Influence of Initial Temperature of Chilling Treatment on Residual Stress State of TIG Dressing Zone for T-Joint Welded Toe


Article Preview

Using finite element method, the residual stress distribution of TIG dressed welded toe followed by chilling treatment with different temperature of steel and aluminum alloy T-joint was calculated. And the residual stresses of welded toe were also measured by using the blind-hole method. The results indicate that with the increase of initial temperature of chilling treatment, the longitudinal residual stresses in welded toe of steel joint are gradually transited from tensile residual stresses to compressive ones, and there is no significant change for transverse residual stresses; and the longitudinal residual stresses in welded toe of aluminum alloy joint are compressive stress and gradually increased, no significant change for transverse residual stresses.
