Fillet welding is most productive in the flat position, where the joint sits horizontal and you weld from above. In this setup, gravity helps the molten metal stay in the joint and form a stable bead, which makes it easier to control the weld pool and move quickly along the joint. The torch and filler wire are easier to handle, you get better visibility of the weld pool, and you can maintain a consistent bead size with fewer interruptions to adjust angle or position. In horizontal, vertical, or overhead positions, gravity works against you, causing sagging or run-off and requiring slower, more careful manipulation to avoid defects. So the flat, or flat-fillet, position offers the most efficient, productive welds.
