Why tungsten carbide welding rod is used for hard surfacing?

In the field of metal processing, hardfacing overlay welding is an important process to enhance the surface properties of workpieces, and tungsten carbide welding electrodes are highly favored in this process.

What makes tungsten carbide electrodes the preferred choice for hardfacing is, first and foremost, their high hardness. Tungsten carbide hardness is extremely high, Mohs hardness up to 8.5 - 9, can form a hard wear-resistant surface layer after surfacing, so that the workpiece resistance to abrasion, scuffing ability to greatly enhance the effective prolongation of service life, especially for mining machinery, building materials equipment and other long-term components in a high-friction environment.

Secondly, tungsten carbide electrodes have excellent high temperature resistance. In the high temperature environment, tungsten carbide can maintain stable chemical and physical properties, to prevent the surface of the workpiece due to high temperature oxidation, deformation and other problems, such as thermal power generation equipment, high temperature parts of the surfacing often use tungsten carbide electrodes. In addition, the coating after surfacing with tungsten carbide electrodes has good corrosion resistance. In the chemical industry, marine engineering and other fields, the workpiece is susceptible to corrosive media erosion, tungsten carbide formed cladding layer can resist a variety of acid and alkali corrosion, to protect the normal operation of equipment.

At the same time, tungsten carbide welding electrode has good welding process performance, relatively simple operation, and can be overlaid by common welding methods such as electric arc welding, reducing the construction difficulty and cost. With these excellent properties, JINXIN tungsten carbide welding rod occupy an important position in hardfacing, providing reliable surface reinforcement for all kinds of industrial production.
