The butt joint with backing weld uses which work angle?

Explanation:
The work angle is how you orient the welding gun relative to the joint surface to control where the molten metal goes and how the bead forms. For a butt joint with backing, you want the electrode held perpendicular to the joint plane, which is a 90° work angle. This directs the filler metal straight into the root and into the backing, producing a clean, square-faced weld with good fusion and penetration. Other angles are used for different joint types or techniques, but 90° works best here to ensure proper root fusion and a solid, even bead.
