Applications

The double hole tungsten copper inlaid electrode is suited for a wide range of resistance welding tasks. It supports welding lines that require stable current flow and repeatable pressure control. Typical uses include:

• Sheet metal assembly in electrical equipment and household appliances。

• Connector, terminal, and sensor part welding。

• Bracket, hinge, and stamped part welding in hardware production。

• Lap welding of coated sheets, stainless steel sheets, carbon steel sheets, and copper alloy sheets。

• Automated production lines where consistent dimensional accuracy is required。

• Welding stations that run long duty cycles and need electrodes with reliable heat control。

• Its structure helps maintain stable welding quality even under frequent start-stop cycles in automated equipment.

Lap Welding Process

Lap welding joins two overlapped sheets by applying current and pressure through the electrode. Heat forms at the interface and creates a solid joint.

How It Works:

• Current flows through both sheets

• Resistance generates heat at the overlap surface

• Pressure ensures stable fusion

• Cooling forms the final joint

Process Advantages:

• Good joint quality for thin and medium-thickness metals

• Simple part alignment and clamping

• Adaptable to coated materials such as galvanized sheets

• Suitable for multi-point welding on the same workpiece

• Efficient for automated welding units and high-frequency cycles

Electrode Requirements:

• Tungsten copper electrodes retain shape under repeated pressure, keep the contact area stable, and help reduce thermal deformation. This supports constant welding sizes and lowers the need for frequent adjustments.
