在修复磨损的球墨铸铁曲轴轴颈时,可以使用如下一些修复方法:用钢带制成环再堆焊;在20％甘油溶液中作振弧堆焊;自保护焊丝C_B—15堆焊;粉末焊丝—AH122作双层堆焊;在AHK—18(70％)和AH—60(30％)的熔剂下用C_B—08焊条的双电极堆焊;等离子金属喷涂以及采用附加零件的修复工艺。 堆焊过程同被修复零件的热输入有关,也同出现翘曲、白口、微裂纹
The repair of worn nodular cast iron crankshaft journal, you can use the following repair methods: ring made of steel and then re-surfacing; in 20% glycerol solution arc welding; self-shielded welding wire C_B-15 surfacing; powder Wire-AH122 for double-layer surfacing; double electrode surfacing with C_B-08 electrode with AHK-18 (70%) and AH-60 (30%) flux; plasma sprayed metal and repair using additional parts. Surfacing process is related to the heat input of the repaired parts, also appear warping, white mouth, micro-cracks
