Laser Welding
Laser welding is a processing method that uses a high-energy-density laser beam as a heat source to heat the workpiece, and uses pressure or no pressure, with or without filling material, to achieve atomic bonding of the workpiece. Laser welding includes laser self-fusion welding (including high-brightness lasers, FRM lasers, shutter multi-optical output lasers, and dual-band hybrid welding), laser filler wire welding (laser brazing), and laser arc hybrid welding.
Laser Cutting
Laser melting cutting: In laser melting cutting, the workpiece is partially melted and then the molten material is ejected with the help of nitrogen or air. Because the transfer of material only occurs in its liquid state, the process is called laser melt cutting, usually cutting stainless steel. Laser flame cutting: Laser flame cutting differs from laser melting cutting in that oxygen is used as the cutting gas. With the help of the interaction between oxygen and heated metal, a chemical reaction occurs that further heats the material. Due to this, the cutting rates achievable with this method are higher than with melt cutting for the same thickness of structural steel. Usually cutting carbon steel. Laser gasification cutting: During the laser gasification cutting process, the material vaporizes at the cutting seam. In this case, very high laser power is required.
Laser Cleaning
Laser cleaning refers to the use of high-energy laser beam to irradiate the surface of the workpiece, so that the dirt, rust or coating on the surface evaporates or peels off instantaneously, and the surface adhesion or surface coating of the cleaning object is removed at high speed and effectively, so as to achieve a clean process. It is a new technology based on the interaction effect between laser and matter, different from the traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method (wet cleaning process), it does not require any CFC organic solvents that destroy the ozone layer, no pollution, no noise, so it’s a a"green" cleaning technology that is harmless to the human body and the environment .
Laser Cladding
Laser cladding technology is a part surface modification technology. Its essence is to use preset powder method or synchronous powder feeding method to supply cladding material to the surface of the base material, and rapidly melt, expand and solidify under the action of high-energy density laser beam. Form a surface layer with extremely low dilution and metallurgical bonding with the substrate, thereby repairing defects and improving the wear resistance, corrosion resistance, heat resistance, oxidation resistance and other properties of the base layer surface.
3D Printing
Laser Additive Manufacturing (LAM) technology, also known as laser 3D printing technology, is an additive manufacturing technology that uses laser as the energy source. Laser has the characteristics of high energy density and can realize the manufacturing of difficult-to-process metals. For example, titanium alloys and high-temperature alloys are used in the aerospace field. At the same time, laser additive manufacturing technology also has the advantage of not being limited by the structure of the parts, and can be used for the processing and manufacturing of complex structures, difficult-to-process and thin-walled parts.
Precision Process
QCW laser is a powerful, reliable and practical laser that can be used in different applications to meet customer requirements. It provides researchers with a new development possibility and also brings innovation to laser technology. Useful improvements. QCW lasers have many advantages, especially high power, high efficiency, excellent beam quality, small size and low cost, and can meet the requirements of a variety of applications. On the other hand, the power consumption cost of its laser is lower than that of other lasers, especially the use cost is much lower than that of traditional YAG laser, which can meet the economic requirements.
