摘　　要：随着制造业的飞速发展,焊接技术成为不可或缺的材料加工方式之一。钢结构焊接过程中母材以及焊丝中所产生的烟尘含有毒性巨大的六价态铬[Cr(Ⅵ)]元素,会严重危害作业人员的身体健康,并引发各类呼吸道疾病,因此开展降低烟尘中Cr(Ⅵ)含量的研究不仅是保证焊接工人健康的重要途径,也是发展绿色焊材的关键。综述了焊接烟尘中Cr(Ⅵ)的形成机理、危害及治理措施,分析了实际生产中焊接烟尘治理Cr(Ⅵ)存在的问题,指出了钢结构母材和焊材所产生的焊接烟尘的研究难点及今后的发展方向。With the rapid development of manufacturing industry,welding technology has become one of the indispensable material processing methods.The fume generated from the base material and welding wire during the welding process of steel structures contains the toxic element of hexavalent chromium[Cr(Ⅵ)],which can seriously endanger the health of workers and cause various respiratory diseases.Therefore to carry out the work of reducing the Cr(Ⅵ)content in the fume is not only an important way to ensure the health of welders,but also the key to the development of green welding materials.This paper reviews the formation mechanism,hazards and management measures of Cr(Ⅵ)in welding fume,and analyzes the problems of Cr(Ⅵ)in welding fume management in actual production.Points out the research difficulties and future de‐velopment direction of welding fume generated by steel structure base material and welding material.
