How do you use Spotcheck SKL SP2?

How do you use Spotcheck SKL SP2?

Apply penetrant SKL-SP2 to the clean component and allow contact time. Spray component with water to remove excess penetrant. Immerse component in hydrophilic remover ZR-10C for the predetermined time. Spray component with water to remove last traces of penetrant.

How do you use penetrant dye?

There are six basic steps to follow when using the dye penetrant solvent removable method.

1. Pre-clean part. This can range from grinding and wire brushing to merely wiping the part with a rag moistened with the cleaner/ remover.
2. Apply penetrant.
3. Remove penetrant.
4. Apply developer.
5. Evaluate indications.
6. Post-clean part.

1. Penetrant. Apply the penetrant to the test area. Allow the penetrant to dwell for 10-30 minutes.
2. Developer. Apply the developer to the test area. Allow the developer to dwell for 10-60 minutes.
3. Inspect. Examine the part for any bright, clear indications.

What is the disadvantage of the liquid penetrant test?

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.

What is Magnaflux used for?

Magnetic particle (Magnaflux Inspection) inspection is a method for detecting cracks, laps, seams, voids, pits, subsurface holes, and other surface, or slightly subsurface, discontinuities in ferro-magnetic materials. Magnetic particle inspection can be used only on ferro-magnetic materials (iron and steel).

What is the disadvantage of dye penetrant inspection?

With this method, only surface breaking defects can be detected. It is possible to inspect only materials with relatively nonporous surface. It is necessary to pre-clean the material since contaminants can mask defects.

What is dye penetrant testing used on?

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.

What is the purpose of dye penetrant?

What are the limitations of dye penetrant inspection?

DISADVANTAGES

• With this method, only surface breaking defects can be detected.
• It is possible to inspect only materials with relatively nonporous surface.
• It is necessary to pre-clean the material since contaminants can mask defects.
• Metal smearing from machining, grinding, and grit or vapor blasting must be removed.

How does a Magnaflux machine work?

Electric Current passing through a wire wound into a coil creates a magnetic field lengthwise inside the coil. 2. When a part is placed in a Magnaflux® Unit inside a coil carrying electric current, a magnetic field running lengthwise of the part is created. This is Longitudinal Magnetization.
