Graphite Welding Rod

Graphite Welding Rod for Sale

Generally, the graphite welding rod is in a rod shape. Its advantages are quite outstanding.

Excellent high temperature resistance

It can be stable in high temperature environment. In the welding process, it is not easy to melt deformation, to ensure the structural integrity of the welding parts.

Good electrical conductivity

It can effectively conduct current in the welding circuit, ensure the stable combustion of welding arc. So as to achieve high quality welding connection.

Relatively stable chemical properties

It is able to withstand a certain degree of chemical erosion. And reduce the possibility of adverse reactions with the surrounding medium in complex environments.

Certain lubricity

This helps to flow and fill the solder in the welding process, so that the weld is more uniform and dense.

Moderate mechanical strength

It can withstand a certain external impact, to ensure the solidity of welded joints.

Low coefficient of thermal expansion

It can effectively reduce the internal stress caused by thermal expansion and contraction during the cooling process after welding. And reduce the risk of welding cracks. This is particularly important for some welding structures that require high precision and stability.

Types of graphite welding rods

Jinsun carbon graphite welding rod mainly has the following types.

Classified by graphite content:

High graphite content electrode

Graphite content of 80% and above, this electrode has better conductivity and high temperature resistance. It is suitable for metal connections with high conductivity requirements, such as conductive parts in electrical equipment welding repair.

Medium graphite content electrode

The graphite content is between 60% and 80%, the comprehensive performance is more balanced. It can ensure a certain electrical conductivity and high temperature resistance, but also has good operability. You can often use it in the welding of general industrial equipment. Such as the repair and connection of ordinary mechanical parts.

According to the classification of added materials:

Metal added graphite welding rod

Adding such as copper, silver and other metal powder, on the basis of ensuring the performance of graphite. These improve the strength and toughness of the electrode, suitable for welding parts under greater mechanical stress. Such as mining machinery, construction machinery key components welding.

Ceramic addition type graphite welding rod

The addition of ceramic particles, enhance the wear resistance and corrosion resistance of the electrode. You can use it in the harsh wear and corrosion environment of the parts welding. Such as the mixing paddle in chemical equipment, pipeline valve repair.

Classification by diameter:

Fine diameter graphite welding rod

The diameter is usually between 2mm-4mm, easy to operate, suitable for fine welding and thin-walled parts welding. It can accurately control the welding heat input, reduce the heat impact on the base metal.

Thick diameter graphite welding rod

Diameter of 6mm-10mm and above, high deposition efficiency. It is suitable for large thick wall parts welding, can quickly fill the weld, improve welding efficiency.

Uses of graphite welding rods

Graphite welding rod is widely used.

In the field of machining and manufacturing

You can use it to repair turning tools, milling cutters and other tools and molds. It can extend their service life, ensure accuracy and surface quality.

In the field of electric power

You can use it to repair transformers, motor conductive parts and grounding devices to ensure stable and reliable power transmission.

Chemical and metallurgical industries

You can use it to repair reactor, pipeline, furnace parts, etc.. It can reduce equipment replacement costs, maintain production.

In the field of automotive and Marine repair

You can use it to repair engine cast iron components and Marine components to ensure performance and safe navigation.
