    摘要: 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.

    摘要: Disclosed is a method for producing an elongated weld seam in a workpiece by the use of a beam of charged particles, in particular an electron beam. According to the disclosed method, a beam of charged particles is directed to impinge on a workpiece and has a selected beam current, a selected accelerating voltage and is focused by a focusing field of a selected field strength. In order to produce a weld seam there is provided a relative motion between the charged particle beam and the workpiece, to move the point of impingement along the workpiece. The relative motion has a predetermined selected instantaneous velocity. The depth of penetration of the charged particle beam into the workpiece is varied by changing a parameter selected from the group consisting of the beam current and the velocity of relative motion. According to the improvement of the invention, simultaneous with the changing of the depth of penetration, there is provided an active control to change at least one parameter selected from a second group consisting of the strength of the focusing field, the amplitude of periodic beam deflection in a direction parallel or transverse to the path of the relative motion and the frequency of periodic beam deflection in a direction parallel or transverse to the relative motion.
