In the matching exercise, which number corresponds to Weld All Around?

• A. 1
• B. 2
• C. 4
• D. 3

Answer: (D)

Weld All Around is shown when the weld runs completely around the joint’s circumference. The symbol for this is a circle placed on the weld reference line, indicating the weld encircles the joint rather than stopping at a point or running in a limited arc. In the matching task, the option that uses that circular, all-around indication is the one that matches Weld All Around. Other options depict welds that do not encircle the joint (they show partial lengths or different weld forms), so they aren’t a match for this type.
