Generally, bonding refers to joining of two materials surface-to-surface, in a manner in which one covers the other, as opposed to fastening, where members are joined at a discrete point. Cladding, in which one material covers another entirely and pressure and/or heat is applied to create the bond between them, is a form of bonding. Welding and Brazing are both bonding processes.
