Abstract:
A method for bonding metal plates, comprising:overlapping ends of at least two metal plates to provide an overlapped portion having first and second opposed major surfaces;supporting at least the first major surface of the overlapped portion of the metal plates with at least one support;providing at least one shearing blade adjacent the second major surface of the overlapped portion, wherein an extension line of a relative operating locus of the at least one shearing blade crosses the at least one support;moving at least one of the at least one shearing blade and the at least one support towards the other to apply shearing force to the overlapped portion;continuing to move at least one of the at least one shearing blade and the at least one support towards the other to plastically deform the at least two metal plates in the overlapped portion to provide plastically deformed sheared end portions and to press a plastically deformed sheared end portion of one metal plate into a plastically deformed sheared end portion of another metal plate.
