Which of the following is a common groove weld bevel type?

• A. Fillet weld
• B. U-groove
• C. J-groove
• D. V-groove

Answer: (D)

Groove welds are used on butt joints where the edges are prepared to form a groove so the weld metal can fill it and fuse both sides for a strong root. Among the options, the V-shaped bevel stands out as a common choice because it creates a symmetric groove that provides easy access for welding from both sides and typically gives good root penetration across a wide range of plate thicknesses. The geometry is straightforward to prepare, and it tends to produce a reliable, balanced weld profile with repeatable results.

By contrast, a fillet weld does not involve beveling the edge to form a groove; it fills an intersection on corners or T joints and produces a triangular cross-section, not a groove at the root. U-groove and J-groove are also groove types, but they are used in more specialized cases and are less common for general applications compared with the classic V-groove.
