摘要

采用ERNiCrMo-3 AMS Inconel625焊丝，在15CrMoG膜式水冷壁表面进行熔化极气体保护焊（GMAW）堆焊成形工艺试验，研究焊接电流和焊枪摆动频率对堆焊层表面成形的影响，分析了堆焊层金属组织演变规律，并测试其显微硬度。结果表明：焊接电流主要影响堆焊层宽度及表面氧化程度，焊枪摆动频率主要影响堆焊层表面鱼鳞纹细腻程度，当焊接电流为180 A，焊枪摆动频率为10 Hz时，可获得成形良好的堆焊层；堆焊层金属组织从堆焊层底部至顶部的演变规律为：平面晶→柱状胞晶→树枝状晶→等轴晶，堆焊层顶部由于散热方向由垂直于熔合线方向变为平行于熔合线方向，出现部分横向组织；堆焊层金属的显微硬度由基体沿垂直于熔合线方向呈上升趋势，堆焊层表面的显微硬度分布均匀，平均硬度为270.6 HV。

Abstract

Gas metal arc welding (GMAW) surfacing test was carried out on the 15CrMoG membrane water-wall by using ErNiCrMo-3 AMS alloy Inconel625 wire. The influence of welding current and welding gun swing frequency on the surface forming of surfacing layer was studied. The evolution of microstructure of surfacing layer was analyzed and its microhardness was tested. The results show that the welding current mainly affects the width and surface oxidation degree of the surfacing layer, and the swing frequency of the welding gun mainly affects the fineness degree of the fish-scale grain on the surface of surfacing layer, when the welding current is 180 A and the swing frequency of the welding gun is 10 Hz, a well-formed surfacing layer can be obtained. The evolution of microstructure of surfacing layer from bottom to top is as follows: planar crystal → columnar cellular crystal → dendritic crystal → equiaxed crystal. As the heat dissipation direction changes from perpendicular to the fusion line to parallel to the fusion line, some transverse microstructure appears on the top of surfacing layer. The microhardness of the surfacing layer increases from the substrate along the direction perpendicular to the fusion line, and the microhardness of the surface is evenly distributed, and the average microhardness is 270.6 HV.
