What does the weld symbol represented by a right-angle triangle indicate?

The weld symbol depicted by a right-angle triangle signifies a fillet weld. This type of weld is characterized by its triangular cross-section, which allows it to join two surfaces at a right angle or on the same plane. Fillet welds are versatile and commonly used in construction and manufacturing, particularly for joints that are not in line or where parts meet at an angle.

The triangle shape effectively indicates the profile of the weld that will be applied to the joint, emphasizing its purpose to fill the gap between the pieces being joined. The triangle serves as a visual shorthand in welding blueprints, providing essential information about how the weld is to be executed, the size, and often the dimensions necessary for the welding operation.

Understanding this symbol is crucial for those in the welding and piping industry, as it ensures clarity and precision in the execution of welding tasks and helps maintain the integrity of the structures they are assembling or repairing.
