Abstract: In a cleaning method for removing adhesive residues from surfaces, in particular after separating an adhesive connection between adhesively joined partners, liquid carbon dioxide from a reservoir enters a jet, apparatus and is guided there through a first dosing unit into an expansion chamber wherein a cold-resistant liquid is then supplied to a mixture created in the expansion chamber from gaseous carbon dioxide and carbon dioxide particles and wherein the mixture, to which the cold-resistant liquid has been added, exits the jet apparatus via an outlet opening thereof. Furthermore, a jet apparatus removes adhesive residues from surfaces.

Abstract: A method for connecting a first element with a second element, includes coupling a third element with the second element, coupling the third element with the first element by thermal joining, wherein the first element and the second element are made of different materials essentially incapable of being thermally joined with a welding process, and wherein the third element is arranged in an opening of the second element in a form fitting and/or force fitting manner.

Abstract: A method for making a vehicle body component includes forming a generally flat plate of unhardened, hot-formable sheet steel with a marginal shape which corresponds essentially to the developed configuration of the finished vehicle body component. The formed plate is hot-formed and hardened in a single press tool to define a sheet profile which corresponds to the configuration of the finished vehicle body component, and a surface coating is applied to the sheet profile.

Abstract: In a method for producing a joint between a hollow profile made from steel and a component made from an aluminum material, a positive and material joint is produced by a braze welding process in conjunction with a pressing operation. The hollow profile is first pressed on a seating region of the component. Subsequently, a weld layer with an additive is applied by thermal joining, producing a positive and material joint between the hollow profile and the component. The positive joint is facilitated by first forming an end of the hollow profile to be pressed on. Preferably, forming is done by widening the end to be pressed on into the shape of a collar.

Abstract: The invention relates to a motor vehicle axle component and a method for producing a motor vehicle axle component. The axle component, for example a dead beam axle, includes a light metal body, such as aluminum or magnesium or corresponding alloys, and a tubular body in form of a steel tube, which are adhesively connected with each other. An adhesive pocket filled with an adhesive is formed between an end of the tubular body and a cylindrical receptacle of the light metal body. Respective bezels are arranged on a free end of the receptacle and on a free end of the tubular body. The spaces between the respective bezels and adjacent walls are filled with adhesive, which seals the interior and exterior transition regions of the joint zone, thus protecting the joint zone against corrosion, improving the load characteristic of the axle component and increasing its service life.

Abstract: A formed component of an automobile and a method for its manufacture are disclosed. The formed component has a base body made of a metal sheet and a smaller, locally arranged reinforcement sheet. The gap between the base body and the reinforcement sheet is sealed in certain areas with a sealing mass made of enamel on an alkali-vanadium-silicate basis. The sealing mass may be applied by screen printing. The sealing mass is dried on the base sheet and/or on the reinforcement sheet, whereafter the reinforcement sheet is attached by welding in a region that is not covered by the sealing mass. The composite sheet formed from the base sheet and the reinforcement sheet is then heated to a forming temperature and hot-formed in a forming tool to the formed component and at least partially hardened.

Abstract: A bumper system for motor vehicles has a cross-member and two crush boxes. The cross-member is made from steel and the crush boxes are made from aluminum, or vice versa. The bumper member that is made from steel has a zinc coating on at least the joint area thereof. A braze weld fixedly connects the crush boxes to the cross-member along associated joints.

Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame. A crash box is incorporated between the cross member and the side rail, with set bolts being provided to join the crash box to the cross member in the absence of prepunching.

Abstract: A method for connecting a tube and a cast component includes widening an end section of the tube to form a widened section, positioning the cast component adjacent to the widened section, and welding the cast component to enclose at least a portion of the widened section with a weld deposit in at least one step, thereby locking the tube and the cast component together. A connection between a tube and a cast component is also provided.

Abstract: In a method of making a subframe of a motor vehicle profile elements made of hollow sections of steel are placed in a casting tool. Subsequently, aluminum material is filled into the casting tool to casting around the profile elements so as to form plural cast nodes on the profile elements in spaced-apart relationship.
