激光-电弧复合热源焊接过程中GMAW电弧对Nd∶YAG激光的吸收作用,对深入分析激光和电弧的耦合机制具有重要意义.通过保持脉冲GMAW电弧正常态,Nd∶YAG激光水平逐层、逐点扫描穿过脉冲电弧区域的试验方式,获得了Nd∶YAG激光穿过脉冲GMAW电弧后的能量损失情况.结果表明,波长为1.064μm的Nd∶YAG激光穿过保护气成分为Ar/CO2=80/20的脉冲GMAW电弧的任何区域都几乎不损失能量,波长为1.064μm的Nd∶YAG激光穿过不同电流强度的脉冲GMAW电弧也几乎不损失能量.
The absorption of GMAW arc to Nd:YAG with wave length 1.064 μm was invested,which is helpful to analyze hybrid mechanism between Nd:YAG laser and GMAW arc.By keeping GMAW arc normal position and Nd:YAG laser parallel crossing GMAW arc,laser power loss during passing GMAW arc was measured.The results indicate that there is almost no power loss when Nd:YAG laser passed though pulse GMAW arc.
