本文分析总结了CO_2气体保护焊用的小直径焊丝(d≤1.0mm)的焊接工艺性能及机械性能和表面质量的密切关系。认为弹性模数能满足使用要求,屈服强度、硬度和表面粗糙度应作为焊丝质量控制指标。
This paper summarizes the close relationship between welding performance and mechanical properties and surface quality of CO_2 gas shielded welding small diameter wire (d≤1.0mm). That the elastic modulus to meet the requirements, yield strength, hardness and surface roughness should be used as wire quality control indicators.
