摘　　要：为使HSMZ-80混合型轴向摩擦焊机具有径向摩擦焊接功能,对焊机机械系统、液压系统和电气控制系统进行改造:在焊机主轴增设防扭机构;液压系统配置比例伺服阀;基于PLC+PC机的摩擦焊机控制系统,径向摩擦焊接过程在时间+位移控制的基础上采用定值扭矩控制,成功解决了2级摩擦焊接阶段扭矩超调引起电机堵转的问题。在改造的摩擦焊机上成功实现了钢管径向摩擦搭接焊。通过金相组织、力学性能等检测分析,焊缝组织良好,无气孔、夹渣、未熔合等缺陷,焊接接头具有良好的综合力学性能。To make HSMZ-80 friction welding machine have the function of radial friction welding,mechanical system,hydraulic system and electrical control system are transformed.Anti-twist unit is added to spindle system;Hydraulic system is configured with proportional servo valve.Based on PLC+PC control system for radial friction welding,the problem of motor locked-rotor is solved by using setting torque control mode which is based on time +displacement control.Steel pipe radial friction lap welding is achieved successfully on the transformation.Through the analysis of microstructure and mechanical properties,the weld has good microstructure, and there is no porosity, slag, incomplete fusion and other defects.The weld has good mechanical properties.
