With the rapid development of society, the requirements of various industries for the welding process of products are getting higher and higher. The traditional welding technology has unstable welding quality, which is easy to cause parts to melt, difficult to form normal nugget, and low welding yield, which often causes manufacturers to have a headache. The emergence of laser welding machine technology has played a major role in the volume optimization and quality improvement of the product. Because it belongs to non-contact processing, the heat impact is small, the processing area is small, the mode is flexible, and the demand in the market is also growing. Let us look at the application areas of laser welding machines?
1. Manufacturing applications
Laser welding machines are widely used in automobile manufacturing at home and abroad. In Japan, CO2 laser welding machine was used instead of flash butt welding for the steel industry rolling steel coil connection. In the research of ultra-thin board welding, such as foil with a thickness of less than 100 microns, there is no way to weld, but through YAG laser welding with a special output power waveform has been successful, showing the broad future of laser welding.
2. Powder metallurgy field
Science and technology are constantly evolving. Many industrial technologies have special requirements for materials. Materials made by traditional technologies cannot meet the requirements. The laser welding machine enters the field of powder metallurgy material processing, which brings new development prospects for the application of powder metallurgy materials. For example, the welding method is commonly used in the brazing method of powder metallurgy material connection because the bonding strength is low and the heat affected zone width is especially It is unable to adapt to the high temperature and high strength requirements, causing the solder to melt and fall off. The laser welding machine can improve the welding strength and high temperature resistance.
3. Electronic industry
Laser welding machines are widely used in the electronics industry. Because the laser welding heat affected zone is small, the heating concentration is rapid, and the thermal stress is low, it is showing unique advantages in the packaging of integrated circuits and semiconductor device casings. In the development of vacuum devices, laser welding has also been applied. The thickness of the elastic thin-wall corrugated sheet in the sensor or the thermostat is 0.05-0.1mm, which is difficult to solve by the traditional welding method. The TIG welding is easy to weld, the plasma stability is not good, and the influence factors are many, and the laser welding effect is good. Widely used.
4. Automotive industry
Nowadays, the laser welding machine production line has appeared on the large scale in the automobile manufacturing industry and has become one of the outstanding achievements of the automobile manufacturing industry. Many automotive manufacturers use laser welding and cutting processes. High-strength steel laser welding fittings are used more and more in the manufacture of automobile bodies due to their excellent performance. Because of the large volume and high degree of automation in the automotive industry, laser welding equipment will develop in the direction of high power and multi-path.
