BEIJING ZHONG KE ELECTRIC CORP.
Electron Beam Welding
 
Mostly of EB welding equipments are directly used on the spot production line, typical applications are as following:
l        EB welding the torque converters of BUICK car for Shanghai Volkswagen Automotive Co. Ltd.(CSVW)
l        EB molding welding the crossbeam in the cab of POLO car and TOURAN business trip car for Shanghai General Motors(SGM)
l        EB seal welding the Ti-tube of the radiation isotope for controlling cancer against its diffusion
l        EB local vacuum welding the shuck body used for adjusting the fly gesture of the satellite.
l        EB welding the wheel frames of the planet gears and difference speed gears
l        EB welding the Auto transmission gears
l        EB penetrate welding the absorber with the silicon oil
l        EB seal welding the Al-piston of auto air-condition
l        Double gun sliding seal vacuum EB continual welding production line for bi-metal
 
Characteristics of EB Welding Technology
 
Electron beam welding technology offers important advantages to the production engineer for many process application, mainly including.
◆    low distortion components
◆    high deeply penetrating weld(up to 50 : 1 depth/width ratio)
◆    no oxidation
◆    accuracy and repeatability
◆    joining of difficult to weld and dissimilar metals and alloys
◆    consistent high quality welds
◆    no filler material and vee grooves
◆    great depth of seem in one pass (ranging from 0.5mm to 500mm)
