使用所建立的有限元模型,分别对激光焊接功率在1～5kW,焊接速度在0.3～1.5m/min情况下进行了模拟,分别得到了激光功率与熔深、熔宽的关系和焊接速度与熔深、熔宽的关系。可作为铝合金激光焊接工艺指导。
Using the established finite element model, the laser welding power is 1 ~ 5kW and the welding speed is 0.3 ~ 1.5m / min respectively. The relationship between laser power and penetration depth and welding speed are obtained Penetration, melting width of the relationship. Aluminum laser welding process can be used as a guide.
