The welding depth of laser welding machine has a great relationship with the performance and structure of welding materials and the power of laser welding machine equipment, so for articles with different materials and materials, it is necessary to use welding machines with different powers, and the completion effect is also different. The power of laser welding machine is generally 300 to 500 watts, but there are also higher power laser welding machines.
The surfacing thickness of 300-500 watt laser welding machine shall not exceed 65438 0.5 mm ... Of course, sometimes slightly thicker materials can be welded through strength and thermal deformation; It is required that the laser welding thickness of household appliances and high-speed stainless steel should be less than 1mm and the penetration depth should be less than1mm.
Principle of laser welding machine
1. laser emission: the laser welder generates a laser beam through a laser. The working substance in the laser (such as Nd:YAG crystal) can emit a laser beam after being excited by energy.
2. Optical system: The laser welder adjusts and controls the laser beam through the optical system. The optical system includes collimator, reflector, lens and other components, which can adjust the parameters such as the direction, focusing degree and shape of the laser beam.
3. Welding process: The laser welding machine focuses the laser beam on the welding part, so that the welding part is irradiated by the high-energy laser beam, thus generating high-temperature and high-pressure conditions, and melting and fusing the welding materials together.
4. Control system: The laser welding machine also needs to be equipped with a control system to control welding parameters such as temperature, depth and speed by adjusting laser power, wavelength and pulse, so as to obtain the required welding effect.
