For a visual inspection, an open butt joint weld must be completely what?

Explanation:
When inspecting an open butt joint, the weld must be completely filled so there are no voids at the root of the joint. This full fill ensures the two pieces have been fused along the entire joint width, providing the necessary cross‑section strength and a smooth surface for finishing. If the weld is not fully filled, a root void or gap remains that weakens the joint and can trap moisture or promote cracking under load. While cracks, undercut, and porosity are also defects, the specific requirement for an open butt joint is that the weld be completely filled.
