焊接作业过程中产生大量的电焊尘，同时产生辐射热，本文从降低工人作业位置电焊尘浓度和提供工人热舒适环境两个方面探讨了排风和送风系统设计．为改善焊接作业环境劳动卫生状况提供了一个良好方法．
In the process of welding, a large amount of welding dust is generated and radiant heat is generated at the same time. This paper discusses the design of exhaust and blowing system from two aspects: reducing the concentration of welding dust in workers’ working positions and providing the thermal comfort environment for workers. It provides a good way to improve the labor hygiene in the welding operation environment.
