Joining Methods for Aluminium Sheets

Abstract

Aluminium and its alloys can be joined using various mechanical methods, by adhesive bonding, by welding, or through hybrid (combined) methods. This paper briefly presents methods for joining sheets and flat bars with overlapping edges, including traditional methods such as riveting, resistance spot welding, and cold spot welding, as well as more recent techniques such as cold welding on cogged edges, self-piercing riveting, hybrid joining by welding and self-piercing riveting, and cold spot welding with an interlayer, developed in our laboratories.
