| 摘 要： | 针对Nd:YAG激光穿过GMAW电弧后,激光光斑会变小的现象,分别从GMAW电弧对Nd:YAG激光的吸收和折射两个角度进行了分析.结果表明,假设Nd:YAG激光状态改变全部由于GMAW电弧吸收现象造成时,脉冲GMAW电弧的吸收率为0.7%,短路GMAW电弧的吸收率为2.0%;假设Nd:YAG激光状态改变全部由于GMAW...

| Abstract: | From the view of GMAW arc''s absorption and refraction to Nd:YAG laser,the phenomena,which when Nd:YAG laser crosses GMAW arc,it''s radius will decreases,was analyzed in this paper.The results show that if decreasing of Nd:YAG laser radius is due to absorption of GMAW arc totally,the absorptivity of pulse GMAW arc to Nd:YAG laser is 0.7%,and the absorptivity of short-circuiting GMAW arc is 2.0%.If this phenomena is attributed to refraction of GMAW arc overall,Nd:YAG laser beam is deflected 0.34% by pulse GMAW arc,and 1.02% by short-circuiting GMAW arc.But considering this phenomena form the view of welding,it can regard approximatively GMAW arc as no effect on Nd:YAG laser beam transmitting. |
