AI Technical Summary

Technical Problem

During the welding process of steel structure plates, the waste gas generated during welding can easily enter the surrounding environment, causing environmental pollution.

Method used

The system employs a negative pressure box and a connected circular box structure. Steel structural plates are fixed by support suction cups, and negative pressure is generated by an air pump for fixation. Combined with the rotation of the connected circular box, welding exhaust gas is treated and the plates are stably fixed, thereby enhancing welding stability.

Benefits of technology

It effectively fixes steel structure plates, reduces welding exhaust pollution, improves welding cooling rate and stability, and ensures the environmental friendliness and efficiency of the welding process.
