FIELD: process engineering.
SUBSTANCE: invention relates to electron-beam welding. Proposed method comprises applying of local magnetic field to parts butt, directing of electron beam to said butt to form penetration channel and electron-beam welding of parts at bottom position with part-through penetration. Applied is magnetic field its direction being perpendicular to butt plane. Electron beam is directed at acute angle to the interface selected to make electron beam enter the penetration channel at 90°±15°, to form beam curvilinear path and to direct electron beam nearby penetration channel bottom at 0÷30°.
EFFECT: higher quality of weld joint.
