Definition

Joining by forming refers to a range of joining methods which are used to join two or more components by local plastic deformation of at least one joining partner and/or of a joining element.

Theory and Application

Overview

In general, connections generated by forming are created by local plastic deformation of the workpiece and/or the fastener, generating a positive and nonpositive connection between the parts. In addition, residual stresses caused by the joining process can occur in the parts to be joined as well as in the joining element, which can result in traction. Due to the combination of positive and nonpositive locking, high connection strength of the joint is possible (Budde and Pilgrim 1995).

In contrast to welding technologies, usually no heat input and no melting of the materials are required. Accordingly, sometimes this joining method is also referred as “cold joining.” Table 1summarizes the general advantages and...
