半轴是机械动力的主要零件,由于材料欠缺(大部分依靠进口)以及半轴断裂的现象经常发生,严重影响设备的运转,为了解决这一问题,我们对半轴的修复做了大量的试验工作,终于用局部预热电焊法成功地修复了断裂的半轴,为国家节约了大量资金。以日本 KM100型吊机半轴为例,半轴 Axle shaft is the main part of the mechanical power, due to lack of material (mostly imported) and the phenomenon of shaft rupture often occur, seriously affecting the operation of equipment, in order to solve this problem, we have done a lot of tests on the repair of the shaft Work, and finally with local preheat welding method successfully repaired the broken axle, saving a lot of money for the country. Take Japan KM100 crane half shaft as an example, half shaft
