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 work piece manipulators under computer and CNC control for the quality and precision demanded within the aerospace industry sectors.
Why use an Electron Beam?
In general the world aircraft industry requires "100% critical, defect free welds". The electron beam welding process is ideally suited to this need. The high power density beam of electrons produces narrow welds of high integrity and with minimum distortion. Welds can be produced in a wide range of materials including titanium alloys, aluminum 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 that the stringent inherent safety requirements can be met.
Front bearing housing
This extremely complex assembly is fabricated from a number of relatively simple components. Few other welding process could be successfully employed for this type of product. Linear, circumferential and planetary welds are employed during succ
Welds of high integrity are demanded in this major rotating component in 901 nickel. Fabrication by electron beam welding achieves savings in weight, material and machining costs.
Stator Blade Assemblies
Fabricated using electron beam welding to join the many blade sections together results in a precise, repeatable weld. Titanium is perfectly suited to EB welding.
