Folding is formed by the combination of oxidized surface metals in the process of metal deformation. It can be formed by the confluence of two (or more) strands of metal convection; it can also be formed by the rapid and large flow of one strand of metal which brings the surface metal of the adjacent part to flow, and the confluence of the two; it can also be formed by the bending and refluxing of the deformed metal; it can also be formed by the partial deformation of some metals, which is pressed into another part of the metal.
