Laser welding robot theory
Laser welding is to radiate a high - intensity laser beam to a metal surface. Through the interaction of the laser and the metal, the metal absorbs the laser and converts it into heat to melt the metal and then cool it to form a weld. According to the different laser output energy methods, laser welding can be divided into pulse laser welding and continuous laser welding (including high - frequency pulse continuous laser welding); laser welding can be divided into heat transfer welding according to the power density on the spot after laser focusing. Deep fusion welding; in laser deep penetration welding is divided into butt welding (brazing) and lap welding, the former needs to fill the brazing material, the appearance is beautiful.
Laser welding robot automation Solution
Since laser welding currently uses a solid - state laser as a light source, it is very easy to realize multiple optical path processing methods, which greatly improves production efficiency. Compared with CO2 laser machines, the efficiency of robotic laser welding systems is much higher than that of CO2 laser machines because CO2 lasers are difficult to achieve multiple optical paths. At present, there are several cases of robot laser welding systems replacing CO2 laser machine tools, and the welding efficiency is improved by more than 30%.
At present, some of the challenges in metal welding, such as the increasingly complex shape of the workpiece, the increasing quality of the welding, and the increasing number of orders in the individualized requirements of the processing, the robot laser welding system is completely used. Can meet these challenges. In recent years, new laser technologies such as fiber lasers and disk lasers have emerged, providing a unique condition for ABB laser-welded robotic workstations to challenge higher configurations.
