Press fitting and method to monitor and assess the quality of a press-fitting

Press fit has second component (3), which is formed in such a way that an increased joining pressure is generated in the pressing direction at end section (5) of press fit. A locally higher interferences and/or locally higher stiffness in second component is formed causing local constriction (6) of mounting hole (4) and making a roundness. Limited joining pressure is selected to attain tight lip seal action. An independent claim is also included for a method for monitoring and evaluation of the quality of press fit.
