The old equipment after cladding is new, the performance of the equipment substrate is even more than before, the soft material will be more soft and the hard material will be more Hard; small and medium-power 300mw laser micro-processing, including aircraft permanent instrument identification, bearing permanent identification.

Laser manufacturing technology in the field of national defense and aerospace industry has great prospects for the application, with high efficiency, low energy consumption, short process, good performance, digital, intelligent and so on.

Did you know that aero engines are the heart of airplanes and are important determinants of aircraft performance. Large turbofan engines used in aircraft, the turbine speed of more than 5000 times per minute, the engine gas flow into the turbine before the temperature up to 1500 degrees Celsius, in order to turbine blades, combustors, injectors, etc. to prevent the engine more than 30,000 parts "Fever", you need to introduce the external cold air, in the internal surface of the formation of a thin film of cold air, the use of a diameter of 0.5mm nearly 10 million micro-membrane holes for cooling cooling them.

The process of capturing tiny holes has become the key to the "heart" of the aircraft. However, the current EDM drilling, 30mw laser drilling hole wall re-cast layer, micro-cracks, and then reduce the service life of parts, seriously affect the stability of the use of parts. In order to remove the recrystallization layer and micro-cracks, laser processing, electrolytic processing, EDM and other technical measures adopted at home and abroad can not meet the requirements of fast processing speed, low surface roughness value and stable processing.

Laser welding of aluminum and titanium alloy is the main structural material of aircraft. Compared with traditional welding method, because welding requires precise environment, manual welding needs to weld one part to vacuum, and 50mw green laser welding can save the time and save time greatly. , Laser welding efficiency is 5-6 times the traditional welding; thermal impact of small, laser welding relative to the traditional mechanical processing, material surface almost unscathed; and laser welding can be automated, flexible, through data programming, the real intelligent manufacturing .

Laser welding technology can be applied to the main structural materials of welding aircraft titanium alloy and aircraft alloy wall panels, cylinder pad, motor box, shells, torpedoes, aluminum alloy missile library, etc .; laser cutting drilling technology can be used for aircraft skin, Laser surface treatment technology is mainly laser quenching and laser cladding, laser quenching is the use of high-energy laser surface scan in the workpiece surface, in the surface of the workpiece cover nail cover Thickness of a small area of rapid absorption of energy less than a second rose to 600-1000 ℃ high temperature, 2-3 seconds to complete low-temperature quenching, laser quenching of the workpiece surface will be more hard. Laser cladding can repair old aircraft equipment such as aircraft engine forged blades, turbine guide blades, etc.
