China's large metal parts laser additive manufacturing technology made new breakthroughs

The manufacture of large-scale key components such as titanium alloy, high-strength steel, heat-resistant alloy and other high-performance refractory metals is the foundation of major equipment manufacturing industries such as aviation, aerospace, electric power, petrochemical and shipbuilding. High-performance large-scale metal components additive manufacturing technology is expected to provide a transformative fast, flexible, low-cost, high-performance and short-cycle new technology for the manufacture of large metal components that are difficult to be processed in major national defense and industrial equipment. In the future Applications in the manufacture of high-end and major equipment such as aviation, aerospace, nuclear power, petrochemicals and ships are promising and have drawn great attention from governments, industry and academia around the world.

Beijing University of Aeronautics and Astronautics and other equipment design, manufacturing enterprises through "production and research" work closely to target the country's major needs, after 20 years of continuous research and development, with the support of the Beijing Municipal Science and Technology Commission, the first breakthrough in the international titanium alloy, super High-strength steel and other large overall bearing force of the key components of laser additive manufacturing process, quality performance control and application of key technologies, the establishment of a set of technical standards system, developed with a series of original core technology, so far the world's ability to shape the largest laser additive The manufacturing of complete sets of equipment has been applied to the development and production of key equipment such as large aircraft, new fighters, new missiles and satellites in our country and played an important role in ensuring the smooth development of the equipment.
