METHOD OF ELECTRON BEAM WELDING OF NONMAGNETIC METALS AND ALLOYS Russian patent published in 2011 - IPC B23K15/00 B23K28/02 

FIELD: process engineering.

SUBSTANCE: invention relates to method of electron beam welding of nonmagnetic metals and alloys. Proposed method comprises penetrating the butt of parts 3 to be welded together by electron beam 2, inducing magnetic field inside said parts and forming presser geometry of electron beam and penetration channel in displacing electron beam over part thickness. Blind penetration of but 4 is performed. In welding, beam 2 is deflected across the butt to vary shape and sizes of seam root 6 at constant size of weld seam apex. For this, variable magnetic field is induced on the side of seam root.

EFFECT: higher quality of welded joints, control over weld seam shape.
