Basic Configuration of Resistance Welder and Role of Each Part
Resistance welder sandwiches an object to be welded by the welding electrodes,
andapplies electric current while applying a pressure.
- Welding Power Supply: It controls the magnitude, time and waveform of electric current
- Welding Transformer: It converts the electric current from the power supply to a larger current
- Welding Head: It controls the pressure to be applied
- Welding Electrode: It contacts the object to be welded to apply pressure and electric current
- In addition to the above, we have various monitors which measure electric current or applied pressure.
Resistance Welding Model, Temperature Distribution at the Welding
Welding Power Supply: Control Method
An appropriate welding power supply must be selected based on the material or shape of the object to be welded and the required welding quality.There are three different types in our welding power supplies based on the type of control of the welding current, and each type is selected in a way to best demonstrate its characteristic in welding.
Welding Head & Electrode
How the electrode contacts the object to be welded (how to apply the current) is determined by the shape or structure of the object. Furthermore, shape and material of the electrode and the applied pressure are also important factors in resistance welding.
