Causes of deformation and stress tend to reduce the quality of the welded ball screw
Welding deformation and stress tend to degrade the quality of the welded ball screw, or the next step can not be carried out, and the correction deformation sometimes consumes several times the welding time and materials, and in some cases even has to be scrapped because it cannot be remedied. Therefore, to weld a welded structure, it must be considered from the overall structure, not limited to a weld. The generation of welding cracks and welding deformation are also closely related to stress, and the laws of welding deformation and stress must be analyzed in depth. For example, the causes of welding deformation and stress are analyzed. In the analysis, it is necessary to grasp the physical and mechanical properties of the material, that is, the internal factors of deformation and stress. At the same time, it is necessary to understand the external factors such as the thermal process of welding and the rigidity of the component. The external cause works through internal solids. Without such analysis, it is impossible to have a deep understanding of deformation and stress. It is impossible to find a way to deal with deformation and stress from the actual situation. Welding deformation is a bad thing under normal circumstances, but the mechanism and law of deformation can be mastered, and the deformation can be performed, that is, the deformation can be used to correct the deformation, and the deformation can be used to achieve the requirements of the welded structure.
