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. Forming of this latter smooth, continuous surface is accomplished without the use of any additional weld filler material.
