60Si_2Mn、50CrVA类弹簧钢多用于制造重负荷、高疲劳极限、高弹性的重要弹簧或弹性机件,由于含碳量高并含有一定的合金元素,可焊性较差,施焊时必须按其特性,采取相应的工艺。下面就这两类弹簧用手工电弧焊接的情况作一介绍。 60Si_2Mn, 50CrVA type spring steel used to create heavy load, high fatigue limit, high elasticity of the important spring or elastic parts, due to high carbon content and contains a certain amount of alloying elements, poor weldability, welding must be according to their Characteristics, to take the appropriate technology. The following two types of springs with manual arc welding for an introduction.
