Welding of copper with tungsten electrode

Are you interested in welding copper using tungsten electrodes from the supplier company AvecGlob? Here you will find interesting information on this topic /

Process Features

Copper and its alloys are characterized by low thermal and electrical conductivity, so conventional welding techniques are not applicable here. Given the high mechanical strength of tungsten electrodes, they can be effectively used for welding copper by the method of resistance welding.

In the process of resistance welding, the connected parts are pressed by an external source and heated by an electric current until parts of the molten material are formed in separate points between them. This operation requires high currents and large clamping forces.

During the welding of thick sheets, the forces between the electrode and the parts to be joined can reach 450 MPa. This is a serious problem for welding electrodes that must withstand these loads. Such forces can withstand electrodes made, for example, from tungsten.

Supplier — AvekGlob Company — offers tungsten electrodes at a reasonable price from the manufacturer, which can be used for welding copper by resistance. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Types of tungsten electrodes for contact welding

Welding electrodes of tungsten have a relatively high level of electrical conductivity, and also have excellent stability at high temperatures. Therefore, they have a significantly longer service life than conventional materials, such as copper and copper alloys.

Especially effective are welding electrodes made of tungsten for welding materials with increased electrical conductivity. They are used in the following types of welding technologies:

spot welding;

roller welding;

projection (contour) welding.

Urgency of application

Tungsten electrodes are used for brazing copper and copper alloys, with high-speed spot welding of copper wire harnesses, which is used in engines, cars and anywhere complex or simple assemblies. Other applications include line commutators for batteries, as well as electrical components for the production of lines of automatic and electrical switches. In addition to using copper wires and terminals, tungsten electrodes are used in the manufacture of lithium-ion batteries and nickel hydrogen batteries, as well as in the welding of battery baths.

Supplier — AvekGlob Company — offers to purchase tungsten non-consumable electrodes of various diameters and shapes suitable for welding copper. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
