Ultrasonic Weld Inspection

Ultrasonic Testing (UT)

Ultrasonic Testing (UT) is a sub-surface non-destructive inspection method used to assess the integrity and soundness of the weldment, Heat Affected Zone (HAZ), and parent material. This ensures that components are free from internal defects and fit for their intended service.

UT works by transmitting high-frequency sound waves into the material. Both shear waves and longitudinal waves are used to penetrate the component and detect internal discontinuities, such as lack of fusion, inclusions, porosity, or cracking.

At WHE NDT, our qualified and experienced Ultrasonic Testing engineers carry out inspections to the highest standards and provide clear, detailed reports explaining all findings and results.
