1. Laser heat treatment technology: Laser heat treatment is a high-tech process for rapid local surface quenching, which is primarily used to strengthen the surface of components. It can increase the surface hardness, wear resistance, strength, and heat resistance of metal materials and parts, while allowing the core of the parts to retain good toughness. As a result, the mechanical properties of these parts feature excellent wear resistance, high impact toughness, and high fatigue resistance. The use of laser heat treatment technology can significantly improve product quality and double the service life of products. Laser heat treatment has significant advantages over traditional quenching processes: the surface hardened layer has a fine and uniform structure, is not restricted by the shape of the part, can achieve a hardness of up to HRC60, and its thickness can reach up to 4 MM. 2. Laser cladding technology: A laser-based process that deposits a layer of material with specific physical properties on the surface of a designated workpiece, in order to improve its surface properties or restore the original geometric dimensions of the part. High-performance materials can be optionally used to modify the substrate surface, resulting in a cladding structure that is fine-grained, free of micro-defects, and features high metallurgical bonding strength. Laser cladding technology can also be used to repair holes and cracks on the surface of materials, restoring the geometric dimensions, morphology, and properties of damaged workpieces. 3. The application of laser processing technology imposes no restrictions on the geometric dimensions of mechanical parts’ shapes; laser processing can be carried out wherever the laser can reach ； There are no restrictions on the base material; steel, iron, non-ferrous metals, and certain types of cemented carbides can all be repaired ； The metal surface can be modified to enhance the physical properties of parts such as wear resistance, corrosion resistance, and heat resistance, thereby extending their service life and reducing production costs.
