Operators in the manufacturing industry need to be able to inspect the quality of their products. Whether a machine is being used for welding, drilling, or any other activity, it’s important that operators know what they’re looking for and how to identify if something is not quite right. Non-destructive testing (NDT) is a technique that helps to detect small flaws and defects in materials without damaging them. Operators who work in manufacturing need NDT training so they can perform inspections effectively on their machines and raw materials before they are put into production. This ensures that only high-quality products are produced and reduces waste. There are many different types of NDT training courses available. Depending on your current job, you may need general NDT training or more specific NDE Certification training. If you work as an inspector, you may also need inspection certification like ASNT Level 2 certification so you can get better jobs with certain companies. Read on to learn more about what you should know about NDT training courses.
What You Should Know About Nondestructive Testing Training
NDT is a controlled way of inspecting materials and components. When a company is making products, they want to make sure they’re of the highest quality and that there are no defects. An NDT inspection can help them do just that. NDT techniques, including ultrasonography (Ultrasonic test), eddy current, magnetic particle, liquid penetrant, and x-ray, allow operators to look into materials without having to cut them open. They can identify defects, investigate issues, and find out exactly what is wrong. And, if a product is not up to standard, they can perform other inspection techniques to repair it.
NDT Basics
During an NDT inspection, an operator will use a machine to send out a signal that travels through the material. If there are any flaws or defects present, they will reflect that signal back to the operator. The operator will then be able to see what the problem is and take the appropriate action. There are many different types of NDT, including ultrasonic, eddy current, x-ray, magnetic particle, liquid penetrant, and infrared thermography. Some types of NDT are used more often than others, depending on the industry and the materials being inspected. For example, x-ray is used often in the aerospace industry while ultrasonic is more common in the oil and gas industry.
Types of Nondestructive Testing
Ultrasonic Testing – This test uses high-frequency sound waves to inspect the welds, austenite, and ferrite in steel. It can also be used to test for flaws in other types of materials, such as cast iron, aluminum, copper, and stainless steel.
Eddy Current Testing – When electricity is passed through a steel surface, the current creates a magnetic field. If there are any flaws in the steel, the eddy current will be disrupted and the signal will be interrupted. This is a common NDT technique used to inspect the surface of steel components.
X-Ray Testing – X-ray inspection is used to inspect welds, cracks, and hardness. When beams of x-rays pass through a material, they are either absorbed or reflected. Any areas that are softer or have flaws in them will be easier to see on the image because they will be reflected more.
Magnetic Particle Testing – In this test, a magnet is used to determine if there are any inclusions (or contaminants) in the material.
Liquid Penetrant Testing – This test is used to inspect welds and other joints in a material. When a pigmented liquid is applied to a surface, it will run off any areas that have holes or cracks in them.
Why Get NDT Training?
Operators who are trained in NDT are able to find tiny defects in materials that may not be visible to the naked eye. This helps companies to ensure that the materials they use are of high quality and are able to withstand the pressures and stresses they might be exposed to once in operation. It also helps reduce the chances of a defective product being shipped out. NDT training is also required if you want to get accredited. You’ll need NDT certification to get hired as an inspector and be able to inspect materials and products for a company. Most industries require NDT testing when raw materials are being selected, when equipment is being repaired, and when new equipment is being purchased. It is also used to determine if something is acceptable for use.
Which NDT Course Is Right for You?
Depending on the type of inspection you’re doing, you may need a specific NDT training course. You can find a list of the different NDT courses and their descriptions on the American Society for Nondestructive Testing website. Once you know what type of inspection you need to perform, you can then look for the right NDT training course. NDT training courses are available at many community colleges and other institutions. You can also find online NDT training courses you can take from the comfort of your own home.
Bottom line
When you’re inspecting materials, you’re looking for defects such as cracks or pores in a weld and inclusions in a casting. You may also have to detect other defects such as voids or misalignment. When you’re inspecting components, you may have to use ultrasonic or electromagnetic techniques. If you work in manufacturing, you may need to be trained in NDT techniques. These techniques allow you to inspect materials without damaging them. NDT training comes in many different types and can help you get a better job.
