摘要： There is provided electron beam welding apparatus comprising an electron beam gun (50) associated with a welding chamber (54) configured for welding of a battery array (33) to a bus bar (32) and beam adjustment devices (56, 58) operative in response to a controller (60) to modify beam characteristics and position of an electron beam (52) generated by the electron beam gun (50), wherein at least two subsidiary chambers (70, 72) are disposed on opposing sides of the welding chamber (54), all chambers being evacuable to be under a vacuum, and a beam detector (61) is positioned proximal the welding chamber (54) to generate data relating to beam characteristics and position, the controller (60) configured to respond to data from the beam detector (61) to control synchronously the beam adjustment devices (56, 58) and to create a consistent welding penetration depth for welds formed between a bus bar (32) and a battery array (33) regardless of angle of incidence of an electron beam. An associated welding method is also provided.

摘要： A welding head for a welding apparatus, the head comprising an outer face attachable to a welding device such as an electron beam gun or laser, an inner face sealable to a workpiece, and an outer sealing ring and an inner sealing ring situated within the inner face and disposed on either side of an evacuatable region, wherein the inner face has a teardrop-shaped profile. Outer and inner sealing rings can be inflatable or formed from different materials, the outer sealing ring being formed from a material with a Shore hardness of between 50 to 70 and the inner sealing ring being formed from a material with a Shore hardness of 20 to 40. A bridging seal can extend from within the inner sealing ring to the outer sealing ring.

摘要： There is provided an electron beam emitting assembly (12) comprising a filament element (40; 60) and a cathode element (42; 62), wherein the filament element (40; 60) is in direct physical contact with the cathode element (42; 62). The filament element (40; 60) is heatable to a temperature around the electron emission temperature of the cathode element (42; 62). The filament element is resistively heatable or inductively heatable. Also provided is a method of generating an electron beam comprising positioning a filament element and a cathode element in direct physical contact, and heating the filament element to a temperature around the electron emission temperature of the cathode element so as to cause the cathode element to emit electrons.
