May 10, 2022


Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is of thermal conduction type, that is, the surface of the workpiece is heated by laser radiation, and the surface heat diffuses to the interior through thermal conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully used in the precision welding of micro and small parts.


Compared with other welding technologies, laser welding has the following advantages:

1. Fast speed, large depth and small deformation.

2. It can weld refractory materials such as titanium, quartz, etc., and can weld different materials with good effect.

3. Micro welding can be carried out. After the laser beam is focused, a small spot can be obtained, and it can be precisely positioned, which can be applied to the group welding of micro and small workpieces in mass automatic production.

4. It can be welded at room temperature or under special conditions, and the welding equipment is simple. For example, when a laser passes through an electromagnetic field, the beam will not be deflected; the laser can perform welding in vacuum, air and certain gas environments.

5. After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the maximum can reach 10:1.

6. The laser beam is easy to realize the beam splitting according to time and space, and can carry out multi-beam simultaneous processing and multi-station processing for more precise welding.

7. It can weld hard-to-reach parts and implement non-contact long-distance welding, which has great flexibility.


Laser welding machine is to use laser welding technology to achieve various welding needs. The non-contact operation method can meet the requirements of cleanliness and environmental protection.Using handheld laser welding machine to process workpiece can improve work efficiency, finished workpiece has beautiful appearance, small welding seam, large welding depth and high welding quality.Laser welding machines are widely used in the processing of dental dentures, keyboard welding, silicon steel sheet welding, sensor welding, battery sealing cover welding and so on.
