通过一例机车轮箍崩箍的检验分析得知，机车轮箍轮芯挡局部缺肉处进行焊补，焊补金属处出现的裂纹和凹坑导致轮箍径向脆性崩箍。建议在轮箍生产和维修中严格依照规定进行操作。 According to the test and analysis of a locomotive wheelhouse collapsible collar, it can be seen that the locomotive wheel and wheel hub block is partially welded and repaired by welding, and the cracks and dimples in the weld metal cause the radial collapse of the wheel rim. It is suggested that the operation and production of the tire be carried out in strict accordance with the regulations.
