摘要
液压元器件中大多采用碳钢材料进行制造,不仅重量大而且耐蚀性较差,影响了主机性能和寿命。采用6061-T6铝合金替代原有碳钢材料制造液压元器件,不仅实现了主机重量轻而且耐蚀性指标有大幅度提升。然而这种铝合金焊接部位容易出现软化现象,该文探究了不同焊丝对6061-T6铝合金TIG焊焊接接头性能的影响。
Most of the hydraulic components are made of carbon steel, which not only has a large weight and poor corrosion resistance, but also has a great influence on the performance and life of the machine. The use of 6061-T6 aluminum alloy to replace the original carbon steel material manufacturing hydraulic components, not only to achieve a light weight but also to increase the corrosion resistance. However,this kind of aluminum alloy welding parts prone to soften phenomenon, this paper explores the effect of different welding wire on the 6061-T6 aluminum alloy TIG welding joint performance.
