Question

quiz
question 3 of 10
identify this welding joint type:
butt joint
edge joint
t-joint
lap joint
corner joint

Explanation:

Analyze the joint geometry

Using the Welding Joint Types and Butt Joint Definition knowledge points

The diagram shows two flat metal plates positioned end-to-end in the same plane. The edges of the two plates face each other with a small gap between them. This specific alignment where two members lie in approximately the same plane and are joined at their edges is the definition of a butt joint.

Evaluate the options

Using the Welding Joint Types knowledge point

• Butt joint: Correct. The plates are aligned end-to-end in a single plane.
• Edge joint: Incorrect. An edge joint involves plates placed parallel with their edges even.
• T-joint: Incorrect. A T-joint forms a 'T' shape where one plate is perpendicular to the other.
• Lap joint: Incorrect. A lap joint consists of two overlapping plates.
• Corner joint: Incorrect. A corner joint joins two plates at a right angle at their outer edges.

Answer:

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