How can I assure the quality of my FSW weld?

In order to guarantee the quality of a FSW weld, it is necessary to carry out a study of prototypes in accordance with the ISO 25239 standard. These prototypes are controlled by destructive and non-destructive tests.
Non-destructive testing (NDT) includes both visual surface inspection and volumetric inspection. Some defects are visible to the naked eye, such as flash and wormholes. They can therefore be easily detected. Other NDT tests can be performed using ultrasonic (UT) devices or radiography.
Destructive testing will involve an action on the weld such as a bend test, a tensile test or a macrographic examination.
Thus, once these controls are carried out and validated, the FSW welding can be repeated in an industrialized way, ensuring its quality at 100%.
