Patent number: 7735705Abstract: Device for joining faces of parts having great longitudinal extension by friction welding. The device includes first and second clamping arrangements structured and arranged to position ends of the parts against one another. At least one of the first and second clamping arrangements is axially movable with respect to another of the first and second clamping arrangements. At least one of the first and second clamping arrangements is movable along a direction that is parallel to a part cross-sectional plane defined by an end face of one of the parts.Type: GrantFiled: November 25, 2008Date of Patent: June 15, 2010Assignee: voestalpine Schienen GmbHInventor: Hans Pfeiler

Patent number: 7267258Abstract: The process for metallically connecting the faces of rods. Axially normal dressing at least two rod free ends, then placing the cross sectional surfaces of the rod free ends one against another under pressure. Oscillating the two rod free ends in the opposite direction to one another, whereby frictional heat is generated on the contact surfaces of the rod free ends. Further, when the conditions for a metallic connection are met, the rod free ends are axially aligned and the pressurization of the cross sectional areas is increased. Resulting in the rod free ends being connected to one another over the entire surface. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.Type: GrantFiled: March 29, 2005Date of Patent: September 11, 2007Assignee: voestalpine Schienen GmbHInventor: Hans Pfeiler

Publication number: 20040256439Abstract: The invention relates to a device and a method for the axially aligned joining of long parts, in particular rails, by friction welding. It is provided according to the invention that the friction welding device (A) features clamping means (2, 2′) for the part ends (11, 11′) that can be positioned against one another and at least one clamping means can be moved relative to the opposite one, parallel to the part cross-sectional plane (12, 12′) in an axially divergent manner and can be positioned in an axially aligned manner to the part with freedom of movement.Type: ApplicationFiled: March 19, 2004Publication date: December 23, 2004Applicant: Voestalpine Schienen GmbHInventor: Hans Pfeiler
