METHOD FOR ELECTRON BEAM WELDING WITH BEAM OSCILLATION Russian patent published in 2021 - IPC B23K15/02 H01J37/302 

FIELD: welding.

SUBSTANCE: invention relates to a method for electron beam welding. The method includes moving an electron beam at a welding speed Vwel and oscillating the electron beam in the form of sawtooth oscillations along a joint of parts being welded with the formation of a welding bath and a steam-gas channel of a given depth. At the beginning of each oscillation period, the electron beam is directed orthogonally to a plane of parts being welded. During the oscillation period, the electron beam is moved in the direction opposite to a welding direction, with a constant speed V > 2 Vwel. Upon reaching a displacement value equal to an oscillation amplitude A = 0.5-2 of the diameter of the steam-gas channel, the electron beam is pulsed in the welding direction until the orthogonal orientation of the electron beam relatively to the surface of parts being welded is restored.

EFFECT: economic costs are reduced, technological capabilities are expanded, and the quality of welded joints is improved during electron beam welding of parts of large thicknesses.
