1. The hot wire surfacing equipment mainly includes a welding power source, a hot wire power source, a wire feeding system, a TIG welding torch, a control system, etc.

2. Hot wire surfacing has the characteristics of high deposition rate and high deposition efficiency, which can significantly improve production efficiency. Since the welding wire enters the molten pool after being preheated, the welding heat input is reduced, and the dilution rate of the base metal is decreased, enabling the surfacing layer to better maintain the required performance.

3. The surfacing layer has good quality, a smooth and flat surface, beautiful forming, and fewer defects such as pores and cracks.

It can accurately control the composition and performance of the surfacing layer, and appropriate welding wires can be selected for surfacing according to different working conditions and material requirements.
