Question: An apprentice welder is reviewing a shop drawing for a pressure vessel component. A callout indicates a 'Double-V Groove Weld' with a preparation depth of 12 mm (1/2 in.) on each side. Which weld symbol accurately depicts this requirement?

Answer options: ✅ Two V-groove symbols, one above and one below the reference line, each with '12' to the left.

• A single V-groove symbol with '24' to the left, and a field weld flag.
• A U-groove symbol above and below the reference line with '12' to the left of each.
• A bevel-groove symbol above and below the reference line with '12' to the left of each.

Correct answer: Two V-groove symbols, one above and one below the reference line, each with '12' to the left.

Explanation: A double-V groove weld is represented by two V-groove symbols, one offset above the reference line (other side) and one below (arrow side). The number '12' to the left of each symbol consistently indicates the specified depth of preparation for each side. Distractors represent incorrect weld types or measurement indicators.
