Camlock coupling Deformation Reason and Its Solution

The buckling deformation of the camlock coupling is related to the plate width, plate length, welding line energy and welding residual stress. When the ratio of plate width to plate length is constant, the critical thickness does not increase with the increase of plate width, while the critical thickness increases with the increase of width-length ratio . With the increase of the welding wire energy, not only the deformation of the weldment began to aid the time, but also the ultimate deformation of the weldment increases.

Since buckling deformation of the camlock coupling is caused by residual compressive stress,in order to avoid buckling deformation, the welding residual stress value must be lower than a certain critical stress, which can be reduced by reducing the amount of welding and welding line energy and other ways to reduce the pressure Residual stresses in welded structures. Under the conditions of the use of intermittent welding, welding can be reduced by half, so that the residual stress is greatly reduced. Another approach is to reduce the size of the weld, but also can achieve the same purpose.
