In recent years, high-power lasers have become an important driving force in the automotive manufacturing industry. Compared with traditional processing technology, laser has obvious advantages in cutting, welding, marking and other aspects. Because laser technology is more flexible and easy to automate than conventional technologies, it can meet the core requirements of the entire industry.
- Laser welding
Laser welding has the characteristics of high energy density, small deformation, small heat influence range, fast welding speed and convenient automatic control, which is an important way for the development of the automobile industry. Using laser welding technology, metal materials of different thicknesses, grades, varieties and grades can be seamlessly docked, which not only improves the manufacturing efficiency of products, but also improves the quality of products, and provides more choices for the design and selection of vehicles. Laser welding is simple and fast to operate, and high-quality, high-strength welds can be obtained without the use of welding wire; And it has a large aspect ratio and high welding quality, which is not only bright and beautiful, but also has high accuracy, good repeatability and high yield; In addition to this, the process has a high welding rate and a low thermal conductivity, which can effectively reduce thermal distortion.
- Laser marking
Laser marking is a marking method that uses a high energy density laser to irradiate the workpiece locally, so that the surface material vaporizes or undergoes a chemical reaction of color change, so as to leave a permanent mark. Laser marking has a non-contact marking capability that allows marking on any shaped surface without deforming the workpiece, without causing internal stress, and also eliminating chemical and noise contamination. Laser marking technology is permanent, and the mark will not fade due to changes in time, environment and other elements. It is highly adaptable and capable of marking most metallic or non-metallic materials with extremely fine marking. Laser marking is fast and consumes less energy.
- Laser cutting
Laser cutting is one of the most commonly used laser processing methods, and the types of laser cutting are divided into four categories: laser vapor cutting, laser melting cutting, laser oxygen cutting, and laser dicing and controlled fracture. Laser cutting has the advantages of narrow incision width, small heat-affected zone, smooth incision, fast cutting speed and strong flexibility. In addition, it is non-contact processing, and there is no need to apply mechanical force to the workpiece, and the workpiece is not easy to deform.
