Caps Electrode For Resistance Welding
OVERVIEW
Caps Electrode For Resistance Welding is especially suitable for the modern industrial welding needs of automation, high precision, and high load. Especially, the spherical geometric characteristics can evenly distribute the welding pressure, making it particularly suitable for welding plates of unequal thickness or materials with easily damaged surfaces (such as aluminum alloys and coated steel plates), reducing workpiece deformation. In high-frequency welding, heat dissipation is faster, and the service life can be extended by 30% to 50% compared to planar electrodes.
FEATURES
Excellent electrical and thermal conductivity
The electrical conductivity of 20-50 MS/m is higher than stainless steel (≈1.4 MS/m), ensuring efficient current transmission and reducing energy loss during welding. The thermal conductivity of 300-400 W/(m・K) helps dissipate heat, preventing overheating and softening of the electrode.
Good strength and strong anti-adhesion ability
The room temperature hardness of 100-120 HB makes it suitable for stable welding in high temperatures. Copper has low affinity with aluminum and steel, reducing adhesion between the electrode and workpiece during welding and improving production efficiency.
Excellent processing technology
It's easy to cut, grind, and electrospark machine, making complex-shaped welding caps (like spherical, flat, or boss) to suit different workpieces.
Wear-resistant and long-lasting
The electrode has a low wear rate during welding, good dimensional stability, and maintains consistent welding performance, reducing replacement costs.

APPLICATION
Caps Electrode is a type of spherical electrode, which is very suitable for various fields such as aerospace, shipbuilding, the automobile industry, electronic devices, metal processing, and the construction industry. It can reduce the adhesion between the electrode and the workpiece and achieve high-quality welding.
1. Automobile manufacturing industry
Body welding: used for spot welding of body structures (such as doors, side panels, chassis, etc.), and the welded materials are mainly galvanized steel plates and high-strength steel.
Battery system: welding of new energy vehicle battery pack shells (aluminum alloys) and copper/aluminum foil.
2. Electronics and home appliance industry
Consumer electronics: precision welding of internal metal parts of mobile phones and laptops. The electrode head has high dimensional accuracy (such as small diameter welding caps of φ2-5mm).
Home appliances: welding of refrigerator and air-conditioning compressor components, and spot welding of stainless steel liner.
3. Aerospace field
Spot welding of titanium alloy and high-temperature alloy structural parts requires the electrode to maintain strength at high temperatures (such as aluminum oxide copper, softening temperature> 900℃).
4. Hardware and metal processing industry
Automated welding of stainless steel products such as kitchenware, shelves, and metal mesh, or butt welding of steel wires and steel bars.
NOTES ON MAINTENANCE
In order to extend the service life, technicians need to regularly perform grinding and surface cleaning on Caps Electrode For Resistance Welding to maintain the geometric accuracy of the end face. Anti-rust oil can be applied during long-term storage, or plated electrodes (such as nickel plating) can be used to improve corrosion resistance. If necessary, the electrode can be cooled to prevent high temperatures from causing the alloy to soften.
PROCESS
①Select suitable raw materials according to application needs, such as chromium copper, aluminum oxide copper, etc.
②Ensure uniform composition through vacuum melting or medium frequency induction melting, copper and aluminum melting (Al content 0.3%~0.7%).
③Achieve uniform deformation through multiple forging or extrusion.
④Annealing treatment to eliminate thermal processing stress and adjust the balance between hardness and conductivity.
⑤Precision turning and polishing, processing into flat or spherical surfaces according to welding requirements.
⑥Performance testing and quality control, such as physical performance testing, dimensional accuracy inspection, and welding performance verification.
