20080290143 | Method of Solid Phase Welding of Metal Plates - In a method of welding of metal plates in a solid phase, wherein the metal plates are combined to form a package, and welded together by heating and deforming the package by contacting with two rotating cylinders, the improvement includes: providing a damping lining between the metal plates; placing the package between two cylinders such that the metal plate with the smallest yield value under welding temperature faces the cylinder with smaller diameter, heating and deforming the package in vacuum, such that during a first stage the temperature reaches 0.4-0.5 of melting temperature of a metal plate with the smallest yield value, during a second stage the package is heated by a high frequency which heats the damping lining up to 0.92-0.95 of its melting temperature, wherein angular velocities of the rotating cylinders and their radiuses are selected in accordance with a formula. | 11-27-2008 |
20110114709 | METHOD FOR ACCUMULATING FOIL IN A WELDING PROCESS - The present invention relates to a method for welding at least one foil in a packaging process using a welding assembly, comprising the steps of directing the foil into the welding assembly, holding the foil in at least one holding point of the welding assembly, welding the foil in at least one welding point of the welding assembly, and where a part of the foil is accumulated between the at least one holding point and the at least one welding point prior to welding the foil in the welding point. The present invention further relates to a welding assembly employing this method. | 05-19-2011 |
20110174869 | JOINING METHOD OF HIGH CARBON STEEL FOR ENDLESS HOT ROLLING AND THE APPARATUS THEREFOR - An endless hot rolling material shear-joining method capable of threading hot rolling materials in a finish rolling process without strip breakage by controlling joining conditions for the hot rolling materials in an endless hot rolling process for high carbon steel, and an endless hot rolling plant therefor are disclosed. The shear-joining method for endless hot rolling materials of high carbon steel includes shear-joining high carbon steel metal bars comprising, in terms of weight %, 0.30% to 1.20% C, inevitable impurities, and balance Fe, or comprising 0.15% to 1.5% C containing at least one of Cr, Ni, Mo, V, Ti, W, B, Nb, and Sb, inevitable impurities, and balance Fe, such that a joined surface of the joined metal bars is formed to be inclined in a thickness direction of the metal bars, in a hot rolling plant by a joiner adapted to join the metal bars after overlapping tail part of a leading one of the metal bar and top part of a trailing metal bar. | 07-21-2011 |
