Аннотация: | This paper deals with vibration treatment during welding process as a way of increasing the accuracy of the geometric shape in the vertical butt joint area and corner weld joint when installing vertical steel tanks from rolls. The rolling method is the most promising and worthwhile method of vertical steel tanks manufacturing. However, during the installation process defect like angularity in vertical butt joint is occurred because of residual welding deformations. Another problem of installation of tanks is the lack of penetration in the T-joint in corner weld joint. Both of these defects influence on fatigue durability of the welded construction of tanks.
Paper discusses the influence of vibration treatment on form of welded joints and level of welding deformations of steel plates. Also parameters of vibration treatment were searched which allow to obtain the best effect of reducing of welding deformations: modes without vibration treatment, with vibration treatment with constant amplitude and vibration treatment with amplitude-modulated signal were considered. |
