What are the advantages of laser welding machines compared with traditional welding?

Laser welding machine is a kind of machine used in the field of welding and is one of the important aspects of the laser material processing technology application. The welding machine technology used for welding is not a long time, but the development is quite rapid. The main reason is that this technology is quite compatible with industrial production, it also adapts to the requirements of industrial production, so in the future, the application of laser welding machine technology will be more in welding industry.

Laser welding machine is divided into nanosecond pulse laser welding machine, QCW laser welding machine and YAG laser welding machine according to its working mode. So, what are the advantages of laser welding machine compared with other welding techniques?

1. High flexibility
Laser welding technology is the most advanced welding method in the field of processing. Compared with traditional welding technology, laser welding technology is non-contact welding, the operation process does not require pressure, the welding has fast speed, high efficiency, large depth, little residual stress and deformation. The welding on different materials has good effect and great flexibility.
2. It can weld hard-to-weld materials
Laser welding uses laser beam with extremely high energy density to melt material. The laser welding machine has fast welding speed, narrow weld seam, high strength, small heat affected zone, and little deformation on the workpiece with less subsequent processing work.
3. Less labor costs
Since laser welding has extremely low heat input, the amount of deformation after welding is very small, and the surface welding effect is very beautiful, so the laser welding has few subsequent processes, which can greatly reduce or save manual labor on the huge polishing and leveling process.


The laser welding machine developed by Shenzhen Sun Laser Technology Co., Ltd., combined with computer technology, is mainly for micro-welding on thin-walled materials and precision parts, it can implement spot welding, butt welding, stitch welding and sealing welding. It has fast welding speed, smooth and beautiful weld seam, no need further process or only simple process is needed after welding. And it can perform flexible transmission non-contact welding on the inaccessible parts, the laser beam enables time and energy splitting, multiple beams can process simultaneously, which provides conditions for more precise welding.
