As a nondestructive testing technician, there are a wide variety of fields in which you may work to ensure safety and protect the daily operations of industries like infrastructure, transportation, and renewable energy.
Nondestructive testing as a practice is equally diverse in the types of inspection methods used by technicians every day to test for flaws.
Nondestructive testing technicians earn NDT certification in a variety of methods while in NDT courses. Among liquid penetrant testing and ultrasonic testing, magnetic particle testing is one of the most commonly used methods of nondestructive testing.
While magnetic particle testing is a popular method of nondestructive testing, there is a reason that there are so many different ways to inspect assets with nondestructive testing-- not all methods will be appropriate for every job.
It is the role of a nondestructive testing technician to decide which testing method will yield the best results. Check out these tips from TXNDT on deciding when magnetic particle testing is the best method to use.
Magnetic particle testing is a nondestructive testing method that uses magnetism to detect flaws and inconsistencies in an asset under inspection.
During this process, a fine pigmented ferromagnetic powder is applied to a ferromagnetic asset. Using a variety of direct and indirect methods like yokes, prods, or coils, a central conductor will create a magnetic field. If there are any inconsistencies, the powder will be drawn into the area, indicating the crack or flaw.
First and foremost, a technician should only be using magnetic particle testing on an object that is ferromagnetic. If you are working with a material like steel, cobalt, iron, or nickel (to list a few), the ferromagnetic pigmented power will help to yield precise results indicating if a flaw is present.
Magnetic particle testing is also a great idea when you are looking to cut costs. It’s a low cost inspection method that is also easy to perform and highly portable. Your company can cut out a variety of costs like expensive equipment, as well as the high costs that can come with transporting assets or equipment. In other words, when you are looking for a low-cost method that yields precise results, there may be no better choice than magnetic particle testing.
Magnetic particle testing is an excellent method of nondestructive testing, but an inspection method is only as good as the skills of the technician performing it. The road to becoming a great technician begins with top-tier training.
