[0002] MAG cladding is a metal welding technology widely used in stainless steel manufacturing, construction and maintenance. This technology can repair and strengthen stainless steel workpieces and has high practical value. However, in the process of welding with MAG cladding equipment, even if the operator wears protective gear, the welding arc and smoke will still affect vision. Long-term exposure to arc and smoke may cause operators to lose vision and even cause other eye diseases.

In addition, the melting point and solidification speed of welding wire and weldment are different. During welding, it is necessary to wait for enough time for the metal to solidify to ensure the quality of the cladding layer, which limits production efficiency. Utility Model Content

After the welding is completed, the fan 308 can accelerate the solidification and cooling of the metal to facilitate the transfer of the finished product, thereby avoiding the impact of the welding arc and smoke on the operator's vision and saving the time required for production.
