| 摘 要： | 试验以QT600-3为研究对象,采用电弧钎焊,以锡铅合金为钎料,对其进行补焊.通过对钎料润湿性、焊缝结合情况、显微硬度、微观组织分析,发现钎料能润湿铸铁表面,焊补试验初步实现铸件的低温补焊,做到了高效率、无焊接变形、无色差.钎焊接头在高温停留时间短,但冷却速度快,仍存在白口化问题,可用于非加工面的缺陷修复,挽救了大量铸铁件并节约了大量资金.

| Abstract: | Welding repair saves lots of money.The experiment was based on QT600-3,and leypewter was used as the filler metal for arc brazing.The filler metal could wet the base metal by the analysis of the wettability of the solder,the joining of the weld,the microhardness,microstructure.Experiments preliminary achieve the target of cryogenic welding repair with high efficiency,and the weld had a good appearance with no welding deformation and color difference.The weld of arc brazing stayed at the high temperature for... |
