    Abstract: A clamping mechanism in a diffusion bonding apparatus comprising a first clamping section which clamps the vinicity of the end of a material to be bonded, and a second clamping section which is further from the end of the material and clamps the material in that position; wherein the first clamping section prevents deformation in the ends of the materials to be bonded, while the second clamping section clamps the material in order to obtain predetermined pressure at the bonding part of the materials.

    Abstract: Apparatus (10) and method of forming a deep sea pipeline or a cross country pipeline by welding pipes together to form the pipeline. Two pipes (2, 4) are arranged so that their ends (26, 27) define a circumferentially extending narrow angled (less than 10 degrees) groove (28). At least two arc welding torches (1) are arranged directly adjacent to each other on a single carriage that moves around the pipes, to form a twin arc welding system. The arcs of the torches (1) form a weld (3) in the groove. The carriage is moved around the pipe, the torches thus moving around the pipe with the same speed. Each torch (1) is independently oscillated so that the position of its arc oscillates between the walls of the groove. The arcs are guided automatically by an electronic guidance system, wherein electrical characteristics (such as arc current or voltage) of the welding of each torch (1) with regard to each pipe (2, 4), respectively, are ascertained and a comparison made between the electrical characteristics relating to one of the pipes with the corresponding electrical characteristics relating to the other of the pipes. The position of an arc of a torch (1) may thus be aligned with the centre line of the groove (28).

    Abstract: A high strength clad material having excellent moldability, specifically a three-layered clad material produced by using a stainless steel as a substrate and integrating a sheet of nickel or its alloy with one principal plane of the substrate and a sheet of copper with the other principal plane of the substrate both by pressure welding or a two- or three-layered clad material produced by integrating a sheet of nickel or its alloy with at least one principal plane of the substrate by pressure welding. The clad material makes it possible to further increase the relative thickness of the stainless steel, while reducing the total thickness of the clad material, thus realizing a mechanical strength (tensile strength) at least equivalent to that of the conventional two- or three-layered clad material. A tension bridle roll having a predetermined size and shape is disposed on the feed side of a pressure welding roll and a sheet of nickel, copper, etc., is fed to the pressure welding roll through the tension bridle roll, thus making it possible to apply a uniform tension to each sheet as a whole, to prevent the occurrence of breakage and wrinkles during the pressure welding, to reduce the thicknesses of both nickel and copper sheets before pressure welding to about 5 νm, and to reduce the relative thickness of each sheet in the three-layered clad material for a battery case to about 0.5 % of the total thickness.
