摘　　要：利用自制微机控制的带极堆焊设备和烧结焊剂，开展了７５ｍｍ×０．４ｍｍ带极高速堆焊（ＨＳＷ）工艺的研究工作．探讨了影响焊道几何形状和稀释率的因素及其规律．通过实验研究得到了满足工艺要求的最佳工艺规范参数的范围，利用这些参数进行堆焊，并对焊道进行了物理、化学和机械性能测试．结果表明：焊缝性能满足要求，可以获得优质堆焊焊道．Using a self-made microcomputer controlled strip surfacing equipment and agglomerative flux,the investigation of high-speed surfacing with the strip of 75 mm×0. 4 mm is carried out. The factors and rules which influence the appearance and the dilution of the weld are found out. According to this investigation, the optimum welding condition parameters are given. The bead of high quality can be obtained by using these parameters. The physical, chemical, and mechanical propertise are experimentally determined. The experimental results show that these proportises meet the technical requivements of the process.
