Training Ultrasonic

General Information:


Ultrasonic examination (UT) is an NDO method by which sound waves are directed into a material. These will be reflected by any defects and/or the geometry of the object. By recording the reflected waves, (weld) defects can be detected.

General

Before starting the examination, the surface must be cleaned: coating, welding spatter, grease and dirt should be removed. For the determination of the residual wall thickness, in most cases the coating may remain.

Inaudible sound waves will be introduced into the object by means of a sound generator (probe/transducer). These sound waves will be reflected at the location of a defect or geometry. When the sound waves come back to the probe they will be detected, this is called a reflector. In the probe, the received sound will be transformed into an electric signal. Which will be displayed on a screen. The position, shape and height of the signal on the screen will be interpreted by the operator. The assessment will be made on the basis of the required standard and/or specification. The reflector shall be assessed in accordance with the required standard, resulting in acceptable or unacceptable (in case of wall thickness measurement, the wall thickness will be reported).

Ultrasonic testing can be done using different types of probes. A distinction is made between straight and angled probes. In case of angled probes, the generated sound will be directed into the material at a certain angle, whereas for the straight probes the generated sound will be directed into the material perpendicular to the surface. Both groups of probes can be fitted with a combined transmitter and receiver or with separate transmitter and receiver (SE or TR probe).

The most common testing is carried out by transmitting the sound and absorbing the reflection (pulse echo). It is also possible to irradiate an object, in which case transmitter and receiver are (must be) placed on opposing sides of the object. For each application, the best probe choice must be made in order to perform an optimal test.

If the operator has detailed knowledge of the object, knows the manufacturing process and/or is familiar with the conditions of use, this will have a positive effect on the ultrasonic test.

Scope/Products/Sectors

Ultrasonic testing of objects made of various materials for surface and internal defects, (de-) laminations, (fatigue) cracks, determination of (wall) thickness and/or welding defects.

The testing has many application possibilities, but is specifically applied to the following products:

  • Cast and forged parts made of aluminium, steel and brass;
  • Weld joints of materials with a homogeneous fine structure;
  • Plate material of aircraft hull and industrial semi-finished products;
  • (Wall) thickness determination in petrochemistry, shipbuilding, aircraft construction and/or food industry;
  • De-laminations and deformations in composite parts occurring in aircraft construction, petrochemistry, shipbuilding, windmills, water/gas pipelines and automotive industry;
