Weld performed by depositing metal on the surface of materials or workpiece to obtain the required surface properties or dimensions. It is an important manufacturing method and a major maintenance method in the mechanical manufacturing industry. overlaying often plays a role in surface strengthening, improving wear resistance, impact resistance, corrosion resistance, oxidation resistance, cold and hot fatigue resistance, etc. It can significantly improve the service life of the workpiece, save manufacturing and maintenance costs, improve productivity and economic benefits, and can also reasonably use materials to obtain excellent comprehensive performance.
