Ultrasonic UT Testing & Training
Ultrasonics, UT Ultrasound inspection process is a versatile inspection technique. It is used to test a variety of both metallic and nonmetallic products such as welds, forgings, castings, sheet, tubing, plastics and ceramics. Ultrasonics has an advantage of detecting subsurface discontinuities with access to only one side of the specimen.
The objective of UT ultrasonic testing is to ensure product reliability by means of:
- Obtaining information related to discontinuities.
- Disclosing the nature of the discontinuity without impairing the usefulness of the part.
- Separating acceptable and unacceptable materials in accordance with predetermined standards.
In order to provide nondestructive ultrasound testing you usually need to be qualified and certified in accordance with a standard, procedure or practice. You will often here people say you need to meet ASTM, which guides you to SNT-TC-1A a recommended practice or NAS-410 a standard. The important part is to know what you need to meet. This allows you to know which procedures you can follow or which parts you are authorized to inspect.
