Question

introduction to welding: weld types, positions, and symbols

quiz

question 5 of 10

identify this welding joint type:

t-joint
edge joint
corner joint
butt joint
lap joint

Explanation:

Analyze the geometry of the joint

The diagram shows two metal plates placed side-by-side with their edges flanged upward. The parallel edges of the two sheets are aligned adjacent to each other, forming a joint where the weld will be deposited along the common outer edges.

Match with standard joint definitions

• A T-joint consists of two members meeting at approximately \(90^\circ\) in the shape of a 'T'.
• A Corner joint consists of two members meeting at their edges at approximately \(90^\circ\) to form an 'L' shape.
• A Butt joint consists of two members lying in the same plane with their ends aligned.
• A Lap joint consists of two overlapping members.
• An Edge joint is formed when the surfaces of two or more parallel or nearly parallel members are joined at their adjacent edges. The flanged sheets in the diagram meet edge-to-edge along parallel planes, which is a classic flanged edge joint configuration.

Answer:

• T-joint
• Edge joint (Correct answer)
• Corner joint
• Butt joint
• Lap joint
