二步法轴类表面喷焊在喷焊工艺中占相当重要的位置。但喷焊后,加工轴发生弯曲和耗粉量大,直接影响了喷焊质量和成本。在近几年的工作实践中,我们对上述两问题作了一些分析和试验,体会如下: 1.关于解决喷焊后加工轴发生弯曲的问题: 轴在重熔时,由于温度剧烈上升到1000℃左右,一根750mm的拉杆此时线胀量可达5—8mm,如果把它夹在车床 Two-step shaft surface spray welding spray process in a very important position. However, after the spray welding, the processing shaft bending and consumption of powder, a direct impact on the quality and cost of welding. In recent years of work practice, we have made some analysis and test of the above two issues, the experience is as follows: 1. On the solution to the problem of bending the shaft after spray welding: axis remelting, the temperature rose sharply to 1000 ℃ or so, a 750mm rod at this time line up to 5-8mm, if it is caught in the lathe
