What is a fillet weld characterized by?

A fillet weld is characterized by an approximately triangular cross section that joins two surfaces at right angles. This type of weld is specifically designed to fill the angle between two components that meet, typically joining a plate to a vertical post or another plate. The triangular shape allows for efficient load distribution and provides a strong joint, accommodating the differing thicknesses of materials being joined. Fillet welds can be applied in various configurations, including inside and outside corners, making them versatile for many applications in structural and mechanical engineering. This distinctive shape and functionality make the fillet weld an essential choice in many manufacturing and construction processes.
