Magnetic Particle Inspection is used to detect discontinuities on and near the surface of ferromagnetic materials. The process involves magnetizing the test object. A discontinuity in the metal's surface will cause the magnetic field flowing through to be interrupted, causing a leak. Small iron shavings are applied to the test object, and they will gather in the leaks. This allows people to see where the indications are on the test object. Magnetic Particle Inspection is commonly used to test welds, tools, castings, and more for quality control, code compliance, and surface integrity purposes.
The iron particles used in MT can be wet or dry. Dry particles are easy to transport, but they are not as effective. Wet particles are suspended in a liquid. Combining the wet particles with a black light makes the indications clearly visible. This option is usually used in a laboratory setting.
Unmanned Aerial Vehicles (Drones) have recently gained in popularity for business and personal use. AER is currently exploring how drones can be used to increase safety in the field of non-destructive testing.
Some areas that need inspection are rooftops, tall buildings, bridges, and large storage tanks. To reach these areas, workers normally set up scaffolding, ladders or machinery. This can be dangerous and scary, especially for a person who is afraid of heights. A worker could fall, or tools could be dropped on a worker below. Everyone is exposed to safety hazards.
A solution is to use drones to reach the high areas and perform inspection. High resolution cameras and infrared cameras can be attached to the drone, and workers are able to inspect tall objects with their feet on the ground. Some parts may need further inspection, but the use of drones helps workers to minimize the amount of time they are in a hazardous situation.
Common places non-destructive testing is performed is at gas compressor stations, power plants, and nuclear facilities. Performing inspection in these areas exposes workers to harmful gases and radioactivity. Workers can attach a sensor to a drone and fly it into a hazardous area to check for harmful gases and radioactivity. Workers are able to assess and area while staying safe.
With worker safety as a top priority, AER is actively working with regulatory agencies to explore the benefits of using drones for visual and thermal assessments under 250 ft.
I recently attended an ISNetworld conference in Pittsburgh to learn about their services, marketing, and what hiring clients look for in a company's profile. I found the meeting and the opportunity to network afterwards beneficial. I now have a better understanding of how to use ISNetworld in ways to benefit AER.
ISNetworld recently expanded their services and updated the look of the website to make it more user-friendly. They went into detail about their Training Manager service. Companies can use this to keep track of their employees' training. The calendar keeps everything organized, and it tells you when an employee has completed the training. A benefit I see is it will help a company keep up with their training program. One who uses this application is less likely to forget about trainings.
I enjoyed discovering how I can use ISNetworld to better market AER. After the meeting, I updated to company profile to tell more about the services we offer and other general information. I was able to download a certificate of membership, request stickers, and create employee ID cards through ISNetworld. They also mentioned a section of the company profile where companies can upload documents for their connections to view. I used this area to upload all of AER's service brochures.
A panel of hiring clients from large companies were present at the conference to say what they look for on ISNetworld when determining who they want to award work to. The main thing they look for is updated information. It is important to keep safety policies, insurance, and general information up to date on ISNetworld.
After the conference was over, I was able to network with members of the panel. It was beneficial to hear from them the specific way their company finds and hires contractors. The meeting was beneficial, and I recommend other contractor companies on ISNetworld attend one of the conferences as well.

The chart pictured above shows the total number of flaws in a pipeline weld and the number of flaws detected by phased array and radiography, according to thickness. This chart was originally published in a scholarly journal presented at the 18th World Conference on Non Destructive Testing.
The chart shows results of a test performed to see which method has the best ability of detecting flaws in pipeline welds. The question the test was performed to answer is "With phased array becoming a possible replacement for radiography, is it reliable to use in detection of weld defects?" After careful interpretation of the results, the study concludes that the risk of using radiography in terms of reliability increases incredibly as pipe thickness increases. Phased array was able to detect critical flaws as the pipe thickness increased, where radiography struggled to detect these flaws.
Phased array is a quality testing method, and its detection ability is really shown when it is used on thick pipeline welds. It has been said before that the technology can see fly feces. Its detection ability is high, and the use of phased array also allows for the ability to measure and specifically locate the flaw.
When quality is a major concern, phased array is a superior testing method. Its ability to locate flaws has been tested and proven effective.
