摘　　要：通过对大直径20MnMo锻件管板埋弧带极堆焊309LMo的焊接及生产应用的研究,合理选择过渡层焊接材料及堆焊各层的工艺规范参数,减小堆焊层合金元素稀释率,控制铁素体含量,保证了堆焊质量,解决了管板堆焊变形的问题,成功用于产品制造。Based on the welding test and production applications on the belt built up welding 309LMo to the 20MnMo forging pipe steel, it is expounded that key to guarantee the welding quality ,reduce the al by element dilution ratio of the built up welding and control ferrite is the reasonable choice of the transitional layer welding material and process parameters. Take prevention measure to control welding distortion, succeed in the manufacture of methanol synthetic towers.
