What is the conductivity of tungsten electrodes and how does this affect the welding process?

The conductivity of tungsten electrodes is excellent and has a profound impact on the welding process. Tungsten electrodes have a lower resistivity, which means that current can pass more efficiently, making them an excellent conductive material. This characteristic plays a crucial role in the welding process, as it directly affects the stability of the arc. The stability of the arc is crucial for welding quality, as a stable arc can ensure the uniformity and strength of the weld, thereby ensuring the quality and reliability of the welded joint.

The excellent conductivity of tungsten electrodes also makes the welding process faster and more efficient. The current flows smoothly through the tungsten electrode, accelerating the welding speed and improving production efficiency. This is particularly important for industrial production, as it means that more welding work can be completed in a shorter time, thereby reducing production costs.

Not only that, good conductivity also helps to control the heat affected zone during the welding process. The uniform distribution of heat can reduce the heat affected zone, help maintain the original properties of the material, and reduce the risk of welding deformation and cracks. This is particularly important for situations that require high-precision welding, such as aerospace, precision machinery, and other fields. Due to the efficient passage of current through the electrode, the risk of electrode damage due to overheating is reduced, thereby extending the service life of the electrode and reducing the frequency and cost of electrode replacement.
