What is a whirlpool of current inspection?

The Inspection of the Whirling current is the process of testing materials, which relies more on electromagnetic waves than on physical or mechanical test methods. These inspections are used on a wide range of products, from aircraft to machinery. Erdy is also widely used in the construction industry to test materials such as steel and other metals. This test process can also be known as Foucault the current test or inspection.

During the whirlpool inspection, the coil is made of some type of conductive material such as copper, located near the building that will be tested. The current passes through the coil that creates an electromagnetic field. This electromagnetic field causes a similar contradictory field known as a whirlpool, takes place in the tested object. The currents are then measured using the whirlpool inspection device, usually a portable oscilloscope. Any distortion or discrepancies in the currents indicate deficiencies or cracks inside the test object.

This test method is often used to find deficiencies, cracks or steel welding errors or other metal subjects. The Inspection of the whirlpool can also be used to measure the thickness of the coating or surface on the metal object, or even to determine the material of the object. For example, electromagnetic waves move at a certain speed when passing steel, but they can move differently when copper or brass pass. This test can help determine what type of metal the object is made without removing its surface treatment.

Eddy Current Inspections offer a number of advantages over other test methods. The primary benefit is their non -destructive and non -invasive nature. This means that the object can be tested without damage or destruction and can usually be tested without physical contact. The Melicous Inspection is relatively fast and easy to form and the device used during these tests is portable and with sNadno is operated.

There are also a number of potential disadvantages that should be considered before carrying out the swirling current inspection. First, this test can only be used on conductive materials, so most non -metallic objects will be ineffective. Some surface materials can distort the results of this inspection and the best results can be found on non -covered buildings. Finally, the whirlpool tests may not be able to detect deficiencies or cracks deep in the object and are better for detecting surface cracks.
