AI Technical Summary
Existing welding equipment generates toxic gases during the welding process, polluting the air and endangering health. At the same time, it is not convenient to observe the welding process and correct deviations in a timely manner.
A device comprising a welding torch, welding rods, and a transparent protective cover was designed. The protective cover is equipped with a gas purification mechanism and a scraper. The transparent material facilitates observation of the welding process. The scraper removes welding slag, and the purification mechanism purifies toxic gases.
It achieves the purification of toxic gases and the removal of welding slag during the welding process, protecting the health of workers, and facilitating the observation of welding results and timely correction of deviations.
