SHINHOP laser

The automotive industry is certainly in an era of rapid development, especially with the widespread promotion and application of new energy vehicles. The replacement of old and new car models promotes further advancement in automotive technology. In terms of laser welding technology, laser welding equipment closely related to power batteries and automotive component welding technology provides good protection for automotive safety technology. Here, we provide several automotive welding technology solutions for your reference and learning!
1. Overall automated laser welding system equipment for white car roofs
This type of welding system has high welding accuracy and good quality, can automatically identify various vehicle models, and can use corresponding fixtures and related programs for welding processing according to the characteristics of the vehicle model. It integrates technologies such as rapid positioning of the white body, laser brazing, welding, and the application of industrial robots for handling, achieving a welding speed that improves the previous generation product system by 32%, reduces process costs by 43%, increases body stiffness by 29%, meets the needs of online production, and greatly improves the speed and seam quality of automotive welding, enabling the automation and intelligence of the body welding production line.

2. Laser welding equipment for automotive airbag liners
The airbag explosion is controlled by a gas generator, and during the explosion, an oxidation reaction occurs, generating a large amount of gas and causing an explosion. Therefore, the sealing requirement for the airbag liner is very high, and during the processing of the liner, overheating must be avoided. Laser welding is a very suitable processing method.
Its technical characteristics include a large weld penetration, reaching 2-3mm, high welding strength, small heat-affected zone, and minimal welding deformation; high degree of automation, easy control, and fast speed; high welding accuracy, stable repeatability, and high yield; non-contact processing, no need for welding auxiliary tools; welding does not require welding rods or filler materials, achieving welds without impurities and pollution.
3. Laser weakening equipment for automotive airbag panels
Advanced laser weakening equipment for automotive airbag panels integrates automatic loading and unloading laser processing, combining robotic technology with laser weakening processes. It has excellent indicators and performance, accurately controlling the remaining thickness, and the time required to produce a safety airbag panel is less than one minute, replacing traditional methods such as injection molding weakening and cold knife weakening. Its features include a pre-positioning device to ensure processing accuracy; precise weakening processes to guarantee the accuracy, stability, and repeatability of the weakening depth; and traceability of production data.
4. Laser welding equipment for automotive exhaust pipes
Laser welding is a process that uses a focused high-energy laser beam to melt and connect materials, forming excellent weld joints. Laser welding has characteristics such as fast welding speed, minimal workpiece deformation, large weld fusion ratio, fine grains, simple post-welding treatment, and good weld quality, enabling welding of the same or different materials or difficult-to-weld materials in various special environments.
5. Laser welding equipment for automotive bumpers
Automotive bumpers are irregularly shaped parts, and using traditional stamping methods is very complex, and the parts are prone to deformation and stress. Using laser methods does not require complex fixture systems, has no processing stress, and the cut edges are not deformed, making it more suitable for later processing and installation. Its features include advanced laser welding technology that can improve welding quality, high strength of the weld joints that can reach the same strength as the base material; stable performance of laser welding equipment, good repeatability, and high reliability, with aesthetically pleasing weld joints; due to the flatness of laser welding, the welded workpieces will not damage other components during production.
6. Laser welding equipment for automotive trunks
The trunk consists of the trunk lid and the rear panel. Due to the 90-degree angle in its formation, laser brazing is used for welding. Traditional trunk welding uses MIG brazing, and since the trunk material is usually galvanized sheet, the low heat input of MIG brazing is used to solve the problem of significant burning of the galvanized layer. However, the high-speed welding of MIG and the instability of the arc at low current limit its efficiency and quality. Laser welding mainly targets welding with complex shapes or where the direction of the weld seam changes sharply, resulting in a smooth surface. Additionally, MIG brazing is difficult to form smooth welds and has significant pollution. Using laser brazing results in high welding speed, good weld formation, stable quality, minimal burning of the galvanized layer, and minimal deformation.
7. Laser welding equipment for automotive gears
Laser welding of automotive gears is a developing trend. Currently, major automotive manufacturers worldwide are competing to adopt laser welding for gears, replacing resistance welding, induction welding, electron beam welding, and other processes to enhance product competitiveness in the international market. Laser welding of gears does not require a vacuum, avoiding welding deformation, and the welded gears do not require further precision machining. Gear welding can reduce the number of parts, improve gear quality, and lower manufacturing costs. Currently, advanced welding in the market can achieve a weld depth-to-width ratio of 10:1 or even better, and the mechanical properties at the weld seam are not inferior to the base material, ensuring that the strength of the product is not weakened, realizing the functional characteristics of high torque in gears.
8. Fully automatic laser cutting equipment for automotive shift sleeves
Fully automatic laser cutting equipment for automotive shift sleeves can replace traditional processing methods. Its technical characteristics include fixed optical path design; a two-station disc feeding system; four-point flexible pre-positioning for accurate and reliable part clamping; high cutting surface quality; high processing accuracy; fast processing speed and high efficiency.
The variety of automotive component types, specifications, and quantities indicates a significant potential for the application of laser welding in their production. Moreover, many large components do not necessarily have to choose laser processing equipment for welding and cutting. At the same time, the power batteries used in new energy vehicles cannot do without laser welding processing, which not only improves the quality and safety of power batteries but also plays a good role in promoting the production efficiency of enterprises!
