WELDING METHOD Russian patent published in 2007 - IPC B23K15/00 B23K28/02 

FIELD: machine engineering, namely welding processes, possibly in different branches of industry for making important designation welded joints.

SUBSTANCE: method comprises steps of melting butt of welded parts by means of electron beam; creating magnetic field for providing preset geometry of electron beam and melting-through passage; deflecting electron beam along thickness of parts and directing it towards front surface of welded parts by inlet angle is selected in range 0 -90°; passing electric current along butt and in addition deflecting electron beam from downwards to upwards in such a way that to provide outlet angle of electron beam relative to back plane of welded part equal to inlet angle of electron beam. Points of inlet and outlet of beam electrons to and from welded parts respectively are arranged in the same horizontal plane.

EFFECT: possibility for receiving high quality welded joints with small volume of metal flowing from zone of metal welding, lowered number of flaws and incomplete fusion places.
