Abstract

PURPOSE: To improve the bead appearance and weld quality of the work that requires quick beam emission and stopping by causing AC deflection of an electron beam slightly before ceasing the irradiation of the beam when the irradiation is going to be ceased.
CONSTITUTION: It is assumed that with the plane of the figure as the work the intermittent weld zones (beads) 1W3 are going to be obtained by irradiating an electron beam to the work and emitting and stopping the beam quickly. In this case, the beam is vibrated like deflection waveforms 4W6. However, it is better to make the frequency of said vibrations much larger than the one shown in the figure. Then, the beam current is quickly reduced to 0, and the size of the craters produced decreases considerably. The direction for deflection can be made perpendicular to or the same as the direction of the bead 1 or the like and at their intermediate.
