Surfacing Welding Process

Surfacing welding process is an economical and rapid surface modification method that is increasingly applied in the manufacturing and repair of parts across various industrial sectors.

Principle:
The principle of the surfacing welding process is based on thermodynamics and metallography, aiming to deposit metal alloys through the melting and rapid solidification process, during which crystal growth occurs.
The process involves using a heat source to melt the welding material and deposit it onto the surface of the workpiece, thus altering the material's surface properties to achieve desired attributes such as wear resistance, heat resistance, and corrosion resistance.

Applications:
The surfacing welding process is widely used in various industries, such as aerospace, automotive manufacturing, petrochemical, construction, and energy. In aerospace, it is used to repair turbine rotors, turbine discs, and other aircraft components to extend their service life and improve performance. In automotive manufacturing, it is commonly applied for the repair and reinforcement of engine connecting rods, brake discs, and exhaust pipes. In the petrochemical industry, it is widely used for repairing oil pipelines and preventing chemical corrosion. Additionally, it is employed in the energy sector for repairing and improving power generation equipment and transmission lines.
