ABSTRACT:
For carrying out electron beam welding, there is formed by means of a magnetic or electric field set up by an even number of at least two magnetic poles or electrodes, an electron beam, the pattern of which has elliptical or similar shaped cross sections. Electron beam welding is performed using such an electron beam. The direction of the major axis of the cross section of the electron beam at the surface of the material being welded and the direction of the major axis of the cross section of the electron beam at the bottom of the beam cavity, i.e., the root portion, are at right angles to each other.
