CO_2激光焊接铝合金工艺的研究

Study of Processing Parameters of CO_2 Laser Welding on Aluminum Alloys

在自己研制的5kW级横流CO2激光器上采用2～3kW低阶模功率输出,在20～120cm/min焊速下实现了1～4mm厚的6063型号铝合金的熔焊及对焊和1.5～4mm厚的LY12铝合金的对焊。

Fusion welding and butt welding of 6063 aluminum alloy (1~4 mm) and butt welding of LY12 aluminum alloy (1.5~4 mm) are realized by a home made 5 kW transverse flow CO 2 laser with 2~3 kW low order mode output and the welding speed ranged from 20 to 120 cm/min. The influence of processing parameters on weld quality are discussed.
