近年来,我国的焊接生产有了很大的发展。在焊接生产中,焊接变形的问题,常常使人们感到头痛;它也给焊接的进一步推广造成一些思想上的障碍。焊接后结构会产生变形,这是不可避免的。但是,人们对于焊接变形也不是无能为力的。当我们掌握了它的规律以后,我们是可以防止或减小焊后的变形的。在这里,我们将讨论不同的焊接情况所产生的不同的变形。了解了这一些规律,我们就可以在实际生产中充分考虑防止和消除变形的方法。
In recent years, China’s welding production has made great progress. In welding production, the problem of welding deformation, often make people feel a headache; it also caused some ideological obstacles to the further promotion of welding. Structure will be deformed after welding, which is inevitable. However, people are not powerless to welding deformation. When we have mastered its laws, we can prevent or reduce the deformation after welding. Here, we will discuss the different deformations caused by different welding conditions. Understand these rules, we can fully consider in the actual production to prevent and eliminate the deformation method.
