Advantages and Industry Applications of Laser Welding Machine

Laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding. With the continuous upgrading and transformation of laser welding machine technology, laser welding machine has significant advantages compared with traditional welding methods.

Laser Welding Advantages

1.Beautiful Welding Seam: Stable beam quality, small heat-affected area during welding; no deformation of the workpiece, no welding scar; firm welding; smooth and beautiful welding seam, reducing the follow-up grinding process, saving time and cost.    

2.High Production Efficiency: The laser welding machine has fast speed, relatively deep penetration, and high yield of different materials welding, which is 2-10 times faster than traditional welding. The laser welding machine is also equipped with cold water equipment to ensure continuous work for 24 hours.   

3.Safety and Environmental Protection: The laser welding machine is green, safe and environmentally friendly. Traditional argon arc welding will produce a large amount of welding dust and scum, which has a greater impact on the environment, while the handheld laser welding machine has a relatively small impact on the environment.   

4.Low Labor Cost: Taking argon arc welding as an example, argon arc welding requires mature welders, while hand-held laser welding machines only require ordinary operator.     

5.Less Consumables and Long Life: Less consumables and long life, which can meet long-term welding; hand-held laser welding machine basically does not need consumables cost.

Industry Applications of Fiber Laser Welding System

With the rapid development of laser technology, laser application technology has become more and more widely used in fields such as automobiles, aerospace, defense industry, shipbuilding, marine engineering, nuclear power equipment, high-tech electronics, precision processing, and biomedicine.

Fiber Laser Welding System in Automobile Manufacturing Industry

In the automobile manufacturing process, laser welding technology is mainly used for tailor welding of body plates with different thicknesses, body welding and welding of auto parts. The use of laser welding technology can not only reduce the weight of the car body and achieve the effect of energy saving and emission reduction, but also reduce the stamping and assembly costs in the car manufacturing process, improve the assembly accuracy of the car body, the rigidity of the car body and the degree of integration of the car body, thereby increasing the comfort and safety of the car. 

Laser Welding Machine in the Electronics Industry

Laser welding has been widely used in the electronics industry, especially in the microelectronics industry. Due to the small heating concentration and low thermal stress in the heat-affected zone of laser welding, it shows unique advantages in the packaging of integrated circuits and semiconductor device casings. In the development of vacuum devices, laser welding has also been applied, such as molybdenum focusing electrode and stainless steel support ring, fast hot cathode filament assembly and so on.

Laser Welding Machine in the Construction Machinery Industry

Some products in the construction machinery industry have adopted hand-held laser welding to replace traditional argon arc welding and other welding methods, such as tower crane cab welding. Compared with traditional welding methods, hand-held laser welding has less distortion, high efficiency, beautiful appearance, and customer satisfaction.

Steel Laser Welding Machine in the Livestock Equipment Industry

At present, the livestock equipment industry, especially the welding of feed troughs, has adopted a large number of handheld laser welding, not only the hand-held laser welding welding seam is beautiful, the worker efficiency is high, because the thermal deformation generated by it is small, it can effectively control the trough blanking and improve the product quality.
