Abstract

Electronic welding To produce a weld, thin foil is placed over and parallel to the plates edges. A small vessel contg. at least one electron gun is then placed over the foil and is sealed to it by a peripheral joint. Vacuum is created in the vessel chamber and between the foil and plates, and the electron beam pierces and melts the foil to the plate joint. The vessel is then moved longitudinally to produce a continuous weld. Supplementary strip may be added when the gap between the plates is large. Conventional methods require the whole weld equipment to be set-up inside a large vacuum chamber.
