Since the early 1980s, the automotive industry has been one of the main drivers of the high-power laser industry. In the field of cutting, welding and marking, laser technology can bring greater benefits than the traditional manufacturing technology to meet the core requirements of the entire industry. So what are the applications of laser technology in automobiles?
Laser Welding
The use of laser technology welding, its advantages are extremely high welding speed, stable welding quality, high welding precision, small thermal deformation of materials, and easy to integrate into the automation operating system, which is widely used in modern industrial production, with excellent reputation. Advanced welding method. Laser welding has been widely used in automobiles, such as welding of automobile bodies, pipe welding, automotive battery welding, and plastic welding of instrument panels. Lasers have unique advantages in terms of welding strength, welding precision and speed.
Laser Cutting
Laser cutting is also one of the most frequently used laser applications. Fiber lasers and CO2 lasers can be combined with standardized 2D and 3D cutting systems to cut low carbon steel, stainless steel, aluminum and other metals. When processing different parts of a car, automakers take advantage of the advantages of laser cutting, such as high cutting edge quality, low heat input, and fast processing speed. Automotive parts and materials, including a variety of metals, such as airbag fabrics and composite materials used in automotive interiors, are cut using a laser.
Laser Surface Treatment
In addition to traditional processes such as laser cutting and laser welding, lasers can also be used in a variety of surface treatment applications such as laser hardening, laser de-layering, surface activation, and laser surfacing. The automotive processing industry usually uses powder for laser surfacing, which can be used as a protective film for workpieces to prevent wear and corrosion, as well as high temperature and corrosion resistance (liquid). Laser surfacing with filler wire can be used to repair workpieces, improve material wear resistance, achieve small design improvements, and correct manufacturing defects.
