摘要:
为研究碳钢和铝合金2种材料焊接烟尘的扩散规律和对人的危害特性，选取典型的碳钢和铝合金焊接烟尘，利用实验研究和数值模拟的方法，对2种烟尘的粒径分布、分散度、压缩度、微观形貌等特性和扩散规律进行对比分析，研究其危害特性和扩散规律的差异。研究结果表明：碳钢烟尘颗粒中PM2.5和PM10的占比均高于铝合金焊接烟尘，碳钢烟尘颗粒在空气中更不易沉降，扩散速率快、车间内积聚浓度高，对人体的危害性更大。研究结果可为电焊烟尘的有效收集控制提供理论支撑。
Abstract:
In order to study the diffusion laws and harmful characteristics of welding fume of carbon steel and aluminum alloy,the typical welding fume of carbon steel and aluminum alloy were selected,then the experimental research and numerical simulation methods were used to compare and analyze the characteristics and diffusion laws of the two kinds of welding fume,such as the particle size distribution,dispersion degree,compression degree and microscopic morphology,and the differences in their hazard characteristics and diffusion laws were studied.The results show that both the proportions of PM2.5 and PM10 in the fume particles of carbon steel are higher than those of aluminum alloy welding fume,and the fume particles of carbon steel are less likely to settle in the air,with fast diffusion rate,high accumulation concentration in the workshop,and greater harm to the human body.The research results can provide theoretical support for the effective collection and control of welding fume.
