What is weld overlay?

Welding, as an economical and rapid process for material surface modification, is increasingly widely used in the manufacturing and repair of parts in various industrial sectors. In order to effectively utilize the role of the weld overlay layer, it is hoped that the weld overlay method adopted will have smaller base material dilution, higher deposition speed, and excellent weld overlay performance, that is, high-quality, efficient, and low dilution rate weld overlay technology.

Welding is widely used in various industries such as manufacturing and maintenance, ship power, machinery industry, petroleum and petrochemical industry, etc.

Welding overlay is a surface welding process carried out to increase the size and dimensions of iron processed welded parts, restore welded parts, or deposit metal with special surface properties.
