Abstract
Peculiarities of plastic deformation and process of hardening in the zone of the joints on commercially pure aluminium AD1 and annealed aluminium alloy 1201AM, explosion welded to high-strength aluminium alloy of the 1201AT type, are considered. To increase the safety factor for ductility of the deformed layers and improve weldability in cladding high-strength aluminium by the explosion welding method, it is recommended to soften the mating surfaces by preliminarily chemically cleaning them from hardening phases.
Keywords: explosion welding, aluminium alloys, weldability, plastic deformation, hardening phases, shear bands, chemical cleaning
