Cold pressure welding
Most welding methods involve the use either of heat alone (fusion welding) or a combi-
nation of heat and pressure. Cold pressure welding is an example of a welding method
that is carried out entirely without heating. The principle involves pressing the parts of
the workpiece together with such force that plastic deformation causes any residual
oxide layers to be pressed out and a metallic bond to be made. The method is very suit-
able for use with copper and aluminium, and is often used for electrical connections. An
example is the connection terminal of copper which can be cold pressure-welded to
aluminium conductors.
