Resistance welding
Resistance welding. Resistance welding is a process in which heat is generated at the interface by passing an electric current through it. It is performed under control time and pressure. The term is derived from the fact that the resistance between the workpiece and electrodes are used to generate the heat at the interface.

Resistance Welding Fundamentals
The general heat generation formula for resistance welding is: Heat = I2 x R x t x K. Where "I" is the weld current through the workpieces, "R" is the electrical resistance (in ohms) of the workpieces, "t" is the weld time (in hertz, milliseconds or microseconds), and "K" is a thermal constant. The weld current (I) and duration ...

What is Resistance Welding?
Resistance welding is generally used to join two plain metal work pieces together. An electric current is delivered to the metal sheets (or any work pieces being joined) through weld electrodes which apply force to the sheets. This force is then converted to heat. The heat is generated so that it melts the metal at the point where they join ...
Fact Sheet No. 21
INTRODUCTION. Resistance Welding is a thermo-electric welding process where the weld is made by a combination of pressure and current. The process is a simple joining of metals by applying controlled pressure and passing current for a length of time through the metal area to be joined. There are several different forms of resistance welding (e ...
