What is a welding transformer?

2025-11-12
A resistance welding transformer is a transformer specifically designed for resistance welding. It reduces the voltage of the mains electricity but generates a high current of thousands to tens of thousands of amperes. This uses the resistance between the workpieces to generate heat, melting the metals and joining them. This transformer is highly efficient and fast, and is primarily used in spot/projection welders, seam welders, and butt welders. It is also suitable for difficult-to-weld mater...

What is a Resistance Welder?

2025-11-12
Resistance welder, is a device that weld metal materials together using the principle of resistance heating. The working principle Is By applying pressure and passing an electric current through the contact points of the workpieces, the heat generated by the workpieces' resistance melts the metal, which then cools to form a strong spot or seam welding. This welding method is widely used in the automotive, home appliance, sheet metal fabrication, electronic component, metal furniture and c...

The main types of the Resistance welders?

2025-11-12
1)Resistance Spot Welding: It is a process to join two or more metal sheets by applying pressure and passing an electric current through them. The resulting resistance heating melts the metal at a concentrated spot, creating a fused bond upon cooling. This efficient, cost-effective, and automatable process is widely used in the automotive industry for joining thin sheets. 2)Projection Welding: It is a type of resistance welding that uses pre-designed projections on the workpiece to concen...
