Question

identify this welding joint type:

corner joint
lap joint
butt joint
t-joint
edge joint

Explanation:

Analyze the joint geometry

Using the Welding Joint Types knowledge point
The diagram shows two flat metal plates positioned end-to-end in the same plane with a small gap between them.

Identify the specific joint type

Using the Butt Joint Definition knowledge point
A joint where two members lie approximately in the same plane and are joined at their edges is defined as a butt joint.

Evaluate the incorrect options

• Corner joint: Two members meet at an angle (usually \(90^\circ\)) at their edges to form an L-shape.
• Lap joint: Two overlapping members lie in parallel planes.
• T-joint: Two members meet at approximately \(90^\circ\) to form a T-shape.
• Edge joint: The edges of two or more parallel or nearly parallel members are joined.

Answer:

• (A) Corner joint
• (B) Lap joint
• (C) Butt joint (Correct answer)
• (D) T-joint
• (E) Edge joint
