Innovative application and development of laser technology in the field of material processing - focused on cutting / welding / additive manufacturing / surface modification technology

Ⅰ. Technical core and advantages
With the characteristics of strong directionality, high energy density (up to 105 1015W/cm2), and good spatio-temporal control, laser technology has become the core processing method in aerospace, automobile manufacturing and other fields. Commonly used industrial lasers include CO2 lasers, fiber lasers, etc., with a maximum output power of 100kW for high-power fiber lasers. Its core advantages are reflected in the strong process integration, which can complete multiple processes with one equipment; The material has a wide range of applications, and can process a variety of materials such as metals and non-metals. High processing accuracy and efficiency, small heat-affected zone, small workpiece deformation, in line with the needs of green and sustainable development.
Ⅱ. Four core application areas
Laser cutting: melting vaporized materials through high-energy laser beams, auxiliary gas blowing off slag, suitable for metal sheets, sapphire and other materials, ultrafast laser can achieve micron-level accuracy, raw material saving 15%-30%, widely used in automobile body and aircraft skin processing.
Laser welding: divided into deep melt welding and conduction welding, with large penetration depth and narrow heat-affected zone, widely used in ship repair and automobile manufacturing, composite welding process optimizes weld quality, handheld equipment expands thin plate welding scenarios, and 25% of the welding tasks in the manufacturing industry are completed by it.
Laser additive manufacturing: Including SLM and LMDF technology, it can realize the "free manufacturing" of complex structures, successfully manufacture titanium alloys, superalloys and other components, and apply them to engine parts and biological implants, with significant weight reduction effects.
Laser surface modification: including hardening, deposition and other processes, which can improve the hardness and wear resistance of materials, and ultrashort pulse lasers can prepare superhydrophobic and drag reduction functional surfaces, which can be used in auto parts and aero engine blades.
