[0002] In recent years, in the field of pressure vessel manufacturing, round cylinders are a very common structure. The cylinders are made of bent and welded plates. However, due to the thick thickness of the plates, their heavy weight and the stress generated during welding, the welded cylinders are often not round enough, making it difficult to connect to the curved base, and the pressure-bearing capacity of the non-round cylinders is also poor. Therefore, after welding, the cylinders need to be tested for roundness using detection tools and re-calibrated.
