Overview of aging methods for welding residual stresses
In order to solve the problem of residual stress reduction in welding,the current situation of the influence on the performance and accuracy of welded structural parts is summarized,and several main methods of aging treatment are summarized.According to the analysis,the natural aging method is simple to operate but the cycle is too long,so it is not suitable for enterprise production;The thermal time effect is widely used and the effect is obvious,but the energy consumption is high and there is pollution;Vibration aging is used more in actual production,easy to operate,relatively low energy con-sumption,and is widely used in the manufacturing industry.In the future,attention should also be paid to emerging aging treatment technologies such as ultrasonic failure,which should be applied in combina-tion with the actual production form.
