The working principle of laser cutting

2025-05-21

The basic principle of laser cutting is to generate a high-energy laser beam (such as CO ₂ laser, fiber laser, or YAG laser) through a laser generator. After the laser beam is focused by an optical system, it forms an extremely small spot (diameter can be less than 0.1mm) with a power density of up to 10 ⁶~10 ¹ ² W/cm ². After absorbing laser energy on the surface of the material, the instantaneous temperature rises to the melting point, boiling point, or ignition point, forming a molten or vaporized state. At the same time, auxiliary gases (such as oxygen, nitrogen, or compressed air) are emitted coaxially with the laser through a nozzle to blow away slag and participate in combustion reactions (such as oxygen assisted carbon steel), thereby improving cutting speed and quality. By controlling the movement of the laser head or workpiece through the numerical control system, precise cutting is completed according to the preset path. ...

The technical characteristics of laser cutting are mainly reflected in the following aspects: High cutting accuracy: Laser cutting can achieve high-precision cutting, with a cutting accuracy of about ± 0.05mm to ± 0.1mm. The laser beam is focused into an extremely small light spot, achieving a high power density at the focal point. The material is rapidly heated to the point of vaporization, forming a very narrow slit. The two sides of the slit are nearly parallel and perpendicular to the bottom surface. Good cutting quality: The cutting edge of laser cutting is vertical, the cutting edge is smooth, and the surface roughness is only a few tens of microns, which can be directly welded or other subsequent processes without correction. After laser cutting, the width of the heat affected zone of the material is very small, and the deformation of the workpiece is small, ensuring the dimensional accuracy and appearance quality of the cut parts. Fast cutting speed: Laser cutting has a much higher cutting speed than traditional cutting methods, such as cutting 1mm thick aluminum alloy plates at a speed of up to 40m/min. The laser cutting machine uses computer-controlled laser beams to cut materials in one go, greatly improving production efficiency. Wide material adaptability: Laser...

Laser welding principle of welding robot

2025-05-21

Welding robot laser is a monochromatic, directional focused energy beam produced by using stimulated radiation to amplify light, which can obtain a diameter of less than 0.01mm and a power density of up to 10W/㎡. It can be used as a heat source for welding, cutting, and material surface cladding. When laser light waves are incident on materials, the charged particles in the material vibrate according to the rhythm of the light wave electric vector, converting the radiation energy of photons into the kinetic energy of electrons. After absorbing laser, substances first generate excess energy of certain particles, such as the kinetic energy of free electrons, the excitation energy of bound electrons, or excess phonons. These original excitation energies are converted into thermal energy through a certain process. Besides being electromagnetic waves like other light sources, lasers also have characteristics that other light sources do not possess, such as high directionality, high brightness (photon intensity), high monochromaticity, and high coherence. During laser welding processing, the conversion of light energy absorbed by the material into thermal energy is completed in a very short time (about 10 seconds). During this time, thermal energy is limited to the laser radiation area of the material,...

What are the advantages of using laser welding robots

2025-05-21

1. In line with the trend of environmental protection development. In traditional welding, smoke, dust, harmful gases, etc. are prone to occur, which have a certain impact on the environment. Laser welding robots use electron laser beams for welding, which focus into electron laser beams through high voltage. During the welding operation, the kinetic energy of electrons is converted into heat energy, causing local melting of the workpiece material to achieve welding. Electron laser beam welding does not require the use of welding materials, has minimal environmental hazards, and is not easily oxidized. 2. Real time monitoring of the production process to ensure welding quality. Laser welding robots are equipped with multiple sensors that can monitor the welding process in real-time. In the event of a malfunction, an alarm signal will be issued, and the output power and size of the laser focusing point will be dynamically adjusted according to production and processing regulations. Suitable welding parameters will be used for different welding parts to control the welding quality. 3. Flexible running speed and wide application range. The laser welding robot adopts a multi axis design. In order to improve welding flexibility, it can also be equipped with a welding positioner to enhance its flex...
