Abstract: Vibration stress relieving is considered a cost-effective alternative to heat treatment for removal of residual stresses caused by the welding process.This paper concerns about the advisability of using vibration stress relief (V.S.R) on drums.The measurements of residual stress in drums were carried out before and after vibratory stress relief,to quantify the change in residual stress achievable in these drums.And the dynamic stress was measured during vibratory stress relief.These results indicate that V.S.R process is effective in the residual stress relief of drums.
