Which type of weld joint is often used to connect pieces at a right angle?

• A. Fillet joint
• B. Butt joint
• C. T joint
• D. Corner joint

Answer: (A)

The fillet joint is commonly used to connect pieces of metal at a right angle because it allows for the joining of two surfaces that intersect to form a corner. This type of weld is typically triangular in cross-section and is applied to the edges of the materials being joined. It provides good strength and is relatively straightforward to execute, making it a popular choice in various applications. In contexts where pieces meet at right angles, using a fillet joint effectively fills the gap and ensures that the weld penetrates well, leading to a robust connection. This is particularly important in structural applications where the integrity of a right-angle connection is crucial for stability and support. Other joint types have specific uses that might not be ideal for right-angle connections. A butt joint, for instance, is used to join two pieces end-to-end or side-to-side in the same plane, while a T joint typically connects one piece perpendicularly to the center of another, which may not always fit the requirement of a simple right angle, depending on the design. A corner joint is indeed aligned at right angles but is less versatile compared to the fillet joint in terms of the types of positions and load-bearing applications it supports.
