Abstract: A ferrous or like metal coupling or other metal attachment, such as a heady round lug, includes a generally cylindrical body having a beveled base and a divider land or keel extends diametrically across the base and projects downwardly therefrom and divides the beveled base into two generally coequal component weld surface areas on opposite sides of the divider land or keel. The body of the metal coupling or other metal attachment, such as a heady round metal lug, is positioned at a desired and preselected point on the external surface of a metal pipe or tube whereupon the metal coupling or other metal attachment is preliminarily or tack-welded to join the divider land or keel to the external surface of the metal pipe or tube. The metal pipe or tube with the metal coupling, or other metal attachment, thus preliminarily or tack-welded thereto is then rotated alternately, or back and forth, to position each of the component weld surface areas in a generally vertical plane, and with the axis and progression of the weld in a generally horizontal plane, with weld metal being applied generally from above, first in one of the component weld surface areas and then in the other component weld surface area, and this operation is repeated or continued in successive steps or passes with additional weld metal being applied in increments at each successive step or pass until the welding of the metal coupling, or other metal attachment, to the metal pipe or tube has been completed.
