%X n this research, welding joints of steel 16Mn in the same state of initial microstructure and residual stress were subjected to shock wave with different intensity by changing the distance between explosive and the sampling location of the specimen. The rotational bending fatigue limits of steel 16Mn welding joints and the ferrite dislocation morphology were studied resistively before and after the explosion treatment within the zones affected by the plastic, elastic and elasto-plastic shock wave. And the mechanism of improving fatigue limits of steel 16Mn weld as a result of the explosion shock wave act was brought out with dislocation tangled and pined theory.
