Laser welding technology is to focus the laser energy on a beam, and then processed into a weld on the workpiece, laser welding mainly includes laser welding host, laser welding head, cable, cooling system. Laser welding machine includes CO2 laser, fiber laser, disc YAG laser, semiconductor laser and so on.

Laser welding is a new type of welding technology with optical properties such as refraction and focusing. In addition, laser welding also has the advantages of low heat input, low deformation and not affected by strong electromagnetic field. With the progress of The Times and the continuous development of laser technology, many companies and individuals have given up the traditional processing methods and turned to laser technology. Next, we will introduce the advantages of laser welding in detail:

1. Micro-machining after welding

2. Welding speed is fast. In order to improve production efficiency, some manufacturers win by quantity, which is a great advantage

3. Constant temperature output

4. Reduce rework, increase productivity and reduce costs, killing two birds with one stone

5. Improve the appearance and welding quality of welding pass

6. Improve automation to achieve full automatic without manual operation

In the traditional welding, often occur deformation, hardness reduction, trachole, crack, pinhole, abrasion, binding force can not reach the internal stress damage. The laser weld is the use of intelligent welding seam tracking technology, the use of non-contact tracking technology, to solve the weld defects due to the workpiece position deviation, thermal deformation and other reasons, so as to improve the productivity and product quality, the welding speed is 5-10 times faster than the traditional welding machine.

Application of laser welding in new energy vehicles

The automobile is a kind of life necessity which has entered into millions of households, and the new technology it uses reflects its quality to some extent. The application of laser in the field of automobile, mainly include the welding of car frame parts, automobile battery welding and so on. The laser welding technology of traditional fuel vehicle has been widely used in our country, but it is still rare in the production line of electric vehicle. In the aspects of frame and inside the car, the laser technology will imitate the technology of fuel vehicle, and gradually expand the use of laser. By 2022. The sales volume of electric vehicles in China is expected to exceed 3 million units, and the mass production of laser products will become an inevitable trend in the future. Laser trend car body is widely used with the power of 4 kW, 6 kW laser, which puts forward new requirements for high power automatic laser welding. Xindel Laser has laser welding equipment ranging from 1500 watts to 6000 kW, which can serve the new energy automobile industry well.
