| Abstract: | Most of hydraulic steel gates are large weldments subjected to high weld stress. Stress relief may affect the dimension accuracy and material mechanical property of gates. Taking the plane steel gate treatment of Songshu Reservoir in Liaoning Province as example,an introduction was made on the technical principles,methods and da-ta selection for elimination of residual welding stress and vibration aging treatment. |
