What are the five steps involved in performing a magnetic particle inspection?
Steps for Magnetic Particle Inspection
- Surface Preparation:
- Inducing a Magnetic Field:
- Applying Magnetic Particles on the Test Surface:
- Examine the component surface for defects.
- Repeat the test by changing the magnetic field.
- Demagnetization and Cleaning:
What is the purpose of magnetic particle testing?
Magnetic particle testing is a non-destructive process used to detect surface and subsurface discontinuities in ferromagnetic materials like nickel, cobalt, iron and their alloys.
What method of magnetic particle inspection is used most often?
Eddy current inspection. What method of magnetic particle inspection is used most often to inspect aircraft parts for invisible cracks and other defects? Continuous.
What is magnetic particle method?
The magnetic particle test method of Non-Destructive Examination was developed in the USA, in the 1930s, as a way to check steel components on production lines. The principle of the method is that the specimen is magnetised to produce magnetic lines of force, or flux, in the material.
Why is magnetic particle inspection done for ferromagnetic materials?
Magnetic particle inspection is used for detecting defects (discontinuities in surfaces and shallow subsurfacaes) in ferromagnetic materials. By magnetization of the inspected area there is created a magnetic field. A number of forces influence ferromagnetic particles in the magnetic field above the defect.
Is an inspection method for magnetic objects?
Fluoroscopy is a method of non-destructive inspection that has been developed after radiography. Explanation: The inspection method is performed on magnetic objects and used to determine cracks, laps, etc. On the material or part being inspected is called as magnaflux.
What is the principle of magnetic particle inspection?
The principle of the method is that the specimen is magnetised to produce magnetic lines of force, or flux, in the material. If these lines of force meet a discontinuity, such as a crack, secondary magnetic poles are created at the faces of the crack.
What method of magnetic particle inspection is used most often to inspect aircraft parts for minute or invisible cracks?
Which of the following metals can be inspected using the magnetic particle inspection method?
Because this method relies on a magnetic field to produce results, it works best on ferrous materials, like nickel, iron, cobalt, and some alloys. Components like billets, bars, castings, forgings, fasteners, weldments and extrusions are also commonly tested using magnetic particle inspection.
What materials may be inspected using the magnetic particle inspection method?
The testing medium that is generally used in magnetic partiticle inspection utilizes a ferromagnetic material that has: High permebility and low retentivity….Terms in this set (93)
- Porous plastics.
- Ferrous metals.
- Nonferrous metals.
- Smooth primer-sealed wood.
- Nonporous plastics.
Which of the following material can be tested by magnetic particle testing?
3. Which of the following materials can be tested using magnetic particle testing? Explanation: Among the following materials, only ferrous materials can be tested using a magnetic particle test, which is therefore steel. Brass and bronze are copper alloys and solder is an alloy of zinc, lead and tin.
Which of the following materials can be tested using magnetic particle testing?
