A device for the electron-beam welding of two components to form a component of nickel-based alloys, which has at least a vacuum chamber, in which an electron radiation or laser radiation is generated and is directed onto a joining zone of two components to be joined.

Abstract: This disclosure relates to a method for connecting a strand element to a connection element using a re-shaping method, such as a connecting a cable lug. A system is also disclosed which comprises a pair of receiving elements having a front side with a recess and a hollow section. The hollow section is designed to accommodate a press insert having a front side with a recess. The receiving element and the press inserts are arranged in a vice. The system also comprises a clamp having a front side with a recess, which is suitable for receiving the connection element. When a pair of receiving elements is arranged, together with the press insert, around a central region of the connection element, then a re-shaping connection, such as a crimp connection, is produced between the strand element and the connection element.

Abstract: The invention proposes a method for cohesive joining to a cable end (1), in which method a welding tool element (30, 37, 41, 43, 45, 48, 53) is fitted on an open bundle end of individual cores (2, 15) of the cable end (1), welding energy is fed into the individual cores (2, 15), and the welding tool element (30, 37, 41, 43, 45, 48, 53) is removed from the bundle end. In the process, an engagement recess (7, 21) can be formed in the open bundle end, an engagement pin (6, 20, 31, 38, 42, 44, 46, 49, 54) of the welding tool element (30, 37, 41, 43, 45, 48, 53) can engage into the engagement recess (7, 21), and at least a portion of the welding energy can be fed via the engagement recess (7, 21).

Abstract: The invention relates to a method for producing a component (1, 2) consisting of a fibre-reinforced plastic and prepared for the welding of a metal component (4), which comprises at least one fibre element (2) impregnated with a plastic matrix, wherein at least some portions of at least one metal joining partner (1) are integrated into a fibre element, a first section of the joining partner (1) being surrounded by the fibres of the fibre element (2) such that it is in contact therewith, and a second section of the joining partner (1) projecting over a surface of the fibre element (2) or lying at least in the surface, the joining partner (1) being connected, by at least some portions, to the liquid and hardening plastic matrix, especially at least by the first section. The invention also relates to a metal joining partner for integrating into a component consisting of fibre-reinforced plastic in order to weld a metal component (4) thereto.

Abstract: A method for producing a bonded joint between a light metal of a first component and a steel material of a second component, wherein a protective-gas joining process is used, a zinc-based filler material is used, and wherein an arc of the protective-gas joining process reaches at least the steel material of the second component, wherein a phase space of at least intermetallic phase composed of iron and the light metal is produced in a joining region adjacent to the steel material. Introduction of heat occurs so that the joint to the steel material is a solder or brazed connection and, during joining, a detachment of part of the solidified intermetallic phase(s) from the steel material of the second component starts in a melt of a solder or brazed matrix formed by the filler material and the at least one intermetallic phase is embedded in the solder matrix.

Abstract: The application relates to a method for determining beam parameters of a charge carrier beam, a measuring device, and a charge carrier beam device. The charge carrier beam (4) from a charge carrier beam device (1) is guided, by means of a beam deflection unit (3), over a slit aperture arrangement which is provided in an aperture device (7) and which has one or more slit apertures (8). Measurement plane coordinates of the beam components that penetrate the slit aperture arrangement are determined. On the basis of the measurement plane coordinates, the aperture device automatically moves in such a way that a measuring aperture (9) arranged in the aperture device moves over a predefined measurement reference point. The beam parameter is measured by the measuring aperture. In a measuring device (5) suitable for carrying out said method, the slit aperture arrangement has at least two non-parallel slit aperture sections (12, 13, 15, 16) which can be part of a single continuous slit aperture.

Abstract: A cassette for a high-temperature fuel cell stack, comprising at least one fuel cell including an anode, a cathode, and an electrolyte, and a metal cell frame which surrounds the fuel cell peripherally, wherein the metal cell frame has two sections, these being an inner thin compensating frame that contacts the fuel cell and a thicker, rigid outer frame which is provided for contacting the interconnector. The inner compensating frame comprises a peripheral bead at room temperature, which entirely disappears at temperatures between 980° C. and 1100° C., as a result of the prevailing stresses. The bead has special relief functions. It is significant that this special function of the formed bead is exclusively achieved by way of the warping in the compensating metal sheet or the compensating film, and is formed solely by way of the joining sequence applied, which is to say only in combination with the joining process employed.
