Analysis of Advantages of Laser Precision Welding INSHINE LIGHTING CO.,LTD , https://www.inshinelight.com
In the field of welding, the common types of precision welding include precision resistance welding, laser welding, ultrasonic welding, and micro arc spot welding. Due to the characteristics of the laser itself, the precision laser welding process has the advantages of high efficiency, environmental protection and high processing precision compared with other welding processes. It represents the direction of precision welding processing.
With the development of welding processing, its prospects are very broad. Let us first talk about its advantages:
1) It is possible to weld a variety of tracks. The laser has a strong directivity, which also has a good effect on the welding of irregular materials;
2) The welding is firm. After the laser is focused, the spot size is small and the energy density is high, which ensures that the beam forms a heat source area in a short time, and forms a strong weld seam and solder joint after melting and cooling crystallization;
3) High welding precision. The distribution of laser energy is characterized by time and space. The beam can be divided into multiple optical paths for simultaneous processing operations. A strong guarantee for the accuracy of the welding;
4) Welding speed is fast. Laser technology is combined with microcomputer CNC technology. In terms of equipment critical detection and motion control systems, system integration with real-time detection and feedback processing speeds up system information processing and improves welding efficiency.
However, everything has advantages and disadvantages. After talking about the advantages, let's talk about its shortcomings:
a) the welding penetration is small;
b) poor performance of welded joints;
c) the cost of consumables required for the equipment is higher;
With the continuous development of laser technology, in view of the shortcomings of precision laser welding, people adopt new schemes to improve the heating of the workpiece by laser, and use laser hybrid welding (such as laser and plasma arc welding, double laser beam welding) to improve The performance of the laser welded joint reduces the cost of the equipment.
