Question

identify this welding joint type:

edge joint
lap joint
t-joint
corner joint
butt joint

Explanation:

Analyze the joint geometry

Using the Welding Joint Types knowledge point
The provided 3D diagram shows two metal plates placed perpendicular to one another. Specifically, the edge of one vertical plate meets the flat surface of a horizontal base plate near its center, forming the shape of the letter "T".

Identify the specific joint type

Using the T-joint Definition knowledge point
A joint formed by placing two members approximately perpendicular to each other in the form of a "T" is defined as a T-joint. Therefore, the correct option is "T-joint".

Answer:

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