Vinçotte (member of Kiwa Group) is the specialist in Belgium for (advanced) Non-Destructive Testing (NDT). Vinçotte offers various ultrasonic examination techniques, including Phased Array testing. Phased Array is one of our specialities, allowing us to examine welds to ensure their quality and longevity.

What you need to know

Phased Array is an ultrasonic examination technique that utilizes probe technology. By incorporating multiple crystals in one housing, an ultrasonic beam can be created. The generation of the sound beam(s) is achieved by timing the activation of the different crystals using advanced ultrasonic equipment. The shape, angle, focusing, and intensity of the beam can be varied within certain limits. This enables us to 'focus' the sound waves on specific zones within the object being examined.

Phased Array utilizes reflection and shares the same properties as ultrasonic weld testing. During the examination, one or more probes are generally moved parallel along the weld seam within a frame at a certain distance from the weld. Phased Array weld testing can be applied to welds of various steel types and plastics. The minimum wall thickness for carbon steel is 3.2 mm. There is no real upper limit for wall thickness in this examination. The minimum diameter is 33 mm (1 inch). For Phased Array testing, it is necessary to have sufficient clearance on at least one side of the weld to examine the weld volume. If possible, the weld should be examined from both sides.

The quality of materials and connections is essential for the safety and reliability of installations and products. All manufacturers must be able to guarantee the safety and lifespan of their products before they are released onto the market.
