摘　　要：为优化焊接车间的通风布置,降低焊接车间内焊烟浓度,减少焊接烟尘对施工人员身体健康造成的危害,采用数值分析方法对焊接车间内部焊接烟尘的分布情况进行模拟,并提出焊接车间的通风布置优化建议。结果表明:采用自然通风与风机机械排风相结合的方式对降低焊接车间内焊接烟尘浓度具有较好的效果。研究成果可为船厂焊接车间的通风设计提供一定参考。In order to optimize the ventilation layout of the welding workshop,reduce the concentration of welding fumes in the welding workshop,and reduce the harm caused by welding fumes to the health of construction workers,the numerical analysis method is used to simulate the distribution of welding fumes in the welding workshop,and the optimization suggestions for the ventilation layout of the welding workshop are put forward.
