It uses two electrodes in spot welding, where the tip of the electrode produces heat and fusion when cooled. It is known to be an efficient welding process as it is pollution free with minimum power consumption. Resistance welding is the process of joining metal in which pressure and current are passed over a long period through the metal area to be joined. The following are types of welding processes according to the method of heat generated: Read Also: How Does UnderWater Welding Works? and Types of Underwater Welding Types of Welding Processes So, let’s discuss the different types of welding processes and how they are used in Industries. The temperature of the heat produced is of the order of 6000° to 7000°c. ![]() The filler metal is supplied to form the joint, either from the electrode itself (or) by filler material. ![]() Welding MachineĪ welding machineis used to create the heat and apply the filler metal. In general, it is a process in which two metal pieces similar (or) dissimilar may be joined by heating them to a temperature high enough to fuse the metals with (or) without the application of pressure and with (or) without the aid of filler material.
