一、前言振动电弧堆焊,是修复磨损零件的先进方法之一。与一般电弧焊方法比较,有如下特点:1.采用小功率、低电压电流焊接,并采用冷却液体,对零件的热影响小。2.用振动焊丝堆焊,可以保证堆焊过程稳定,堆焊层薄而均匀,并能提高堆焊层的机械性能。3.堆焊过程是自动进行,热功率小并有冷却。由于加热与冷却均匀,因而零件没有或有极小的变形。 I. Introduction Vibrating arc welding is one of the advanced methods for repairing worn parts. Compared with the general arc welding method, has the following characteristics: 1. The use of low-power, low voltage current welding, and the use of cooling liquid, thermal effects on the parts small. 2. Vibrating wire welding, can ensure the stability of the surfacing process, surfacing thin and uniform, and can improve the mechanical properties of surfacing layer. 3. Surfacing process is automatic, small thermal power and cooling. Due to uniform heating and cooling, there is no or minimal deformation of the part.
