Abstract
A method of welding in which an edge portion of a first panel is placed over an edge portion of a second panel, with an outer edge of the edge portion of the first panel adjacent to a shoulder of the second panel to provide a joint between the outer edge and the shoulder. Spot welds are applied to the panels along the joint by a bronze metal inert gas (MIG) welding gun. Pressure applied by a pressure applicator alongside the MIG welding gun presses the edge portions of the panels together during the spot welding. Linear MIG weld segments are then applied along the joint between the spot welds by the MIG welding gun to form a continuous line of MIG welding. The continuous line of MIG welding is polished to remove irregularities so that it blends evenly and smoothly with the panels.
