How is a groove weld symbol on a drawing interpreted in terms of the weld approach?

• A. It designates only the welding process to use.
• B. It indicates the color of the weld.
• C. It shows the material hardness at the weld.
• D. It specifies the weld type (groove), size, root opening, and any contour or finishing requirements, and is read from the reference line and arrow side.

Answer: (C)

A groove weld symbol tells you exactly how the joint should be built with a groove weld. It specifies the weld type (groove), the size, the root opening, and any contour or finishing requirements, and it is read from the reference line toward the side indicated by the arrow. This notation communicates the geometry and finish the welder must achieve, not the color or hardness of the weld, and not the welding process itself—which is determined by the welding procedure and materials used.
