Spot welders use a process called resistance welding. This process uses heat from an electrical current, and by applying pressure. Typically this process is used weld two or more pieces of sheet metal together. One of the major benefits to spot welding, is the ability to send a large amount of energy to a small spot in a short time. This lets the particular weld reach high temperatures without causing the heat to travel across the whole piece of metal. The resistance between electrodes and the magnitude of the duration of the current determine the amount of heat delivered.
Arc welders also use electricity to create heat, and this heat is used to melt the metal and when it cools, the metal binds to each other. There is an arc between the welding stick and the base material at the point of contact which causes that reaction. The weld area is typically protected by some sort of shielding gas, vapor, or slag. Arc welding was developed in the 19th century and was a pivotal part of ship building during the Second World War.
Seam welders are used to make gaseous or liquid joints for applications in sheet metal. This welder also uses a roller instead of using a stick. This method is mainly used on a variety of metals in pipes including its use on auto mufflers. HGR has all of these types of used welders in stock and ready to go.
