Tests of residual stress on welded structures under vibratory stress relief

Shun Fenghua;Fang Dexin( Dept. of Engineering Mechanics,DUT)  
This paper presents the resuIts of the tests of residual stress on some kinds of weldedstructures, which are in the conditions before and after heat treatment or vibratory stress reliefby blind-hole,and concludes that residual stress in welded structures can be relieved and becomestable by VSR technology and that it is more efficient than heat treatment in the field of stressrelief.So,vibratory stress relief is a new feasible technology.
