Ultrasonic Testing

Ultrasonic Testing is a Non-Destructive Testing method used for obtaining Wall Thickness Measurements to determine any erosion and/or corrosion damage and for identifying flaws including weld root erosion and fatigue cracking in welded components.  UT Inspection works for determining both internal and external defects and is an accurate measuring tool for establishing the exact location and depth of noted flaws.

These are normally applied to structures that are more often subject to corrosion, erosion, and internal defects such as laminations or inclusions.

They are also applied to welds to detect fabrication defects and when in-service to detect weld root erosion and fatigue cracks. These techniques rely on favourable orientation of the imperfections to be noted relative to the direction of the applied ultrasound. The geometry of the imperfection such as pitting is also a main consideration.
