摘要
大功率激光深熔焊以其优良的特性在制造行业中占有一席之地。本文利用微距高速摄影手段,对国产船用高强钢板激光深熔焊中的等离子体的作用进行实验研究,分析了保护气体流量、焊接速度、线能量对于等离子体面积和高度的影响,并综合分析了等离子体、线能量和焊接速度对焊缝熔深和熔宽的影响,总结了一些等离子体在焊接过程中的作用规律。
High power CO2 laser welding is now a potential technology in international shipbuilding industry. This paper focuses on a high-power laser welding of domestic ship plate experirnent to analyze plasma area and height with difference gas flow rate,welding speed and line energy. Then the relationship between the changes of plasma and geometry of weld has been researched. Finally this paper describes some disciplinarian of plasma effect in welding.
