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)
PMR Inspections utilizes modern Olympus inspection equipment for its testing.
