Core Working Principle
Laser welding uses a laser to generate laser light of a specific wavelength, which is focused by an optical system into an extremely fine, high-energy-density beam. When the laser beam strikes the workpiece surface, the material rapidly absorbs the light energy and converts it into heat, instantly melting or even vaporizing the welded area. Upon cooling, the molten metal forms a solid weld pool, creating a permanent bond.
Compared with traditional arc welding, argon arc welding, and other methods, laser welding offers unparalleled advantages:
High Precision and Minimum Heat-Affected Zone:
The laser beam can be focused to an extremely small spot (down to the micron level), enabling precise welding even down to the micron level.
Highly concentrated energy, low heat input, and minimal thermal deformation prevent damage to the workpiece due to overheating.
Excellent Weld Quality:
The weld is beautiful, smooth, and free of pores, requiring minimal or no post-processing.
The weld strength is high, often matching or exceeding the strength of the parent material.
High Efficiency and Speed:
The welding speed is high, far exceeding that of traditional welding methods, significantly improving production efficiency.
It is easily integrated with automation systems (robots, CNC workstations), enabling mass automated production.
Strong Material Compatibility:
It can weld high-melting-point, high-hardness, and brittle materials (such as titanium alloys, aluminum alloys, copper, and ceramics).
It can effectively weld dissimilar metals.
Non-contact processing and high flexibility:
No mechanical stress, no tool wear, and remote transmission via optical fiber facilitates complex routing and long-distance processing.
Various welding methods (pulse welding, continuous welding) are available, including spot welding, stitch welding, and seal welding.
Clean, environmentally friendly, and automated integration:
The welding process is dust-free, quiet, and environmentally friendly.
Easy integration into smart production lines aligns with Industry 4.0 trends.
Advantages:
1. The laser welding machine adopts 1500 watt fiber laser, which has high photoelectric conversion efficiency and long life of 100, 000 hours. The energy provided by electric energy is 25%-30% converted into laser energy, and the photoelectric conversion rate is many times than that of YAG laser.
2. The energy density is high, the heat input is low, the amount of thermal deformation is small, and the melting zone and the heat-affected zone are narrow and deep.
3. High cooling rate, which can weld fine weld structure and good joint performance.
4. Compared with contact welding, laser welding eliminates the need for electrodes, reducing daily maintenance costs and greatly increasing work efficiency.
5. The weld seam is thin, the penetration depth is large, the taper is small, the precision is high, the appearance is smooth, flat and beautiful.
6. No consumables, small size, flexible processing, low operating and maintenance costs.
7. The laser is transmitted through fiber optics and can be used in conjunction with a pipeline or robot.
Product advantages:
The laser welding machine adopts 150-3000 watt fiber laser source, which has high photoelectric conversion efficiency and long life of 100,000 hours. The energy provided by electric energy is 25%-30% converted into laser energy, and the photoelectric conversion rate is many times that of YAG laser.
Application:
It is widely used in the automotive, machinery manufacturing, medical equipment, shipbuilding, chemical industry, aerospace, aviation, power battery and daily necessities industries.
