Laser handheld welding is so popular, do you know these characteristics?
Laser welding is an efficient and precise welding method that uses a high-energy density laser beam as a heat source. It is one of the important aspects of laser material processing technology applications.
Compared with other welding technologies, the main advantages of laser welding are:
1. Fast speed, large depth and small deformation.
2. It can be welded at room temperature or under special conditions, and the welding equipment is simple. For example, when the laser passes through an electromagnetic field, the beam will not shift; the laser can be welded in vacuum, air and certain gas environments, and can be welded through glass or materials that are transparent to the beam.
3. It can weld refractory materials such as titanium, quartz, etc., and can weld heterogeneous materials with good results.
4. After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1, and the highest can reach 10:1.
5. Micro welding is possible. After the laser beam is focused, a small spot can be obtained, and it can be accurately positioned, which can be used in the assembly welding of micro and small workpieces that are automatically produced in large quantities.
6. It can weld hard-to-access parts, and implement non-contact long-distance welding, which has great flexibility. Especially in recent years, the use of optical fiber transmission technology in YAG laser processing technology has made laser welding technology more widely promoted and applied.
7. The laser beam is easy to realize the beam splitting according to time and space, and can perform multi-beam simultaneous processing and multi-station processing, which provides conditions for more precise welding.
In recent years, laser welding has been optimistic, but the market demand has not developed significantly. Until a few years ago, the explosive growth of new energy vehicles in China, the large-scale expansion of power batteries also led to the growth of laser welding. Hand-held laser welding has gradually been welcomed by more people and has become a bright spot in the laser welding market.
Features and advantages of handheld laser welding machine:
1. The welding gun of the handheld laser welding machine replaces the traditional fixed light path, which is more flexible and convenient, realizes long-distance laser welding, and overcomes the limitation of the workbench stroke space;
2. The hand-held welding head is light and flexible, convenient and easy to operate, and meets the welding of various angles and positions; it can complete the welding of arbitrary parts of the workpiece with arbitrary viewpoints, which is sensitive and convenient, can complete outdoor welding, and is suitable for various messy welding seams. Spot welding of various equipment.
3. The handheld welding head is equipped with 5 meters of imported optical fiber, which is flexible and convenient to realize outdoor welding. The workpiece can be welded at any angle, the dual optical paths are intelligently switched, and the energy distribution of time-sharing and light-sharing is even.
4. The handheld laser welding machine adopts infrared positioning, which is used for welding head position proofing and position verification during welding. The welding position is more accurate and the welding seam is more beautiful.
5. Low maintenance cost: handheld laser welding, no fine welding table, low material, low energy consumption, low equipment deployment and maintenance costs. In the same working environment, we need to spend a lot of time to maintain the welding table, and the manual laser setup equipment deployment can work as long as it is equipped with handheld laser welding. In terms of replacement, the cost of accessories is low.
