Abstract: Sections 1 and 2 each in the form of a welded pipe (square pipe) are provided. The sections 1 and 2 are brought into abutment with each other so that the respective end faces 3a and 3b abut each other at a predetermined angle .beta. between each section and its axial direction. The sections 1 and 2 are arranged symmetrically with respect to each other. Acute end portions of the abutted portion are chamfered to from a plane part. Corners of the sections 1 and 2 are rounded. In such a combined state of both sections, the abutted portion is welded in the circumferential direction to form a weld bead. As a result, penetration of weld metal to the section 1 and that to the section 2 become equal to each other. Thus, it becomes possible to fabricate a welded structure having a uniform weld bead and having improved strength and reliability of welded portions.

Abstract: An elongate flexible clamp mechanism defines first and second ends and is capable of assume a substantially flat configuration and is capable of being positioned in encircling relation about a cylindrical object such as a pipe. A pair of elongate flexible members such as wire cables, chains or pivotally interconnected rigid members support a plurality of substantially rigid clamping members in spaced relation along the lengths of said elongate flexible members. The clamping members are each provided with jack screws for force applying engagement with the pipe to enable alignment of adjacent pipe sections and to correct minor irregularities in pipe roundness so that adjacent pipe sections can be efficiently welded. The elongate flexible clamp mechanism is provided with first and second latch connector elements which are interconnected when the clamp mechanism is located in encircling relation about the pipe. The latch mechanism is of the cam or toggle type, enabling the clamp mechanism to be tightened about the pipe. Jack screws are also provided on each of the clamping elements to permit jacking force to be applied to the pipe for optimum pipe alignment and for correction of minor irregularities in pipe roundness.

Abstract: A method is disclosed for applying a weld overlay to a tube. Using a first weld head, a bead of overlay material is applied onto a tube by melting the overlay material. In the process of applying the weld bead to the tube, a heat affected zone is created within the tube. Thereafter, a second weld head is employed to apply sufficient heat to the exterior of the tube to raise the temperature within the heat-affected zone to a temperature higher than its tempering temperature but lower than its Ae1 temperature. In this manner the heat affected zone is eliminated without creating a new heat affected zone in the process.In the disclosed embodiment, the tube is rotated with respect to the weld heads, while the weld heads move along the longitudinal axis of the tube. According to the disclosed embodiment, the first weld head employs a gas-metal arc welding process, and the second weld head employs a gas-tungsten arc welding process.

Abstract: A three dimensional flame nozzle on which at least four conduits stand upright. Each conduit has at least upper and lower nozzle tips. The angles of each nozzle tip can be adjusted so that a flame blown from each nozzle tip intersects with the flame blown from a corresponding nozzle tip to form a three dimensional flame having a number-sign shape that is steady and focused near the central portion of reinforcement steel. A nozzle supporting fixture has a first hold fitting to firmly hold and release the reinforcing steel at one end of a nearly L-shaped nozzle supporting fixture and a second hold fitting to firmly hold and release a three-dimensional nozzle at the other end of the L-shaped nozzle supporting fixture.

Abstract: A process for the manufacture of cladded metal pipes facilitates joining of a tube blank and a coaxially disposed pipe section received therein, for subsequent extrusion of a resultant tube blank-pipe combination to form an internally-clad pipe of desired dimension. The pipe section, which is inserted into the tube blank, is expanded radially by internally directed pressure, while force is axially applied to maintain the expansion of the pipe section following removal of the applied internal pressure and axial force. A mechanically joined tube blank-pipe combination thus formed is extruded to form a finished pipe of desired profile in which a diffusion bond is present between material layers comprising the internally-clad pipe corresponding to the pipe section and the tube blank.
