Abstract

The residual stress and welding deformation were measured for the bogie frame steel plate SMA490BW butt joint welded by using the plasma-MIG hybrid welding process and the general MAG welding process respectively, as well as in different groove angle conditions. The results indicate that the plasma-MAG hybrid welding can effectively reduce the residual stress and the welding deformation compared with the classic MAG welding. With the decrease of groove angles, the residual stress and welding deformation reduced accordingly. From the angle of reducing the residual stress and the deformation, the plasma-MAG hybrid welding process should be adopted in the way of narrow groove.
