Stainless steel welded air pipe in large automotive welding workshop can mainly play the following roles:

1. Ventilation: timely discharge of harmful gases, smoke and dust generated in the welding process, keep the air in the workshop fresh, improve the working environment, and protect the health of workers.

2. Heat dissipation: help to dissipate the heat generated by welding equipment and workpieces, maintain the appropriate temperature, and avoid equipment overheating affecting performance and life.

3. Maintain air quality: effectively filter out impurities and pollutants in the air, improve air quality, and reduce irritation and damage to workers' respiratory tract.

4. Balanced air pressure: Ensure stable air pressure in the workshop to avoid adverse effects on production caused by local abnormal air pressure.

5. Fire safety: Good ventilation can reduce the risk of fire and also help to discharge smoke in the event of a fire.

6. Process guarantee: Stable air flow can provide suitable environmental conditions for welding process, improve welding quality and stability.

For example, through ventilation, the acrid smoke generated by welding can be quickly discharged, so that workers can work in a relatively comfortable environment; The heat dissipation function can prevent the failure of welding equipment due to high temperature. For example, when there is a local fire in the workshop, the stainless steel welded air duct can quickly direct the smoke to the exhaust outlet and buy time for personnel evacuation.
