1. Application case of laser wire filling welding of aluminum alloy top cover
The laser welding applied to the car body is mainly divided into two ways: one is fusion welding, which does not require filler material, and the laser directly acts on the surface of the workpiece for welding, which is mainly used in the structure of the side wall of the car, the door, the bottom plate, etc.; One is filler welding, commonly referred to as brazing, which is mainly used in structures such as top covers, tail covers, and flow troughs. So what kind of light source products can be used for filler welding? At present, Raycus high-power fiber lasers with shutters have been used by many automobile manufacturers in the related welding of the above automobile parts. The time-sharing shutter independently developed by Raycus has technical advantages such as stronger reliability and a coupling efficiency of more than 96%. The pluggable design can quickly repair faults, and at the same time, a laser can be used for cutting, welding, drilling and The function of cladding enables one machine to be used for multiple purposes, which can significantly reduce the user's investment cost in equipment and improve processing efficiency.

2. Application Cases of Tailored Welded Blanks for Automobiles
Laser Tailored Blank Technology is to first cut cold-rolled steel sheets of different or the same thickness, strength, and material into suitable sizes and shapes, and then laser weld them into an ideal whole, that is, laser tailored blanks. It has the advantages of reducing the number of workpieces, reducing the processing links, reducing the production cost, improving the quality of the workpiece, reducing the weight of the workpiece, and thus reducing the weight of the whole vehicle. Now almost all famous automobile manufacturers have used a large number of laser tailor welded blanks in automobile production. And suppliers of tailor-made blanks for automakers have emerged. The C4000XZ/C6000XZ/C6000H developed by Raycus Laser can be better applied to the application of tailor welded blanks for automobiles.
3. Application case of laser cutting of automotive thermoforming sheet
The strength of the car body depends to a large extent on the design of the body and the strength of the steel plate, so the strength of the steel plate in the important protective parts of the body is particularly important. The hot forming steel plate technology refers to that the steel plate is heated at a high temperature of nearly 1000 degrees Celsius and then formed once, and then rapidly cooled to comprehensively improve the strength of the steel plate. This kind of material is used in the car body, and the bearing capacity is increased by 30% under the condition that the weight of the car body does not change much, so that the rigidity of the car reaches a new level, and the safety of the car is also improved. In the process of automobile production and manufacturing, the cutting of thermoforming plates is inevitably involved. It is recommended to use Raycus' third-generation single-module continuous fiber laser C4000S. It has the characteristics of non-contact processing, high precision cutting quality, good efficiency, good flexibility and no need for secondary processing.

4.the application case of laser cleaning of aluminum alloy side walls
Generally, before laser welding of automotive aluminum alloy sheet, it needs to be pre-cleaned. The use of Raycus 500W automatic laser cleaning system can effectively remove pollutants such as oxide layer and grease on the surface of aluminum alloy, significantly reduce black ash after welding and internal pores in the weld, improve the strength and elongation of welded joints, and strengthen welding uniformity , improve the welding quality. At present, the cleaning solution has been used in a well-known foreign automobile production line.
RFL-P500H
Features:
Universal control interface, strong compatibility
The working frequency is adjustable
High single pulse energy
High beam homogenization
Product application: car roof cleaning/aluminum alloy side wall cleaning
5. Application case of VIN laser coding on frame
Using the traditional mechanical scribing method to carry out the VIN laser coding of the car frame, there will be problems that the scribing head is damaged or cannot be scribbled. The laser has the characteristics of good flexibility, non-contact processing, reduced tool wear, reduced production cost, strong stability and consistency, and can meet the processing and use of ultra-high-strength materials. Using Raycus QCW300 fiber laser, the deep engraving of high-strength steel can reach 0.3mm, and it can be completed within 20s.
QCW300/3000
Features:
Available in both continuous and pulsed modes
Peak power up to 3000W
Extremely stable output performance
Excellent beam quality
QBH output header, output length optional
Air-cooled/water-cooled cooling products
Product application: VIN coding of seat beam / coding of engine cylinder head
Lasers are widely used in the field of automotive intelligent manufacturing. In addition to the above body applications, it also involves automotive lamp plastics, airbag igniters, triggers, fuel injectors, automotive air conditioners, cigarette lighters, steering gears, sensors and other components Applications.
In the future, with the continuous development and maturity of laser application technology in various industries, the application fields related to automobiles and parts are also gradually being developed. Raycus Laser will adhere to the road of technological innovation, play a leading role in the industry, and continue to provide more excellent and reliable products for the automotive industry.
