Resistance welder / List of 6 manufacturers
What is a Resistance welder?
A resistance welder is a machine that welds metal by superimposing the metals to be welded and sandwiching the parts to be welded with electrodes so that electricity can flow through the metal and at the same time passing electricity while applying pressure. When welding, Joule heat generated by the resistance of the metal to be welded when electricity is applied is used. There are inverter type, transistor type, capacitor type, etc. depending on how the current flows. In addition, depending on the method of energization, it can be divided into direct spot type, indirect spot type, series spot type, and twin spot type.
Application of Resistance welder
Resistance welders are used in automobile factories, home appliance factories, construction materials, and other factories that have welding in the production process. Since the welding speed is high and there are few consumable parts, it is easy to automate, and products that support automation are also on sale. When selecting a resistance welder, it consumes a lot of electricity, so it is necessary to consider the impact on other electrical equipment and costs such as electricity costs and equipment costs. As for the installation method, there are a method in which the electrode is fixed and the metal to be welded is moved, a method in which the electrode can be moved, and a method in which multiple points can be welded at the same time. need to do it.
