Resistance Spot Welding - How It Works

Aresistant spot welder is designed to  deliver a low-voltage high-current  electrical pulse the weld electrodes of  made of copper because copper has a low  resistance to current flow which allows  it to conduct electricity with ease  steel is a very poor conductor of  electricity and it will resist the weld  current as it flows from the spot welder.

The friction created by the current  forcing its way through the metal heats  the weld area to over  degrees  Fahrenheit the squeeze pressure from the  weld electrodes now compresses the  molten area and fuses the two metal  surfaces into one solid nugget by  maintaining the squeezed pressure for a  short time after the weld current is  shut off which is known as whole time.

The molecules in the welded material  remain compressed as the weld cools  this additional pressure results in a  much stronger weld electricity in your  shop how it works and why you need to  understand how it affects the  performance of your welders and other  equipment single-phase....
