Abstract
A machine for the internal butt welding of two tubes comprises a fixed axial electron gun, a rotary prism system for radially deflecting the electron beam and comprising a plurality of prisms and a deflection system for cyclically delivering the electron beam emitted by the electron gun successively to each of the prisms at a high frequency, the relative duration of utilization of each prism being modifiable in the course of the rotation of the rotary system.
