How is pressure welding carried out?How is pressure welding carried out?Pressure welding can be carried out by several welding methods which have in common the fact that the surfaces of the joint are pressed or worked together. Smiths in traditional forges used forge welding, which involved heating metal pieces in a fire until they became plastic and then forged them together.Pressure Welding - an overview ScienceDirect Topics Images of Pressure Welded

Resistance Welding - an overview ScienceDirect Topics

Resistance welding involves passing an electric current through the components being joined to heat the interface enough to cause melting of the materials at the interface. No filler material is used. A clamping force, which is applied during the heating process, holds Resistance Welding - an overview ScienceDirect TopicsThe simplest form of the process is spot welding where the pressure is provided by clamping two or more overlapping sheets between two electrodes (Fig. 9.1).A current is then passed between the electrodes, sufficient heat being generated at the interface by resistance to the flow of the current that melting occurs, a weld nugget is formed and an autogenous fusion weld is made between the plates.
