ELECTRON BEAM WELDING METHOD Russian patent published in 1997 - IPC

Abstract RU 2071401 C1

FIELD: welding; process control devices. SUBSTANCE: method includes changing of electron beam focusing depending on deflection of electron beam from axis of welding pool. Focusing current modulation frequency is two times as high as main harmonics of signal setting deflection of beam across butt weld. EFFECT: enlarged operating capabilities owing to provision of operative dynamic changing of electron beam focusing. 2 dwg
