In recent years, in order to encourage the development of the new energy vehicle industry, the state has issued a series of policies, of which the most influential one is the "Financial Policy on the Promotion and Application of New Energy Vehicles in 2016-2020" jointly issued by the Ministry of Finance and other four ministries and commissions in 2015. Notice of Support Policy.

 

In recent years, in order to encourage the development of the new energy vehicle industry, the state has issued a series of policies, of which the most influential one is the "Financial Policy on the Promotion and Application of New Energy Vehicles in 2016-2020" jointly issued by the Ministry of Finance and other four ministries and commissions in 2015. Notice of Support Policy. The "Notice" clearly states that the central government will provide subsidies for the purchase of new energy vehicles and implement the Generalized System of Preferences. Consumers can purchase models that have entered the national recommended catalogue at the price after deduction of subsidies. With the continuous development of new energy vehicles, the state has successively reduced subsidies for new energy vehicles. In recent years, thanks to the growing consumer demand for new energy vehicles, many new technologies and new materials have been continuously developed for use in new energy vehicles. The manufacturing process of new energy vehicles. Among them, laser technology is a very important technology. The application of laser technology in the new energy vehicle industry is mainly reflected in three aspects: one is laser cutting, the other is laser welding, and the third is laser marking.

 

1. Laser cutting

Laser cutting in the automotive industry includes flat sheet laser cutting and three-dimensional laser cutting. Covering all aspects of auto parts, auto body, auto door frame, car trunk, car roof cover and so on. The application of 3D laser cutting technology in the automobile manufacturing industry is mainly in the design and manufacture of automobile bodies. Cut steering wheel holes, windshields, roof brackets, etc.

2. Laser welding

Laser welding technology has been widely recognized and adopted internationally, especially in the automotive industry, where it develops the fastest. The development of the new energy automobile industry in the past two years has led to the application of lasers in tailor-welded blank welding, automobile body-in-white welding, power battery welding, gearbox gear welding, airbag liner welding, bumper welding, etc. Welding equipment companies have brought huge dividends and also promoted the development of automation, flexibility and intelligence in my country's auto industry.

3. Laser marking

In terms of automotive marking, there are several types of mold casting, electro-corrosion marking, self-adhesive, screen printing, pneumatic marking and laser marking in the market. Among them, laser marking technology was born the latest, but laser marking relies on traditional processing. The incomparable advantage of this method is that it does not need to contact the surface of the processed item, and can mark any special-shaped surface material, and the workpiece will not deform and generate internal stress. It is gradually being recognized by more and more car manufacturers.

Even though the subsidy policy for new energy vehicles has declined in 2019, after several years of development, the new energy vehicle manufacturing industry is undergoing technological upgrades, industrial changes and manufacturing upgrades. The combination of advanced laser processing technology and automotive automation has become a With the general trend, it is foreseeable that the application prospects of laser technology in the new energy vehicle manufacturing industry will become more and more broad.
