Failure to properly qualify and track materials can lead to premature failure of components.
- Process Control and Validation
Swaging processes must be carefully controlled and validated to ensure consistent results. This includes monitoring and controlling parameters such as force, speed, and temperature. Statistical process control (SPC) techniques are often employed to track process variations and identify potential issues before they lead to defects. Validation procedures, such as destructive testing and non-destructive inspection, provide empirical evidence that the process consistently produces components that meet required performance characteristics. Example: radiographic inspection of swaged joints to ensure the absence of voids.
- Non-Destructive Testing (NDT)
NDT methods are indispensable for detecting internal flaws and inconsistencies in swaged components without compromising their structural integrity. Techniques such as ultrasonic testing (UT), radiographic inspection (RT), and dye penetrant inspection (DPI) are used to identify cracks, voids, or other defects that could compromise the component’s ability to withstand operational stresses. NDT is often performed on 100% of critical components to ensure the highest level of safety and reliability. An example is ultrasonic testing of swaged cable fittings to verify proper material consolidation.
