威廉希尔官方下载Jan 06, 2020

In the manufacture of automobiles and parts, some common welding methods include resistance welding, arc welding, laser welding, and ultrasonic welding. The welding effect and application of different welding methods also have certain differences. The laser welding machine welding process can accurately weld the weld, which can effectively combine the molecular layers of the weld and achieve seamless butt welding. .


The seamless welding of the laser welding machine has greatly improved the structural precision of the car body. When the car is driving, due to the bumps of the ground, every component and structure is subjected to different degrees of impact. This requires the overall structural precision of the car to be very high. With the current laser welding technology, its dynamic and static stiffness can be improved by more than 50% compared with other welding processes, which reduces noise and vibration during driving, improves riding comfort, and also improves the safety performance of the car.

威廉希尔官方下载The laser welding machine adopts seamless welding on the body, which is stronger than spot welding to a certain extent and has relatively high safety. Because the laser welding machine technology uses a polarizing mirror to reflect the laser beam and focus it on the focusing device, which generates a huge energy beam. If the laser beam is close to the component, the component will melt and evaporate in a few milliseconds One technique can be used in the welding process. The laser welding machine is characterized by small deformation of the welded parts, almost no gap after welding, and higher welding quality than traditional welding methods.


威廉希尔官方下载Laser welding is different from the traditional welding process. Laser welding can achieve molecular bonding between two steel plates, that is, after welding, it can become a whole steel plate with comparable hardness, which effectively improves the compressive strength of the car. The whole automobile structure is linked into a whole, and the energy can be carried to the ultra-high-strength hot-formed steel sheet during the impact.


In the manufacture of automobiles, high precision, small deformation, low thermal impact, high weld quality, no solder required, and efficient welding speed and welding quality ensure low cost operation and unrestricted high feasibility. The industry has achieved tailor welding, overlay welding, body welding and parts welding of auto parts.


Laser welding of auto parts can reduce the number of parts and molds, reduce the number of spot welding, optimize the amount of materials, reduce the weight of parts, reduce costs and improve dimensional accuracy. The strength of steel plates after laser welding will increase by more than 30%; The width of the joint surface can be reduced, the use of sheet material is reduced, and the rigidity of the car body is improved; the welding parts of the automobile parts are free of deformation, the welding speed is fast, and the welding machine does not require heat treatment, and has strong flexibility. Realized the advantages of small deformation, high weld strength and fast speed.
