This shaft was spot weided (using an MIG weiding system) at its mid-length to induce residual stresses,as shown in Fig.2.The welding process was carried out in a fraction of a second.The shaft was allowed to cool to room temperature and the residual stresses were measured.The shaft was then vibrated.The applied shear stress to the shaft was varied from 0 to 65.4 MPa in several steps (shown in Fig.9).The time of vibration at each stress step was 1 min at a frequency of 25 Hz.A lineof 5 mm length was selected for investigation.Similiar to shaft 1,residual stress measurement was carried out at intervals of 0.2 mm.The measurement was carried out on the as-drawn surface;no surface preparation was carried out.The measurement was started at the weld toe.The residual stress are shown in Fig.9.
For a small applied shear stress(±17.5MPa),the residual stresses were almost unchanged (Fig.9).With increase in the applied stress to ±30.8MPa,the residual steesses on and near the weld toe decrea

楼主大概就是什么翻译公司拿来的试译稿吧。
