I have to write a report on Resistance Welding, and I have no idea what it is. I was wondering if you could give me a little discription of what it is, and maybe name some of the tools that are involved in Resistance Welding. If you could answer these questions for me I would be very thankful.

Resistance welding uses heat and force to create a bond between two base metals. There are several different forms of resistance welding such as spot, seam, and projection welding. The differences between the three involve the types and shapes of weld electrodes used and the actual process involved. Weld electrodes are used to actually conduct the heat to the base metals as they are forged together. These electrodes are usually made of copper because of its conductivity and low resistance. Generally, water is used to cool the electrodes during the process. Water flows inside the cavity of the electrode, thus removing excess heat. Many different types of welding machines can be built to fit many different types of applications. Below is a list of links that may provide more information on resistance welding and the applications involved as well as links to other types of welding.

I hope this information has helped.
