Experimental Study on the Effect of Welding Residual Stress Relief by VSR Method

Abstract:

Based on the mechanism of vibrating stress relief and standard of JB/T5926-2005, vibrating stress relief method is used to eliminate residual stress of crane beam flange with butt weld. The welding residual stress of measured points is obtained by using blind-hole method. Experimental results show that the peak value of residual stress is reduced significantly, and the stress decline rate of residual stress is greater than the minimum requirement value of JB/T5926-2005. The effect of VSR method is remarkable.
