METHOD OF ELECTRON-BEAM WELDING OF PARTS Russian patent published in 2017 - IPC B23K15/00 B23K33/00 

FIELD: electricity.

SUBSTANCE: invention can be used for butt joints of titanium alloys with through penetration with width of up to 15 mm. The method includes cutting the welded edges of the welding parts with the execution of an additional projection with a reference point on one of the parts from its outer side, installing the parts butt-to-butt on the welded edges, aiming the electron beam on the mentioned reference point with the location of its axis in the joint plane of the parts and simultaneously melting the additional projection and the welded edges of parts with the electron beam. The welded edges are made at right angle to the outer surface of the parts. The additional projection is made with a cross-section in the form of a rectangle with the location of its center in the plane of the welded edge of the part, wherein the reference point is made in the form of a graduation mark located in the plane of the welded edge of the part and transverse slits with depth to the plane of the welded edge of the part are made on the projection.

EFFECT: reducing the labour intensity of processing parts for welding and improving the quality of welded seams.
