DEFECT-FREE CRITICAL PARTS

lectron beam welding is ideally suited to the aerospace industry, as it typically requires 100%


critical, defect-free welds. The high- power density beam of electrons produces narrow welds of high integrity and with minimum distortion. Electron beam welding can produce welds in a wide range of materials including titanium alloys, aluminium alloys, heat-resisting and high-strength alloys, frequently used in aero-engines. These capabilities can be successfully applied to the fabrication of high critical components, ensuring they meet the stringent inherent safety requirements. We find out more from the experts at Cambridge Vacuum Engineering. The typical electron beam welding


machine for aerospace applications has a large work chamber, with a high voltage (150 kV) electron gun, of

substantial power (up to 30 kW). The work chamber is furnished with high- precision workpiece manipulators under computer and CNC control, providing the quality and precision required for the aerospace industry.


Key components The front bearing housing is an extremely complex assembly, fabricated from several relatively simple components. There are not many other welding processes that you could successfully employ for
