MPI examines ferroelectric materials like steel, chrome moly and nitriding for surface and slightly subsurface imperfections. First a magnetic field is created around or through the part, and then we add ferrous iron particles, which flock to the site of any leakage (we call this an indication). From there, we evaluate what the problem is, where it came from, and what to do about it.
This is a widely used, low-cost method for detecting open to surface indications in all kinds of materials (metals, plastics, ceramics, etc.). By applying a penetrant to a casting, forging or welded surfaces, we can find manufacture issues in new products, fatigue caused by age and use, and welding discontinuities.
UT is often used to monitor pipework corrosion by measuring thickness, but it is also useful on metals, concrete, wood, and composites. This form of nondestructive examination sends short ultrasonic pulse waves into materials to detect internal flaws.
This test mainly finds flaws in carbon steel pipes and tubes. A transmitting coil emits a magnetic field which travels outside the pipe and back in again where it reaches the receiving coil. This coil can detect any variance in the strength of the returning current, telling us there may be a flaw which allowed the current to travel with less resistance.
This is pretty much what it sounds like. We test the strength of a material based on its resistance to change when excess force is applied. There are three types of hardness - scratch, indentation, and rebound hardness. This test is useful on ceramics, concrete, and some metals.
This is our way of making sure that the systems in place work to achieve maximum quality. It assures that the product is fit for the purpose it is intended and that all mistakes are eliminated so it’s right the first time.
A simple form of electromagnetic testing which shows a defect in a material based on interrupted or uninterrupted flow of current between two magnetic fields. Simple.
We assess a metallic material based on its elements using X-ray Florescence and Optical Emission Spectrometry.
This is how we determine general classifications of ferrous materials. The system relies upon spectroscopy, spectrometry, and other methods to "observe" the spark pattern. It has been found that this system can determine the difference between two materials that give off sparks that are indistinguishable to the human eye.
