    Abstract: A method and an apparatus for the control of the filler material supply rate in energy beam welding as electron beam welding is disclosed. The width or cross-sectional area of a gap defined by opposed faces of two workpiece parts to be joined is measured by radiation, preferably X-ray radiation, and the rate with which filler material is supplied into a welding zone produced by the energy beam is controlled in proportion to the result of the measurement. The measurement may be made in advance of the welding zone and the control is then delayed by a period of time, which the welding zone takes to arrive at the position of the gap, where the measurement was made.

    Abstract: In an electron beam machine for e.g. beam welding, the beam current I.sub.em is stabilized by negative feedback applied to the grid of the electron gun. The optimum cathode heating current is ascertained by causing the cathode heating current I.sub.H to decrease steadily from a maximum value. The beam current is kept constant by the feedback, which adjusts the grid voltage U.sub.W to offset the decrease in cathode temperature caused by the decreasing heating current; the rate of change of the grid voltage U.sub.W is monitored, and when this rate of change exceeds a threshold, the decrease in heating current is arrested, and the heating current is maintained at the thus established optimal value or preferably set at a slightly higher value, which secures an extended length of life of the cathode. This setting of the cathode heating current is repeated after a predetermined interval of time to establish a new value in response to a change of the condition of the cathode.

    Abstract: A method and apparatus for seam welding by means of a charged particle beam is disclosed, wherein any misalignment of the beam with respect to the gap between opposed surfaces of two workpiece parts to be joined is compensated for by a double deflection of the beam. The position of the beam in respect to the gap is determined at two locations spaced in the direction of propagation of the beam, and the deflection in two spaced deflection zones is controlled in response to the result of such determination so that the deflected beam--which may oscillate transversely to the longitudinal direction of the gap--is aligned to the gap and a sound weld seam is produced.

    Abstract: In an energy beam welding method, as an electron beam welding method, wherein an elongated body or wire of filler material is introduced in a welding zone produced by the beam and comprising fused material, the filler material body is used to act on the fused material to prevent it from flowing out of the welding zone, which would cause voids and other defects of the seam produced. The method is particularly useful in welding thick workpieces as sheet metal plates with thicknesses of one to two inches and more.

    Abstract: An account is given of a welding pool support device for energy beam welding, with a metal structure, which on a beam outlet side of a welding seam zone of a workpiece system is put against the beam outlet side and being in contact with it by a number of touching points for stopping any movement of melt out of the welding zone, which is achieved by the energy beam in the workpiece system, by a relative movement of the energy beam and the workpiece system, the former going along the weld seam zone. A supporting structure, which is able to be so changed in shape that it takes into account uneven parts of the beam outlet side of the workpiece system in the long direction and also in the cross-direction of the weld seam zone. Furthermore the supporting structure is so designed at the side touching the beam outlet side that the distances between the points of touching from each other and from the parts placed between them, of the supporting structure, that gases, produced in the welding zone near the beam outlet side, are able to come out through the supporting device.
