Abstract:  
The CREUSABRO 32 steel [1] TIG-welded joints were investigated before and after shot peening by mean of x-ray analysis and micro-hardness measurements. Fatigue tests were carried out to study and to optimise the shot peening parameters to improve the fatigue resistance of the welded jounts. Beneficial effects of shot peening has been observed and 54% increase was noted for the used Almen intensity of 16-20 A.
