Abstract

Abstract: Power beam (laser/electron beam) processing is an indispensable technology in the aeronautical industry, and is also the frontier of advanced manufacturing research. This paper introduces welding, additive manufacturing, surface modification using laser/electron beam. Laser/electron beam welding help achieve the integration of aircraft fuselage and aeroengine structure. Laser/electron beam additive manufacturing is used in the rapid manufacturing of complicated structure and repairing of engine blades. In the area of surface modification, laser peening greatly improves structure fatigue life; ultra-fast laser has made hole-drilling on turbine blades and nano-scale surface structure possible. Bonding strength between metal-composite is significantly enhanced when electron beam sufi-sculpt is applied on metal surface. In the final section, the future development of power beam processing technology is also discussed based on new materials, new structures, and process monitoring.

Key words: laser, electron beam, welding, additive manufacturing, surface modification
