Positions are classified based on plate (groove/fillet) and pipe: welding position
career role within the industry. 1. Common Welding Orientations Welders typically use five primary positions to describe how the joint is placed relative to the welder. These are often categorized by number (1-4) and weld type (F for Fillet, G for Groove): Miller Welding +1 Flat (1G / 1F): The easiest position; the weld is performed on the top side of a joint. Horizontal (2G / 2F): The weld axis is horizontal, requiring the welder to manage the molten pool against gravity. Vertical (3G / 3F): The weld is performed on a vertical surface, moving either upward or downward. Overhead (4G / 4F): The most difficult position; the weld is performed from the underside of the joint. Inclined (6G): Primarily used for pipe welding; the pipe is fixed at a 45-degree angle, requiring the welder to use all the positions above in a single pass. Miller Welding +2 2.
