Wet Type SPM

Water or Wet Testing- This method is used as is a secondary method of testing any enclosed component. In this method the component to be tested is first fully enclosed and a pressurized air is passed through it as like dry testing the pressurized air in the component. After that component deep in water tank which is held below the working table. It is noted that if the pressure increases uniformly in the enclosed component, that means the component is okay. But if the pressure suddenly drops and bubbles occur that means the component has a crack, then the component is rejected.
