Purpose - To review the capabilities of a new method of
welding aluminium sheets for car body construction. Design/methodology/approach - Describes the
friction spot joining technique, and how it differs from friction stir welding. Describes the
tests carried out at the University of Warwick to compare this with other aluminium sheet joining
techniques. Findings - Compared with resistance spot welding, this technique is simple, and
physically and electromagnetically clean. Its low energy requirement per joint and low running
costs give it advantages in joining thin materials, and eventual recycling is much easier than
with self-piercing riveting joints. Originality/value - Describes the motivation behind the
continuing development of an all-aluminium joining technique, and compares spot friction joining
with self-pierce riveting and resistance spot welding.
