Abstract:
1. A threaded weld fitting configured to be aligned with an opening defined in a tank wall and welded to the tank wall to form a water heater tank weldment, the threaded weld fitting comprising: a body defining an aperture along a longitudinal axis of the body and having a facing surface configured to be positioned facing the tank wall; a female thread formed along at least a portion of the aperture and configured for threadedly receiving a male thread of a mating part; a weld projection defined on the facing surface of the body and including an edge configured to be positioned against the tank wall; a first beveled surface portion of the facing surface extending from the edge of the weld projection; a landing surface portion of the facing surface extending from the first beveled surface portion toward the longitudinal axis of the body, the landing surface portion being oriented at an angle with respect to the first beveled surface portion and substantially orthogonal to the longitudinal axis of the body; and a second beveled surface portion of the facing surface extending from the landing surface and to the female thread; wherein the landing surface portion and the second beveled surface portion of the facing surface together define an open annular area positioned to receive a portion of a weld formed by welding the threaded weld fitting to the tank wall; and wherein the first beveled surface portion is oriented at a first angle with respect to the longitudinal axis of the body and the second beveled surface portion is oriented at a second angle with respect to the longitudinal axis of the body, the first and second angles being different from one another.
