An Introduction To NDT Companies

NDT companies employ techniques that evaluate the properties of an object without breaking it down. Non destructive testing has a lot of uses in many industries. It reduces the expenses of a company and reduces the time needed to gather data.

To determine the nature of a substance, electromagnetic radiation can be used to look at the interior. Sound waves can also be utilized for further assessment. Some use dyes, chemicals or iron pieces for testing. The thermoelectric effect can also be used to assess a material.

Non destructive testing is often used to assess structural integrity and look over an object for flaws. This is especially helpful in manufacturing, construction and various stages of product development. It improves the reliability of a material and makes sure that the final product adheres to specifications. Because of the tests do not destroy the sample; it can still be used for other tests to confirm the results.

NDT inspections will allow inspectors to find defects in the structure of a product. Evaluations that use ultrasonic testing can reveal flaws in structures like aircrafts, and even the human body. X-ray has been used to inspect body parts without the need for surgery. Dye penetration testing make cracks visible by glowing or changing in color.

Eddy current testing can be used to bring out structural irregularities not visible to the naked eye. Strain gauge tests gather data about the effects of strain on an object. Industrial applications of these tests include welding to evaluating the soundness of bridges and buildings.

In this field, technicians have to undergo NDT training courses and obtain a certification. This qualification is important since these technicians will be called in to make significant decisions that will have far reaching consequences. They not only help ensure safety, they can also cost the company a lot of money if they are not competent.

Through training, a technician will increase his proficiency. Training under a higher level personnel will give him more skills and knowledge. The final phase of the certification is the examination which the technician will have to pass. Certifications are granted for each of the method so a technician may opt to acquire several.

These certifications are divided into three competency levels. Level one technician have limited abilities and are only allowed to do specific tests. They are under the supervision of more competent technicians. Level two is assigned advanced tasks while level three technicians have enough skills to interpret regulations, design methods and decide which is ideal. Through these certifications, NDT companies can be assured that there technicians are competent.
