What are the advantages of laser welding machine application in the automotive industry?

China's laser welding is at the world's advanced level. It has the technology and ability to use laser to form complex titanium alloy components of more than 12 square meters, and has invested in the prototype and product manufacturing of multiple domestic aviation scientific research projects. Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology.

The machinery industry is developing rapidly, and equipment industrialization and chain-based manufacturing have been realized in many fields. The equipment category has been gradually improved, the reliability and automation level have been greatly improved, and the automobile has also entered every household from luxury goods. Lixing Laser focuses on the exploration and breakthroughs of laser welding technology for automobile panels, and has accumulated rich experience in automobile four doors and two covers, sunroofs, door sills, automobile pillars, automobile doors, automobile flow troughs, automobile side walls, automobile water tank brackets, etc. Welding application experience and development of many leading process technologies.

So, what are the advantages of laser welding machine application in the automotive industry?

Analysis of the advantages of laser welding machine in the automotive industry:

The laser welding production line has appeared in the automobile manufacturing industry on a large scale and has become one of the outstanding achievements of the automobile manufacturing industry. European automobile manufacturers such as Audi, Mercedes-Benz, Volkswagen and Volvo of Sweden took the lead in adopting laser welding for roof, body, side frames and other sheet metal welding as early as the 1980s.

The laser welding machine is applied to the laser welding of galvanized sheet, which meets the high requirements of the galvanized sheet cover for the laser welding process and fixtures, and effectively assists the high-speed, stable, high-quality, and lightweight production of automobile equipment. According to the characteristics of large batches and high degree of automation in the automotive industry, laser welding equipment is developing in the direction of high-power and multi-channel.

Automobile covering parts have the characteristics of large number of welds, dense welds, high safety performance requirements, and base metal of galvanized sheet. Laser welding equipment mostly uses laser remote static welding and laser flying welding technology, and its welding efficiency is higher than that of traditional laser welding. 4 times, and the welding heat input is small and the requirements are high.

The laser welding machine is applied to automobile sheet metal parts and transmission parts. It has a wealth of application cases and professional technology, including automobile gears, flywheels, pistons, shift forks, differentials, shock absorbers, turbochargers, fuel tanks, and airbags. And other auto parts provide equipment and related laser welding technology. At the same time, laser tailored welding technology has realized the welding of nearly 20 steel plates of varying thickness in the automotive industry, which has greatly contributed to the lightweight production of the automotive industry.

The laser welding machine is used in laser welding of aluminum alloy. The welding speed is very high and the input of small heat can be effectively controlled to obtain high-quality workpieces. At present, aluminum alloy laser welding technology has been successfully applied to the manufacture of battery trays, roof and side panels, trunk back covers, engine inner covers, door welding, door inner panel assemblies and other automotive parts. Among them, the aluminum alloy door laser welding workstation uses 5 series aluminum alloy as the processing material, which can realize 3mm+3mm overlap welding, and uses laser swing welding in the laser welding process. After welding, the aluminum alloy door deforms little, and the weld seam is beautiful. flawless.
