ABSTRACT:
A weld joint configuration facilitating the connection of two closely positioned workpieces having spaced apart end surfaces comprising sidewalls of a weld joint space. One of said workpieces has a tongue projecting therefrom that is received at least in part in a groove formed in the other of the workpieces. The interface between the tongue and a surface of the other workpiece partially defining the groove comprises a weld joint parting line. An extension projecting from at least one of the workpieces provides workpiece material located between this parting line and the weld joint space. When the workpieces are welded electrode material and the extensions are mixed to form a composite weld having a root portion with a parting line extending substantially tangentially from the root portion.
