Which weld type is used in joining a solid round bar to plate, filled flush on both sides down 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: (C)

When joining a solid round bar to a plate along its length, you want a groove that wraps around the bar and allows filler metal to fill the joint evenly along the whole seam, producing a flush weld on both faces. The flare bevel groove weld provides that geometry: the plate is beveled and widened toward the surface (flare), creating an opening around the round bar so weld metal can flow and fill from the root around the circumference as you traverse the joint. This setup enables full fusion and a smooth, flush finish on both sides along the entire length. Other groove types don’t offer the same combination of accessibility around a round member and the ability to finish flush along the length, making the flare bevel groove weld the best fit for this joint.
