    摘要

    激光焊工艺能量密度高、精度高、热影响区和焊接变形小,适用于汽车精密零部件的焊接。针对座椅调角器与3 mm厚连接板的连接,采用激光穿透焊替代电弧焊,结构上无需预留工艺开口,产品设计更加柔性化;调整激光焊接的工艺参数,分析各工艺参数对焊接质量的影响,当激光功率为2 200 W、焊接速度为20 mm/s、负离焦量为5 mm时,可获得较好的焊缝外观质量,在满足多条焊缝紧密布置的同时,其焊接熔深达到3.9 mm以上。

    Abstract

    The advantages of laser welding process include high energy density, high precision,small heat affected zone and welding deformation,which is especially suitable for the welding of automobile precision parts. Laser penetration welding is used instead of arc welding to connect recliner assy and 3 mm thick connecting plate,meanwhile,there is no need to reserve process opening on the parts and the product design is more flexible. The influence of each process parameter on the welding quality is analyzed by adjusting the laser welding parameters. When the welding parameters are designed as laser power of 2 200 W,welding speed of 20 mm/s and negative defocusing amount of5 mm,the appearance of weld is good,and multiple welds are closely arranged and the penetration is over 3.9 mm.
