Abstract: A profile assembly produced from a first profile and a second profile connected longitudinally by cold joining. Both profiles bear complementary clamping structures on long sides thereof facing toward one another for cold joining together. The clamping structure of the first profile comprises a clamping head formed on a web and forming an undercut on each side of the web by way of a greater extension in the profile transverse direction in relation to that of the web. The clamping structure of the second profile comprises a clamping head receptacle for accommodating a section of the clamping head and a clinching leg, formed on a profile-exterior leg of the clamping head receptacle, having a first profile arm protruding before cold joining and a second profile arm formed at an angle thereon, the free end of which engages behind the clamping head and, before cold joining, faces toward a clamping pocket of the first profile. The clamping head receptacle is tapered with respect to its open width and/or the clamping head is tapered with respect to its material thickness of the section to be inserted into the clamping head receptacle, wherein the section of the clamping head pressed into the clamping head receptacle is connected to the clamping head receptacle in a metallically sealed manner.

Abstract: A method for producing a structural component, which has different component sections, from a high-strength alloy material. The structural component to be produced is divided into at least two component sections which differ with respect to their requirement profiles when the structural component is later used, wherein one component section must meet a higher requirement profile with respect to occurring loads, and the at least one other component section must meet a lower requirement profile. In a first production step for producing the component section with the higher requirements, a blank is brought to near-net-shape or net-shape by a massive forming process in some regions. To form the at least one component section with the lower requirement profile, a body in the form of a pre-manufactured part, which corresponds to said component section, is arranged on at least one surface region in the form of a substrate, which has not yet been brought into its near-net-shape or net-shape by the massive forming process, and is bonded to the blank in at least one following step, and/or said component section is attached to the provided surface region of the blank by a generative production method in order to also bring the aforementioned regions of the massive-formed component section to a near-net-shape. The semi-finished product produced in this manner, as a completed preform, is then brought to its net-shape in one or more steps.

Abstract: A tube for use in conjunction with a deep drilled hole comprises a light metal tube made of an aluminium alloy, having sections of different wall thicknesses arranged in the longitudinal direction of the tube and a respective coupling at each end for connecting the tube to a further tube, wherein the light metal tube is produced from an aluminum alloy containing the following elements: 2.5-5.0 wt. % Cu, 0.2-1.0 wt. % Mg, 0.8-2.0 wt. % Li, max. 0.15 wt. % Si, max. 0.15 wt. % Fe, max. 0.5 wt. % Mn, max. 1.0 wt. % Zn, max. 0.1 wt. % Ti, max. 0.5 wt. % Ag, the remainder being Al and unavoidable impurities. Also described is a method for producing a light metal tube for a tube of this type configured for example as a bore tube. Said method comprises the steps of forming the light metal tube by means of an extrusion method and subsequent solution annealing, then drawing out the extruded tube over the entire length thereof, until the section or sections having the smallest wall thickness are drawn out by at least 2 to 2.5%, and the drawn light metal tube is artificially aged in a subsequent process step at a temperature of between 164° C. and 180° C.

Abstract: A profile assembly having a first profile and having a second profile connected on its long side to the first profile, which two profiles each have a hook strip integrally formed on the long side, wherein the hook projection of the hook strip of the first profile points in the one direction, and the hook projection of the hook strip of the second profile points in the opposite direction, the hook strips brought into engagement with one another in a claw-like manner. The first profile has an anchoring channel following its longitudinal extent, and the hook strip of the second profile has a clamping strip which is integrally formed thereon, which hook strip is secured by its hook projection and its clamping strip in the anchoring channel of the other profile by a cold joining connection. In order to produce the cold joining connection, one of the two hook strips comprises an adjusting strip which is formed by the cold joining process and which is supported in the produced profile assembly by its free end face while being under prestress. The hook strip secured in the anchoring channel is placed under prestress within the anchoring channel, at two points situated opposite one another in the direction of the height of the profile assembly, with respect to the adjoining portions of the first profile as a result of the cold joining connection.
