NDT Level III Unlimited Certification is reserved for only the top technicians with experience and skill. If you want to do it right, ask the top technicians in the field. Here we'll discuss what NDT methods are most often recommended by Level III Certified technicians?
When you become a nondestructive testing technician, certification is earned in a series of levels. At Level I Limited, Level I, and Level II certification, technicians can take NDT courses at an NDT training institute to learn the craft of nondestructive testing and practice testing methods under the supervision of a highly qualified Level III technician.
To earn Level III certification, technicians must have a strong grasp on a number of different testing methods that meet at least one of the additional requirements:
Possess a degree in engineering or science from a university or college with a minimum of one year of Level II experience in the specific NDT discipline(s)
Passed at least two years of science or engineering study at a college, university, or technical school with two years of Level II experience in the specific NDT discipline(s)
Gained four years of Level II experience in the specific NDT discipline(s)
Clearly, NDT Level III technicians are experts in the field. When it comes to testing methods, these technicians know the inside information on which testing methods are best.
Magnetic particle testing is one of the most commonly used methods in NDT, and it is also one that experts can all agree on.
Magnetic particle testing is a process by which a pigmented powder is applied to the surface of a ferromagnetic asset. Through prodes, yokes, coils, or a central conductor, a magnetic field is then applied to the asset.
The ferromagnetic powder will be drawn into the magnetic leakage field caused by a discontinuity, revealing whether or not a crack is present.
Experts choose this technique because it is a relatively low-cost method, it is highly portable, easy to perform, and it can be used on irregularly shaped assets with ease.
Another method that all expert technicians can vouch for is ultrasonic testing. During ultrasonic testing, high-frequency sound waves travel through the component under inspection. In the event that a flaw is present, the sound waves will hit a part with a different acoustical impedance, which will then reflect back on the sending unit.
The best technicians recommend ultrasonic testing because of its portability and consistency. It is also a desirable method because the results are instant, only limited access to the part it needed, and it can detect both surface and subsurface defects.
If you are looking for nondestructive testing services to protect your assets or to become a technician yourself through NDT technician training, it’s crucial to choose the right NDT training institute to meet your NDT needs.
