  • Patent number: 6875942
    Abstract: A method for forming a cylindrical body utilizing a continuous weld is provided. The method includes feeding a source material including a first edge and a second edge from a coil and offsetting at least one of the first edge and the second edge. The method further includes spiraling the material to form a cylinder, welding the first edge and the second edge together forming a continuous weld, and cutting the cylinder to a selected length. To fabricate a jacket, a longitudinal cut is made in the cylindrical body, at least one cutout is cut, and the continuous weld is an outer fillet weld.
    Type: Grant

  • Patent number: 5178317
    Abstract: A method of creating a weld joint between two metal members (B1, B2). The members have coincidentally configured abutting edges (E1, E2), first surface (1A, 1B) which are adjacent to and on one side of the edges, and second surfaces (2A, 2B) which are adjacent to and on the other side of the edges. The method includes chamfering the corners of the respective edges and first surfaces to create a generally V-shaped groove (4) between the first surfaces. A gasket (5) of weld filler material is placed between the edges. The gasket is held between the edges and extends both into the groove and outwardly beyond the second surfaces. The groove is next filled with additional weld filler material (7), and the gasket is then melted and fused with this additional material. The portion of the gasket extending outwardly beyond the respective second surfaces is melted and fused with the edges to form a smooth, continuous surface (8) with the second surfaces.
