What type of weld is identified by the symbol consisting of two overlapping triangles?

The symbol consisting of two overlapping triangles represents a fillet weld. This type of weld is used to join two surfaces that are at an angle to each other, typically found at the corners of metal structures or components. The shape of the triangles signifies that the weld is applied at the intersection of the two base materials, creating a strong joint that can effectively handle various loads and stresses.

Fillet welds are widely used in construction and manufacturing due to their versatility and the ease with which they can be applied in various positions. Understanding the symbol for fillet welds is critical for interpreting welding plans and ensuring proper execution in fabrication practices. This foundational knowledge is crucial for any welder as it impacts both the integrity of the weld and the overall strength of the welded assembly.
