Ultrasonic Testing (UT) on welds

Ultrasonic Testing (UT) on welds is a proven non-destructive testing (NDT) method used to detect internal flaws and assess the quality of welded joints. At Cspect, we rely on portable flaw detectors to inspect welds accurately and efficiently across a wide range of assets – including ship hulls, tanks, and structural components.

Using high-frequency sound waves, this technique allows us to identify hidden issues such as cracks, lack of fusion, or porosity – without damaging the material. It can be applied to a variety of metals like steel, stainless steel, aluminium, and even painted or corroded surfaces.

The image shows a Cspect technician using a flaw detector to inspect a weld seam on a vessel's hull. After preparing the surface, the ultrasonic probe is placed to transmit and receive sound waves, making internal defects visible through a clear A-scan display.

UT on welds is essential for verifying weld integrity, ensuring compliance with standards, and preventing costly failures – especially in safety-critical applications.
