ABSTRACT:
A coherent bond is formed for thin metallic sheets by hot press welding an auxiliary deformable material to the sheets to be bonded together. During application of a force to the deformable material, the oxide layer on the metallic structural elements is physically moved by the deformation of the auxiliary deformable material. In this manner, the auxiliary deformable material is directly bonded to clean metal and is built into the crystalline lattice structure of the thin metallic elements to thereby produce a coherent bond.
