    Abstract: The invention relates to a method of making a steel Yankee cylinder 1 by welding a cylindrical shell 2 to two end walls 3, 4 such that the cylindrical shell 2 and the end walls 3,4 together form the Yankee cylinder 1. The welding operation is carried out exclusively from the outside of the Yankee cylinder 1 and in the welding operation is carried out as a butt welding operation in which a backing material 7 is used on the inside of the Yankee cylinder 1 such that, between each end wall 3, 4 and the cylindrical shell 1, a single weld bead 8 is formed which extends all the way between the opposing surfaces 5, 6 and completely fuses the opposing surfaces 5, 6 of each end wall 3, 4 and the cylindrical shell 2 respectively.

    Abstract: A retention clip used to retain workpieces during welding includes a spacer that extends along an axis and a plurality of first and second spring members positioned on opposite sides of the axis. The first spring members may be spaced apart from each other along the axis and configured to constrain a portion of a first workpiece between the first spring members and the spacer. And, the second spring members may be spaced apart from each other along the axis and configured to constrain a portion of a second workpiece between the second spring members and the spacer.

    Abstract: The objective of the present invention is to provide a similar-metal-composition welding solid wire, and weld metals therefor, with which both excellent bead shape and high ultralow-temperature toughness for the weld joints can be achieved when welding 9% Ni steels together by means of a high-efficiency MIG welding method. A fixed ratio of a REM and O are included in a similar-metal-composition welding solid wire of a 9% NI steel base material, and oxygen is supplied in a trace amount in a range that does not hinder the ultralow-temperature toughness of the weld joint (1a) but that is capable of forming fine REM oxides in the weld metal (3) and of controlling the weld metal to produce an excellent bead shape. In addition, both Al and Ti are regulated and an argon gas that contains little or no carbon dioxide gas is used as the shield gas in the MIG welding method. Thus, both an excellent bead shape and high ultralow-temperature toughness for the weld joint (1a) can be achieved.

    Abstract: A method of gas shielded arc welding steel railroad rails spaced from each other to define a longitudinal gap comprises the steps of providing an elongated steel barrier plate across the gap at the bottom of the spaced rails, and filling gap above the barrier plate with a molten steel from an advancing filler metal electrode by a gas shielded electric arc welding process. The barrier plate has a central portion received in the gap and longitudinally extending recesses laterally outwardly adjacent to the central portion and which underlie the bottoms of the rails at the bottom of the gap.

    Abstract: To provide a material to be welded for butt welding which can reduce contamination of particles into a welded portion after the welding is executed and which can construct piping or a device each enabling realization with high repeatability a ultra-clean atmosphere in which the density of impurity such as moisture or the like is suppressed, and a method of cutting the same. Also to provide a wire used for wire cut electric discharge machine which can prevent reduction of chromium composition in a place adjacent to the welded bead section after the welding is executed. (1) A face to be butted of the material to be welded is cut by a wire cut electric discharge machine. It should be noted that it is preferable that the surface of the wire used for the wire cut electric discharge machine is stainless or chromium and that stainless steel or chromium having a thickness of not less than 0.1 .mu.m is deposited on the cut face. (2) As for the method of cutting, at least a face to be butted is cut by the wire cut electric discharge machine. (3) At least the surface of the wire is made of stainless steel or chromium.
