Abstract: A liquid phase diffusion bonding method for a metal machine part superior in the quality of the joint and the productivity enabling the bonding time to be shortened, achieving homogenization of the bonding structure and improving the tensile strength, fatigue strength, and joint quality and reliability. This liquid phase diffusion bonding method of a metal machine part is characterized in terposing an amorphous alloy foil for liquid phase diffusion bonding at bevel faces of metal materials, performing primary bonding by melt bonding said amorphous alloy foil and said metal material by resistance welding to form a joint, then performing secondary bonding by liquid phase diffusion bonding by reheating said joint to at least the melting point of said amorphous alloy foil, then holding it there to complete the solidification process of said joint.

Abstract: Catalytic converter (2) includes a catalyst container (10) formed from a tubular blank (10') and having a catalyst carrier, and a flange member (11) joined to the hollow member. The tubular blank (10') is subjected to a spinning operation by forming roll or rolls (22A), to form the catalyst container (10) having a desired shape, and the opposed circumferential surfaces of the catalyst container (10) and flange member (11) are forced against each other by the forming roll or rolls (22A) or an array of presser pieces (22B) while the catalyst container and flange member are rotated relatively to each other, so that friction heat is generated for friction-welding the catalyst container and flange member at their joining portions (10b, 11b).

Abstract: The invention relates to a method for producing a steering tie-rod housing, consisting of a steering tie-rod head (1) with a shaft element (2) fixed thereto. According to said method, the steering tie-rod head (1) receives its final construction form in a mechanical machining process after the production of the steering tie-rod head blank consisting of the shaft element (2) and the steering tie-rod head (1), The shaft element (2) is joined to the steering tie-rod head (1) by means of a resistance welding operation and at least two material accumulations (8, 9), which interconnect the two components are subsequently formed between the external peripheral surface of the steering tie-rod head (1) and the shaft element (2) by means of a welding operation.

Abstract: The invention relates to a device and a method for producing nozzle-type openings in spray arms for dishwasher machines, which enable the form of the nozzle-type openings in the spray arms to alter rapidly even if only one spray arm is provided, and enable different nozzle geometries to be created during the production process in the event of different spray arms. According to the inventive method for producing nozzle-type openings in spray arms for dishwasher machines, once the spray arm blank has been produced, nozzle-type openings with different designs are cut out of the surface of the spray arm blank by means of a laser beam.

Abstract: The invention relates to a gas exchange valve with a hollow space, for an internal combustion engine. Said valve comprises a valve stem (3), a valve base and a valve disk (2). The valve stem and valve disk or valve stem and valve base have an approximately cylindrical, elongated hollow space which is formed by both parts. Said space is sealed by welding. The aim of the invention is to improve the quality of the welding. To this end, an extra mass of the material required for sealing the hollow space is provided on the valve disk or the valve base so that no additional welding material is necessary.
