What is the work angle in welding?

• A. The angle the electrode makes along the weld
• B. The angle the electrode makes in the plane at right angles to the weld
• C. The angle the electrode makes in the plane of the heat source
• D. The angle of travel along the weld

Answer: (B)

The work angle is how the electrode is oriented across the joint, measured in the plane at right angles to the weld. This perpendicular tilt determines how the molten metal interacts with the sides of the joint, influencing bead shape and penetration by guiding the arc and heat where it contacts the work area. It differs from the travel angle, which is the tilt along the direction you’re welding. Tilting along the weld direction affects travel, while tilting in the plane perpendicular to the weld is what sets the work angle.
