Applications
This electrode is suitable for multiple resistance welding setups, including:
Electronic metal parts and precision connectors
Sheet-metal lap welding for light industrial components
Terminals, frames, brackets, and small structural parts
Automated production lines requiring repeatable weld points
Welding of steel, stainless steel, and plated materials
Lap Welding Process
Lap welding joins overlapping metal sheets. Heat builds at the interface as current flows through the electrode.
Process Benefits:
Simple fixture design
Uniform weld nugget formation
Suitable for thin and mid-thickness metal sheets
Electrode Requirements:
Tungsten-copper inlaid electrodes maintain firmness under pressure and provide steady electrical resistance, making them suitable for continuous production environments.

Frequently Asked Questions (FAQ)
1. What advantage does a tungsten inlay provide?
It withstands high pressure and heat, keeping the contact surface stable during repeated welding.
2. How long can the electrode be used?
Service life depends on current, pressure, and sheet material, but tungsten inserts generally last longer than copper-only structures.
3. Can you adjust the shape of the inlay?
Yes. We can modify the inlay depth, width, or geometry based on your drawings.
4. What materials can this electrode weld?
It works with carbon steel, stainless steel, coated steel, and common industrial alloys.
5. How should the electrode be maintained?
Keep the surface clean, control welding parameters, and ensure proper cooling during operation.
