How do you become a magnetic particle inspector?
To become a Level I inspector, you must complete 16 hours of training, 130 hours of work experience, and pass a certification exam. Some programs, such as the one offered by the NDT Training Center, combine Level I and II training, allowing you to move directly to Level II.

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.
What does magnetic particle testing detect?
Magnetic Particle Testing (MPT), also referred to as Magnetic Particle Inspection, is a nondestructive examination (NDE) technique used to detect surface and slightly subsurface flaws in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys.
What is MPI in mechanical engineering?
Magnetic Particle Inspection (MPI) is a non-destructive testing method that can detect surface and subsurface flaws in ferromagnetic materials. Magnetic particle inspection is often carried out to help determine an item’s fitness for use or conformity.
How do you perform an MPI inspection?
Magnetic Particle Inspection is performed in four steps..
- Induce a magnetic field in the specimen.
- Apply magnetic particles to the specimen’s surface.
- View the surface, looking for particle groupings that are caused by defects.
- Demagnetize and clean the specimen.
What is the difference between NDT and MPI?
Magnetic particle Inspection (MPI) is a nondestructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part.
What is MPI in engineering?
What is MPI in welding?
Magnetic Particle Inspection (MPI) is a very effective method for location of surface breaking and slight sub-surface defects such as cracking, pores, cold lap, lack of sidewall fusion in welds etc in magnetic materials. There are many different techniques.
What is the acceptance criteria for MPI?
Code Acceptance Criteria for Magnetic Particle Inspection Rounded indication with size greater than 3/16 inches. Four or more rounded indications in a line separated by 1/16 inches or less. Crack-like indications, irrespective of surface condition.
Which material Cannot be tested by MPI?
9. Which of the following material can’t be tested by magnetic particle testing? Explanation: Magnesium (Mg) is a non-magnegnetic material. So, it can’t be tested by magnetic particle inspection.
What is the difference between MPI and UT testing?
As discussed previously, MPI is only used on ferromagnetic materials. Joint configuration and accessibility of the welded joint are two other factors that determine the NDT method used. While UT is good for joints with limited access to both sides.
