Background
Laser brazing is widely applied to the field of modern automobile body welding, particularly to the connection of body-in-white steel plates, however, when laser brazing is used for connecting hot-dip galvanized steel plates with better corrosion resistance, ideal welding effect cannot be achieved due to fine splashing of a zinc coating. For this reason, laser manufacturers have developed a laser brazing process for removing the zinc coating in advance, which is called a multi-spot system, and the process generally removes the zinc coating around the weld using an ablation spot with a small power and then welds the weld using a main spot, and the process can significantly improve the spattering phenomenon during welding without reducing the welding speed and improve the welding quality.
However, in order to achieve a better welding effect, the multi-spot system must ensure the precise layout of the ablation spots, however, a laser brazing welding head is usually integrated with an industrial robot to achieve automatic welding, and in actual production, it is found that when a large 360-degree annular long welding seam such as an automobile battery pack cover plate is welded, the precision and accessibility of the path and the action of the industrial robot are limited, so that the angle of the brazing laser head has to be deflected, the multi-spot system cannot work normally, and the welding quality is difficult to ensure.
