How laser processing technology works

Laser processing technology is a processing technology that uses the characteristics of the interaction between the laser beam and the substance to cut, weld, surface treat, punch and micro-process materials (including metals and non-metals). As an advanced manufacturing technology, laser processing has been widely used in important sectors of the national economy such as automobiles, electronics, electrical appliances, aviation, metallurgy, machinery manufacturing, etc., and plays an increasingly important role in improving product quality, labor productivity, automation, pollution-free, and reducing material consumption.

Laser processing uses a high-power-density laser beam to irradiate the workpiece, melt and vaporize the material, and perform special processing such as piercing, cutting, and welding. Early laser processing was mostly used for making small holes and micro welding due to its low power. By the 70s of the 20th century, with the emergence of high-power carbon dioxide lasers, yttrium aluminum garnet lasers with high repetition rate, and in-depth research on laser processing mechanisms and processes, laser processing technology has made great progress, and the scope of use has expanded.

Laser processing machines of several kilowatts have been used for high-speed cutting, deep penetration welding, and heat treatment of various materials. A variety of special laser processing equipment has emerged, and combined with photoelectric tracking, computer numerical control, industrial robots and other technologies, greatly improving the automation level and use function of laser processing machines.

The high-intensity laser output from the laser is focused onto the workpiece through the lens, and the power density at its focal point is as high as 10( 10( Watt cm (, and the temperature is up to 10,000 degrees Celsius, and any material will be melted and vaporized instantaneously. Laser processing uses the thermal effect of this light energy to weld, punch and cut materials. The lasers commonly used for processing are mainly solid-state lasers and gas lasers.

How does laser processing work? All of a sudden, it's as beautiful as fireworks!

Laser processing is to irradiate a laser beam to the surface of the workpiece, and use the high energy of the laser to remove, melt the material and change the surface properties of the object. The principle is to use the laser beam to interact with the substance, so that the workpiece is melted at high temperature and thrown by the shock wave under the photothermal effect, so as to realize the cutting, welding, surface treatment, punching and micromachining of materials (including metals and non-metals). It has the following characteristics:

1. Because it is non-contact processing, and the energy of the high-energy laser beam and its moving speed are adjustable, it can achieve a variety of processing purposes;

2. It can process a variety of metals and non-metals, especially materials with high hardness, high brittleness and high melting point;

3. In the process of laser processing and beam elimination, there is no wear of "knife and shirt carrier", and no "cutting force" acts on the workpiece;

4. In the process of laser processing, the laser beam has high energy density, fast processing speed, small heat-affected zone, small thermal deformation of the workpiece, and small follow-up processing volume;

5. It can carry out various processing on the workpiece in the closed container through transparent medium;

6. The laser beam is easy to guide and gather to transform in all directions, and it is easy to cooperate with the numerical control system to process complex workpieces;

7. The use of laser processing, high production efficiency, reliable quality, good economic benefits.
