There are many differences between resistance and arc welding. The two main differences are the type of current used and the electrode type.
Resistance welding uses direct current (DC), while arc welding uses alternating current (AC). This means that the arc is constantly changing directions, which makes it easier to control. electrodes.
The other difference is in the electrode type. Arc welding electrodes are made from a variety of materials, including steel, stainless steel, aluminum, and even copper. They come in different shapes and sizes, depending on the application. Resistance welding electrodes are made from graphite or metal, and they are much smaller than arc welding electrodes.
