Product Description
1. Introduction to resistance welding
Resistance welding refers to the method of using the resistance heat generated by current passing through the weldment and the
contact point as a heat source to locally heat the weldment and pressurize the welding at the same time.
Resistance welding is a method that uses the resistance heating effect generated by the current flowing through the contact
surface and adjacent areas of the workpiece to heat it to a molten or plastic state to form a metal bond.
There are four main resistance welding methods, namely spot welding, seam welding, projection welding, and butt welding. Among
these four methods, resistance welding electrodes are required. Our company specializes in the production of resistance welding electrodes, from powder to tungsten and molybdenum products, tungsten-copper combination to precision-machined products, all are produced by our company. With many years of experience in the production and supply of welding electrodes, we have rich experience in how to improve product performance and life.
1). Spot welding: It is a high-speed and economical welding method, suitable for spot welding of carbon steel plates and stainless steel plates, high-carbon steel saw blades, iron wire products, wire terminals, auto parts, stainless steel products, low-voltage electrical appliances, and hardware Lighting, kitchen utensils, small household appliances, small hardware and other industries.
The materials used for spot welding include chromium zirconium copper, alumina copper and beryllium copper, etc. Our company has precision processing capabilities and can process them according to the drawings.
In addition, the copper-inlaid tungsten and copper-inlaid molybdenum electrodes produced by our company have remarkable welding performance and solder joints when welding copper wires, copper braided wires, copper sheets, copper tabs, carbon brush holders, gold wires, copper wires, aluminum foil, etc. Small, high consistency, long welding times and long life.
2). Seam welding: Seam welding is an extension of spot welding. It presses the weldment through a roller electrode and
continuously rotates to send power to form a continuous weld. Our company produces seam welding electrodes, and the materials include molybdenum alloy and tungsten alloy. In addition, our company also produces parallel sealing and welding electrode wheels.
These electrodes are also called capping electrodes and tungsten copper sealing and welding electrodes. They are mainly used in equipment for welding packaging devices, optical devices, sensor devices, and micro-electromechanical system devices.
3). Projection welding: Projection welding is also a form of spot welding. It uses the original profile, chamfer, and
prefabricated bumps on the part to weld it to another larger part. In addition to projection welding of plates, projection welding also includes projection welding of nuts and screws, cross projection welding of wires, projection welding of pipes, and T-shaped projection welding of plates.
In terms of nut projection welding, tungsten copper nut electrodes are usually required. Our company can provide a variety of end faces such as pure tungsten, pure molybdenum, tungsten copper, etc. The base material is chromium zirconium copper. Made by back casting, the material life is much longer than that of the chromium zirconium copper nut electrode cover. Our company provides nut electrodes of different specifications. We can provide directly back-cast tungsten-copper nut electrodes through drawings, or we can provide tungsten-molybdenum wafers or tungsten-copper wafers for customers to use for brazing.

2. Definition, performance and characteristics of resistance welding electrodes
The resistance welding electrode is a component of the resistance welding machine that directly contacts the weldment and transmits current to the weldment. It has an important impact on the welding quality and efficiency.
Resistance welding electrodes are usually made of metal materials with good electrical conductivity, such as copper, chromium zirconium copper, and tungsten copper. Its shape and size will be designed and manufactured according to the specific welding process and weldment requirements.
During the resistance welding process, the electrode generates resistance heat through contact with the surface of the weldment, causing the weldment to be locally heated to a molten or plastic state, thereby achieving welding.

During the resistance welding process, the electrode generates resistance heat through contact with the surface of the weldment, causing the weldment to be locally heated to a molten or plastic state, thereby achieving welding.
In order to ensure welding quality, the electrode needs to have the following characteristics:
1). Good electrical conductivity: ensure that current can pass through the electrode evenly to produce a uniform heating effect.
2). Appropriate hardness and wear resistance: It can withstand the pressure and friction during the welding process and extend the service life of the electrode.
3). High temperature resistance: maintain good performance at high temperatures and avoid deformation or melting.
4). Easy maintenance and replacement: It facilitates cleaning and trimming of electrodes to ensure the stability of welding
quality.
In addition, the surface quality of the electrode will also affect the welding quality. The electrode surface should be smooth and flat without dirt, oxide layer or other impurities to ensure good contact with the weldment.
