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

Laser processing technology is a technology that uses the characteristics of the interaction between laser beams and substances to cut, weld, surface treat, punch, micro-machine materials (including metals and non-metals), and use them as light sources to identify objects, etc. The traditional application is the largest. The field is laser processing technology. Laser processing has many advantages such as low thermal impact and minimal material deformation.

The automobile industry is an industry with a high concentration of high-tech. In developed industrial countries in Europe and the United States, 50% to 70% of auto parts are completed by laser processing, mainly laser welding and laser cutting.

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

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

1. Laser cutting machine is used in the automotive industry

Laser cutting machines are mainly used in the cutting of high-strength steel body frames. For some high-strength steel structural components with complex contours, mechanical stamping methods have reached their limits, both from a technical point of view and from an economic point of view. Very effective processing means.

The laser cutting machine can double the efficiency of cutting automobile shift sleeves, and the cutting quality is better than that of traditional processing methods. The end face is smooth, the positioning is accurate and the precision is high. The car bumper is a special-shaped part. The traditional stamping method is very complicated, and the parts are prone to deformation and stress. The laser cutting method does not require a complex fixture system, no processing stress, and no deformation of the incision, which is more suitable for post-processing and installation.

2. Laser welding machines are used in the automotive industry

Laser welding machine is used for body roof welding. Laser welding can achieve molecular bonding between two steel plates and increase the strength of the body by 30%. Compared with traditional welding, it can compress the volume of the body structure itself, thereby reducing the weight of the body.

We all know that most of the steel plates used in automobiles are galvanized steel plates, and the resistance welding process will damage the galvanized protective layer, making the damaged galvanized layer area easy to rust. Laser welding can ensure qualified weld formation and meet the requirements of corrosion resistance, high strength and fatigue resistance. The laser welding seam is very narrow and the heat-affected zone is very small. Through the long-range sacrificial effect of zinc, the weld can not be corroded for a long time. The faster the welding speed, the higher the hardness of the weld.

The laser welding machine is used for the welding of automobile airbag liner. Since the automobile airbag liner is equipped with gunpowder, the laser welding method is adopted, and the heat affected area is small, which can improve the safety and reliability in the processing process, and at the same time improve the production efficiency and improve the welding quality. question.

Laser welding machine is used for automobile gear welding, which can improve the product precision of transmission gears, make the gear parts compact, improve the precision and reliability, reduce the vehicle failure rate, improve the vehicle handling flexibility, and improve the product reputation.

The laser welding machine is used for welding the trunk of the car. The trunk is composed of a trunk lid and a rear panel. Since the forming has a 90° angle, the laser brazing filler wire is used for fillet welding. Laser wire filler welding is mainly used for welding with complex welding formation or sharp change in the tangential direction of the weld. The surface of the welding formation is smooth, and it is difficult to form a smooth weld.

The above is the analysis of the advantages of laser cutting machine/laser welding machine in the automotive industry. Laser cutting machine/laser welding machine is used in sheet metal processing, chassis cabinets, lighting, machining and hardware industries.
