“…Only one published paper [1] has been found that applied a rigid body motion vibration to the specimens and found an improvement in mechanical properties of the material. Munsi [2], Aoki and Nishimura [3], Aoki et al [4], Maekawa et al [5] and Nakagiri et al [6] have investigated 'during-welding' treatments. The results of those investigations were mixed, in that some found a reduction in residual stresses and the others concluded with a negative comment.…”

Previous studies have suggested that weld microstructure may be modi ed by the presence of static stresses. In this investigation, vibratory stress was applied to mild steel specimens while they were being welded to observe its effect on the residual stress, microstructure and hardness of the material. Residual stresses were found to decrease in response to vibration whether it was applied during welding or after welding. It was found that the applied stress in uenced the grain growth process in the weld. As a result of the treatment the hardness of the material was found to be increased by 25 per cent.

“…It has been established that both 'during-welding' and 'post-weld' vibration treatments can reduce residual stresses [2][3][4][5][6][7][8][11][12][13][14]. It has also been established that uniaxial stress causes a change [15] in the grain orientation, and vibratory stress causes grain re nement [16] in cast irons.…”
