Laser welding has become a mature non-contact welding method for many years, high energy density makes high-speed processing and low heat input possible, high welding strength, narrow weld, small heat affected zone, and small deformation of the workpiece. Changing user needs and a high degree of international competition have caused the trend of changing to personalized needs in the field of sheet metal processing. For users, this means a greater degree of segmentation of the product line. Therefore, the need to produce a large number of the same parts is reduced, and the preparation time for each product is more and more. The whole processing process, especially the welding process, must adapt to this trend, and the appropriate equipment to meet this demand is the six-axis robot laser welding system.
laser welding
The physics of the laser was clearly articulated by Einstein in the early 20th century, however, the laser was not developed by the Hughes Institute in Malibu until 1960.
Four years later, the world came to power Nd:YAG solid-state laser and CO2 gas laser was developed, until today, these two lasers are two kinds of industrial lasers widely used in the world. In recent years, new laser technologies such as fiber lasers and disk lasers have emerged. The world's first laser welding for large-scale industrial production did not appear until 1984, 20 years later.
Today, laser welding has been widely used in various industries. In addition to laser welding, laser brazing, laser cold/hot wire feeding welding and laser hybrid welding have also greatly expanded the application field of laser.
Due to its unique flexibility and production efficiency, laser processing has become a unique process in various production links.
TOUKFly's robot laser welding system
The robot laser welding system model is TruLaser Robot 5020, based on a 6-axis robot, which has a very high flexibility, can complete the processing of complex workpieces, and can adapt to the changing situation of workpieces.
The robot welding system consists of the following components: KUKA robot, workbench, vacuum cleaner, laser light source and water chiller.
For laser light sources, pulsed lasers, diode lasers, fiber lasers, and disk lasers can all be connected to the robotic system.
