Which weld joint is used to join a solid round bar to a plate with flush welds on both sides along its length?

• A. A flare V-groove weld.
• B. A double bevel groove weld.
• C. A flare bevel groove weld.
• D. A double flare bevel groove weld.

Answer: (D)

To join a solid round bar to a plate and have flush welds on both sides along the length, you need a groove geometry that lets you weld from both sides and around the bar. A double flare bevel groove weld provides two bevels, one on each side, with the flare open enough to expose the root and allow full fusion as you lay weld beads on both sides. This setup enables two continuous weld paths, resulting in flush surfaces along the entire length of the bar. Other groove configurations don’t give you the same dual-side access along the length. A single flare bevel groove would only provide access from one side, and other options don’t naturally create two accessible root openings on opposite sides for the bar, making it harder to achieve flush welds on both sides along the length.
