Laser welding technology is mainly used to weld aircraft main structural materials such as titanium alloy and aircraft alloy siding, cylinder pads, motor boxes, cannonballs, torpedoes, aluminum alloy missile storage, etc .; laser cutting and drilling technology can be used for aircraft skin, Honeycomb structure, frame, tail siding, helicopter main rotor, engine case and rocket launcher, etc .; laser surface treatment technologies include laser quenching and laser cladding. Laser quenching uses a high-energy laser to quickly scan the surface of the workpiece, and nail covers on the surface of the workpiece Rapid absorption of energy in a small area of thickness rises to a high temperature of 600-1000 ° C in less than one second, and low-temperature quenching is completed in 2-3 seconds. The surface of the workpiece after laser quenching will be harder. Laser cladding can repair old aircraft equipment, such as aircraft engine forged blades, turbine guide blades, etc. The old equipment after cladding is as new as ever, and the performance of the equipment substrate is even better than before. Soft materials will be softer, and hard materials will be more Hard; small and medium power laser micromachining mainly includes permanent identification of instruments on aircraft, permanent identification of bearings, etc.
