What is a fillet seal?

A fillet seal is a type of seal used in mechanical and structural applications, typically formed at the junction of two surfaces, such as in welding or adhesive bonding. It features a rounded or curved profile, which helps distribute stress more evenly and can improve the overall strength and durability of the joint. Fillet seals are commonly found in various industries, including construction, automotive, and aerospace, where they enhance the integrity of assemblies.
