摘要： A method of and apparatus for regulating an electron-beam welding generator of the kind having three electrodes viz: a cathode, a Wehnelt electrode and an anode. The method is characterized by a suitable combination of two methods of regulating an electron beam welding gun. One of these methods includes varying and regulating the very high voltage while maintaining the voltage applied to the Wehnelt electrode at the potential of the cathode (operation of the "diode" kind). The other method includes holding the very high voltage constant while regulating or programming the welding current by means of the voltage to the Wehnelt electrode (operation of the "triode" kind). The variations in and regulation of the very high voltage are controlled by an induction regulator associated with a thyristorized regulator.

摘要： In the positioning of an assembly of work tools which are required to operate in the plane of the end face of a tubular structure, which is not necessarily orthogonal to the axis of the structure, a theoretical end face is determined by three sensing arms spaced apart by 120.degree., which, by an axial translatory movement followed by two pivotal movements about axes parallel to lines joining pairs of the arms, is brought into coincidence with the actual end face of the structure, then the plane of operation of the tools is brought into coincidence with the plane of coincidence of the theoretical and actual end faces.The work tools may for example be electron beam welding guns for welding an additional tubular element to an existing tubular structure.
