Products Description
Tungsten Copper welding Wheels are made of tungsten and copper alloy which has the advantages of tungsten and copper, with high temperature resistance, arc erosion resistance, high strength, high specific gravity, good electrical and thermal conductivity, easy cutting and processing, and sweat cooling properties.
Due to the high hardness, high melting point, and adhesion resistance of tungsten, they are often used to make convex welding and butt welding electrodes with certain wear resistance and high temperature resistance.
When tungsten copper welding wheels are used for molds made of tungsten steel and high-temperature resistant superhard alloys that require electrical corrosion, ordinary electrodes have high losses and slow speeds. The high electrical corrosion rate, low loss rate, precise electrode shape, and excellent machining performance of tungsten copper welding wheels can greatly improve the accuracy of the machined parts.
During the operation of tungsten copper welding wheels, the contact material will experience a temperature increase of several thousand degrees Celsius in just a few seconds. The high anti erosion performance, high toughness, and good electrical and thermal conductivity of tungsten copper provide necessary conditions for the stable operation of discharge tubes.
features
Increased Hardness and Melting Point: During welding, the tungsten-copper welding wheel maintains its structural integrity because of the high melting point it possesses. It's wear-resistant materials with high hardness which ensures extended service life.
Performing Thermal and Electrical Conductivity: With copper being added, electrical conductivity improves allowing current to be supplied efficiently during welding. Also, high thermal conductivity enables rapid heat dissipation, preventing excessive rise in temperature.
Stable Size: Tungsten-copper alloy maintains a stable size even when subjected to elevated temperatures due thermal expansion. These characteristics in the copper alloy aid in precise and consistent welding.
Resistance to Corrosive Environment: The material demonstrates enhanced resistance against corrosion which is ideal for use over an extended period irrespective of the conditions.
applications
Seam Welding
Tungsten-copper welding wheels work well for metal sheet welding. They often weld things like tin cans. In seam welding, two wheel electrodes hold the workpieces. The wheels act as electrodes. Electric current makes heat. The heat melts the metal. This makes a continuous weld.
Resistance Welding
These wheels work for spot welding. They also work for projection welding. They resist wear very well. They can handle high heat. They work steadily under strong current. They stay strong under high pressure.
Aerospace & Car Making
These wheels weld strong metals. They weld stainless steel. They weld aluminum. They make strong joints. The joints stay reliable. This is important for planes and cars.
Electronics Industry
These wheels make electronic parts. They make heat sinks. They make electrodes. They work well because they conduct heat. They also conduct electricity.
