Non-destructive testing (NDT) is a type of physical examination that does not alter the material being examined. It is used to detect internal defects in a material, but it will not provide conclusive evidence that something is wrong with the material.
NDT testing is done by using equipment such as microscopes and x-rays to examine materials that are too large or too expensive to be destroyed for testing purposes. It is also used for non-visible parts of equipment such as pipes and tanks.
There are several different types of NDT including ultrasonic testing, magnetic particle inspection and liquid penetrant inspection. Each type uses its own type of equipment with varying degrees of sophistication depending on what needs to be tested.
For example an ultrasound machine looks like a large microphone that emits sound waves into an object whose echo can then be analyzed by software that interprets what it sees in terms of defects present within the object being inspected.
Non-destructive testing services are a valuable resource for any company that needs to inspect the structural integrity of its products. These services can be used on all types of materials, including metals and plastics, as well as ceramics and composites.
When you choose non-destructive testing, you can inspect your products without having to remove them from their packaging. This means that you can test multiple items in one batch, which helps to reduce costs and save time.
The following are some of the types of non-destructive testing services that are commonly offered by companies:
X-ray radiographs: X-ray radiographs are used for examining welds, joints and seams in metal parts to find cracks or flaws that may affect the strength or durability of an object. X-rays can also be used to examine cracks inside objects such as pipes and cylinders.
Magnetic particle inspection: Magnetic particle inspection uses magnetic particles suspended in liquid to detect surface defects such as porosity and corrosion beneath an object’s outer surface by adhering to these defects when they come close enough to them during normal usage conditions.
If you’re looking for a company that offers non-destructive testing services, here are some things to consider:
One of the most important aspects when choosing non-destructive testing services is knowing what type of material you’re dealing with. For example, if you’re working with metals, ultrasonic testing is a good option because it allows for non-contact eddy current measurements without touching the metal surface and without causing damage to the metal under test. If you’re dealing with concrete or wood products, magnetic particle inspection may be a better option since these materials can’t be easily penetrated using ultrasound waves like metal can be.
Another important consideration when choosing non-destructive testing services is whether or not you need a portable solution or if you want something that’s more stationary. There are many portable options on the market today including ultrasonic flaw detectors and eddy current testers that make inspecting items easier than ever before.
You’ll need to schedule your test so it doesn’t take longer than necessary and interfere with your production schedule. Some tests require only a few minutes while others may take several hours or even days. If you need more time than expected, check if there’s any additional charge for doing so before agreeing to anything else your provider suggests during the inspection process.
