This paper describes the work carried out by Alcan International Ltd. and BL Technology to investigate the possibility of introducing weld-bonded aluminium structures into volume car production. It has been established that such structures are stiffness rather than strength limited, so the use of readily available medium strength Al-Mg alloys has been shown to be possible. The technology depended on the development of a coil product which is pretreated and prelubricated in coil form. Pretreatment, lubricant and adhesive must all be compatible, so components can be press-formed from the coil product and weld-bonded without any intermediate cleaning stage. Such a processing route has been developed and some of the critical requirements of the alloy, pretreatment, lubricant and adhesive are discussed. A major factor in the work was the necessity of establishing methods of evaluation for the bond strength and durability of the system proposed, and this is described.
