What is Zyglo testing?

What is Zyglo testing?

Zyglo® is the preferred penetrant inspection method for the extremely sensitive fluorescent detection of cracks and surface discontinuities in ferrous & non-ferrous test materials.

What is the principle of liquid penetrant method?

The principle of liquid penetrant testing is that the liquid penetrant is drawn into the surface-breaking crack by capillary action and excess surface penetrant is then removed; a developer (typically a dry powder) is then applied to the surface, to draw out the penetrant in the crack and produce a surface indication.

What is MagnaFlux and Zyglo?

MagnaFlux Zyglo ZL-27A Post Emulsifiable Fluorescent Penetrant. ZL-27A Post Emulsifiable Fluorescent Penetrant is resistant to water to prevent over washing.

How many methods Zyglo testing involves for removing the penetrant?

T h e re are four primary methods for removing or cleaning surface p e n e t r a n t s .

What are the different steps of liquid penetrant testing?

Liquid penetrant examination is one of the most popular Nondestructive Examination (NDE) methods in the industry….There are six basic steps to follow when using the dye penetrant solvent removable method.

  • Pre-clean part.
  • Apply penetrant.
  • Remove penetrant.
  • Apply developer.
  • Evaluate indications.
  • Post-clean part.

Where is liquid penetrant testing used?

Dye Penetrant Inspection (DPI) is widely used to detect surface breaking flaws. This non-destructive testing technique, also known as liquid penetrant inspection (LPI), is a cost-effective method used to locate surface breaking flaws such as cracks, porosity, laps, seams and other surface discontinuities.

Which penetrant method is the easiest to use?

Since visible dye penetrants do not require a darkened area for the use of an ultraviolet light, visible systems are more easy to use in the field.

Which level penetrant is most sensitive?

Understand fluorescent liquid penetrant sensitivity levels and how to find the right one for your application

  • Level ½ – Very low sensitivity.
  • Level 1 – Low sensitivity.
  • Level 2 – Medium sensitivity.
  • Level 3 – High sensitivity.
  • Level 4 – Ultrahigh sensitivity.

Which method of penetrant removal is solvent removable?

Method C
Method C, solvent-removable, penetrant removal technique relies on a solvent-based cleaner, like SKC-S NDT cleaner/remover, to remove the penetrant from the part being inspected.

What are the limitations of liquid penetrant testing?

Liquid penetrant testing has the following disadvantages:

  • Extensive, time-taking pre-cleaning critical—surface contaminants can mask defects.
  • Sensitive to surface-breaking defects only.
  • Direct connection to the surface under test necessary.
  • Works on relatively non-porous surface materials only.
  • No depth sizing.
