Patent number: 8042368Abstract: To produce hollow profiles from sheet-metal blanks, the invention uses at least two process steps to form said blanks into a slit profile which is subsequently welded to produce the finished welded profile. For this purpose a mandrel is used which cooperates with a first tool part in the first step, and with a second tool part in the second step, such as to form a gap with the recess of each tool part into which a portion of the sheet-metal blank is guided. Shaping the sheet-metal blank in at least two steps means that a mandrel that is a self-contained component and can therefore be moved by a simple control device can be used to support the sheet-metal blank while the slit profile is being created. This considerably reduces the equipment needed to produce the hollow profile. Moreover, forming the sheet-metal blank into the slit profile in at least two steps also considerably improves the reliability with which this shaping takes place.Type: GrantFiled: August 20, 2005Date of Patent: October 25, 2011Assignee: ThyssenKrupp Steel AGInventors: Michael Brüggenbrock, Thomas Flehmig, Wladimir Rituper, Mohamed Tohfa

Patent number: 7752728Abstract: A material composite has a part made from steel or a titanium-based material and a part made from a copper-based or aluminum-based material. The parts of the material composite are joined by way of an intermediate piece. The intermediate piece likewise comprises a region made from steel or a titanium-based material and a region made from a copper-based or aluminum-based material, which are connected by explosion welding. The parts of the material composite are connected to the regions of the intermediate piece which are in each case of the same type by means of a fusion or diffusion welding process.Type: GrantFiled: September 11, 2006Date of Patent: July 13, 2010Assignee: Plansee SEInventors: Bertram Schedler, Thomas Huber, Thomas Friedrich, Karlheinz Scheiber, Dietmar Schedle, Anton Zabernig, Hans-Dieter Friedle, Sandra Mair, Nadine Wörle

Publication number: 20100170320Abstract: A method for manufacturing a high alloy pipe comprises hot working, a high alloy material pipe having controlled amounts of C, Si, Mn, P, S, Ni, Cr, Mo, Cu, Al, N, O, and optionally Ca, Mg, and rare earth elements, with the balance Fe. The pipe composition satisfies the formula N×O?0.001. The pipe is subjected to cold working to form the high alloy pipe, wherein the final cold working process is performed under the condition that a working ratio Rd in the reduction of area satisfies 15?Rd(%)?370×(C+N), where N, O and C are the contents (by mass percent) of the respective elements, and Rd is the working ratio (%) in the reduction of area. The pipe has an excellent ductility and an excellent corrosion resistance when cold working is performed to obtain a high strength after pipe-making.Type: ApplicationFiled: December 31, 2009Publication date: July 8, 2010Inventors: Masayuki Sagara, Hitoshi Suwabe, Hisashi Amaya, Shigemitsu Kimura, Masaaki Igarashi
