ULTRASONIC INSPECTION

Ultrasonic testing (UT) is a safe and non-invasive technique to detect internal flaws or characterize materials.  It uses high frequency sound energy to propagate through a material and pick up any material change (i.e. cracking) detected.

​

UT can used to measure the thickness of a test item, identify underside corrosion, or weld scanning for internal defects and compliance to an acceptance criteria/code.

​

Ultrasonic testing is commonly used for:

​

• Flaw detection in welds/materials

• Material thickness measurement

• Lamination testing

• Corrosion mapping

​

Typical flaws detected when using ultrasonic inspection:

​

• Detection of manufacturing flaws (lack of sidewall fusion, lack of root penetration, lack of root fusion, porosity, etc.)

• In-service flaws (fatigue cracking, stress corrosion cracking, corrosion, erosion, etc.)

• parent material flaws (inclusions and laminations)

 

Suncoast NDT utilizes modern Olympus inspection equipment for its testing.
