Resistance welding is a process that joins two pieces of metal together by heating them to a welding temperature with an electrical current and then pressing them together. The resistance to the current passing through the metal creates the heat.
There are many different types of resistance welders, but the most common are the spot welder and the seam welder.
Spot welders are used to weld two pieces of metal together by heating them to a welding temperature and then pressing them together.
The resistance to the current passing through the metal creates the heat. The spot welder has two electrodes that are used to create the weld.
The electrodes are placed on opposite sides of the metal and then the current is passed through the metal. The electrodes create a spot on the metal where the current is passing through and this is where the weld is formed.
The weld is then cooled and it forms a bond between the two pieces of metal.
Seam welders are used to weld two pieces of metal together by heating them to a welding temperature and then pressing them together.
The resistance to the current passing through the metal creates the heat. The seam welder has two electrodes that are used to create the weld.
The electrodes are placed on opposite sides of the metal and then the current is passed through the metal. The electrodes create a seam on the metal where the current is passing through and this is where the weld is formed.
The weld is then cooled and it forms a bond between the two pieces of metal.
