The paper is devoted to the evaluation of the stressed state of the shell containing two common
defects in the weld shape – angular and axial misalignment at the same time. Expressions for stress resultants and
stress concentration factors for axial and angular misalignment are proposed. The analytical approach is tested
by means of numerical calculations for the internal pressure
