Before revision: In warm roll bonding, heat is applied to pre-heat the sheets just before rolling, in order to increase their ductility and improve the strenght of the weld .The strength of the rolled bonds clearly depends on the main process parameters, including the rolling conditions (entry temperature of the sheets, amount of thickness reduction, rolling speed, etc.
