With the rapid development of laser application technology, more and more fields are involved. Like other technologies, lasers are also closely combined with computers, automation and other technologies, and develop together quickly. With the increasing of industrial demand, the galvanometer welding technology from a two-dimensional system to a three-dimensional system is the only way for technological development. A 3D laser welding system with high reliability and comprehensive functions is one of the basic technologies to ensure that the laser welding system is put into use.
Laser scanning galvanometer welding technology combines the advantages of laser welding technology. First, the welding speed is fast. The galvanometer scanning can accurately locate the welding point, which can shorten the processing time, and also has the advantage of starting and stopping at the same time. The second is small stress and deformation. The welding laser has a very low power density on the surface of the workpiece, which can quickly melt the material of the parent part, avoiding the deformation of the workpiece due to the heat of the welding transmission. The third is the weldable refractory materials. Laser galvanometer welding is mainly controlled by a computer control system, which can weld workpiece that are difficult to weld manually by automatic welding.
Core application——SINO-GALVO 3D laser scanning galvanometer welding system
On the basis of the original two-dimensional (X, Y-axis) galvanometer welding system, SINO-GALVO’s 3D laser scanning galvanometer welding system adds the function of dynamic focusing laser. The dynamic focusing part is habitually called the Z axis, and the dynamic focusing galvanometer laser welding system is also habitually called the three-dimensional galvanometer welding system.
The hardware equipment for three-dimensional welding mainly includes fiber lasers and three-dimensional galvanometer systems.
The workflow of the three-dimensional laser scanning galvanometer welding system is shown in the following figure:
Comparing the three-dimensional laser scanning galvanometer system with the X-Y plane laser scanning system, it can be found that the three-dimensional laser scanning galvanometer system has obvious advantages:
● High scanning speed : the laser can be moved in a large range through the small angle deflection of the galvanometer;
● High positioning accuracy: the use of position sensors and the design ideas of the negative feedback loop ensure the accuracy of the system;
● Small noise: almost no sound when the galvanometer rotates;
● Not In direct contact with the working environment, the entire system can be located outside the processing substance.
● Large focal length variable range, can continuously and quickly complete the welding of 3D products.
With the advent of the era of galvanometer, Laser scanning in China has once again ushered in a leaping-forward development, and the great improvement in speed and accuracy has once again stimulated the original tool industry. At the same time, the market of the industry that could not be processed by laser was also widely opened due to the high requirement for accuracy.Two-dimensional welding can no longer meet the current market demand, the era of three-dimensional galvanometer welding system has arrived.
