我厂七车间革命职工遵照毛主席关于“破除迷信,解放思想”的教导,经过多次试验,成功地采用了后桥半轴焊接工艺,经上海材料应用科学研究所在试验机上作扭力试验,采用焊接工艺的后桥半轴扭力负荷在600公斤·米时未被扭断(试验机最大扭力负荷为600公斤·米),另外我厂又用50余根后桥半轴进行装车试验,经使用均未发现焊接处断裂,质量检定符合要求,现已陆续投产使用。
Following the guidance of Chairman Mao on “breaking superstition and emancipating the mind”, the revolutionary workers of our factory have successfully adopted the semi-axial welding process of the rear axle after many tests. After torque test on the testing machine of Shanghai Institute of Applied Materials, The semi-axle torque load of the rear axle with welding process was not broken at 600 kg · m (the maximum torsion load of the test machine is 600 kg · m). In addition, I plant with more than 50 rear axle semi-axle loading test, The use of the weld did not find the fracture, the quality control meet the requirements, has been put into operation one after another.
