Classifying the circumferential joints between ball heads and cylinders, as well as the butt welds between embedded nozzles and cylinders or flanges, as Class A is to indicate their importance. The misalignment allowance for Class B is intended to reduce the requirements regarding alignment dimensions to facilitate practical operation, as the alignment of these welds is similar to that of Class B welds

a. Class A weld joints: The stress levels in the longitudinal ring welds of spherical heads are consistent; therefore, the circumferential joints that connect the hemispherical heads to the cylinder are also classified as Class A.
