Laser welding machine application on car bumper

We know that the front and rear ends of the car are equipped with bumpers, which not only have decorative functions, but also are safety devices that absorb and mitigate external impact forces, protect the safety of car, driver and occupant.

With the development of the automotive industry, car bumpers have also taken a new path as an important safety device. At present, in addition to maintaining the original protection function, the front and rear bumpers of the car also pursue harmony and unity with the shape of the car body. However, the car bumper welding by traditional welding method is not strong, and it is prone to crack, leakage, deformation, etc., which greatly reduces the overall appearance of the automobile.

Welding a car bumper by laser welder perfectly solves these problems. The Laser welding machine uses high-energy laser pulse to locally heat the material in a small area. The energy of the laser diffuses into the interior of the material through heat conduction, and the material is melted to form a specific molten pool for welding purpose.

The car bumper laser welding machine has small heat-affected zone, little deformation, fast welding speed, smooth and beautiful weld seam, no need further treatment after welding or only  simple treatment is needed, high weld quality and no porosity. Compared with traditional welding methods, the car bumper welded by the laser welding machine is firm and beautiful, and the non-contact welding method will not deform the product.

Shenzhen Sunlaser Technology Co., Ltd. is a high-tech company integrating R&D, production, sales and service of laser equipment. The laser welding machine mainly focuses on the welding of thin-walled materials and precision parts, and can implement spot welding, butt welding, stitch welding and sealing welding.
