摘 要: 使用模糊评价法对药芯焊丝进行了生命周期评价,评价内容包括药芯焊丝的钢带和辅料的生产、运输,焊丝的制备以及药芯焊丝在焊接过程中产生的有害烟尘对焊工健康的影响,对药芯焊丝的环境影响进行了全面、量化的评价,由评价结果可以看出,药芯焊丝的外皮钢带在生产以及焊接过程中对环境造成的负荷最大,锰铁、硅铁的加入也产成了较为严重的环境负荷。 A life cycle assessment on the flux-cored wire was done in this paper and a general and quantified result of environment impact of flux-cored wire was obtained. Method of fuzzy assessment was used in the assessment to get the results of impact satisfaction. The conclusion is that the steel strip makes the heaviest environment burden and ferrosilicon takes the second place on the basis of comparing the impact satisfactions of steel strips and materials.
