AI Technical Summary

Technical Problem

Welding fumes generated during the welding process pollute the air and pose a threat to human health, and existing technologies are unable to effectively control them.

Method used

Design an air curtain welding torch nozzle with an external fume extraction mechanism and an internal fume channel and fume inlet mechanism. Combined with a linkage height and tilt adjustment mechanism and a turbulence slag removal mechanism, it can effectively extract and remove welding fumes.

Benefits of technology

To reduce the amount of welding fumes drifting in the air, protect the environment and worker health, adapt to different welding morphologies, reduce damage to dust collectors caused by welding slag, and improve the safety and cleanliness of welding operations.
