This paper reviews modern meaning, mechanics, and applications of various joining and complex formation especially by plasticity technology. Recently they have come to be recognized as an effective mean for adding value to products as well as a structure-controlled deforming process. As the methods are suited to systems for small-lot production of varied items, they are likely to become even more important for the realization of new multifunctional elements and other purposes. A bond must be sufficiently strong while in use, but the members should be disassembled after use is completed. Modern ideal bonding or complex formation should stand the four essential points; performance of the complex member, simplicity of the bonding method, high bonding strength, and possibility of disassembly.
