20100047606 | FRICTION WELDING METHOD AND FRICTION WELDING PART - The invention relates to a friction welding method for the production of a metal bonded joint, wherein two connection parts having contact surfaces are brought into contact with friction pressure. One of the connection parts is moved with respect to the other connection part and, after a time period of friction, the movement is stopped. During a time period of compression, the connection parts are pressed against each other with a compression pressure which is greater than the friction pressure. At least one of the connection parts is constructed of cast iron with nodular graphite (=GJS). | 02-25-2010 |
20090294425 | MAGNETARC WELDING METHOD FOR WORKPIECES WITH OPEN CROSS-SECTIONS - A method for Magnetarc welding for metallic materials wherein at least one of the workpieces to be welded has an open cross-section. The method comprises bracing the two workpieces and moving them together, wherein the open cross-section of one workpiece is bridged by means of a metallic auxiliary part to form a conducting closed region, and after the activation of a magnetic field of a magnet coil system and of the current required for welding, the workpieces are placed with a defined spacing and an electric arc is ignited, the magnetic field of the magnet coil system sets the electric arc in rotation in order to uniformly heat the end surfaces to be welded, and subsequently, the surfaces, which are to be welded, of the workpieces are pressed against one another. | 12-03-2009 |
20080231018 | Fifth Wheel - A fifth wheel comprises a coupling plate and at least two pillow blocks for the supported mounting of the coupling plate on a vehicle chassis of the tractor vehicle, the pillow block comprising a support region and a mounting region. The mounting region is designed for the detachable mounting of the pillow block to a transverse strut of the vehicle chassis of the tractor vehicle. | 09-25-2008 |
