Title: Welding pool support device for energy beam welding

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.
