In 1F welding, which electrode angle is typical?

In the flat (1F) position, you want a shallow, controlled angle to the joint so the weld puddle forms smoothly and heat is directed where you want it. A typical work angle is about 15° to 25° to the joint line. This keeps the arc focused on the center of the puddle, helps gravity pull the molten metal into place, and produces a good bead with proper fusion and minimal undercut. Angles like 45° or 60° are too steep for the flat position and can lead to an uneven bead, excessive heat concentration on one side, and poorer weld quality. In practice, you’d start around 20° and adjust within the 15°–25° range as needed for the material and speed.
