Structural Welding positions

There are four basic welding positions, or orientations, that have been defined by the American Welding Society. They are Flat-(1), Horizontal-(2), Vertical-(3), and Overhead-(4). These positions are designated by the number that relates to the position followed by a letter that designates the type of weld; (F) for fillet weld, and (G) for groove weld.
