Cold roll bonding of 5754-aluminum strips

An approach for calculating weld efficiency from the results of a peel test has been developed for 5754-aluminum strips. The method is based on estimating the effective load-bearing area of peel test specimens. A convincing agreement between the results and the theoretical model—earlier developed by Wright et al. (Metals Technol. 5 (1978) 24)—has been found. The influence of surface expansion and rolling pressure on the weld efficiency has been studied by the new approach.
