NDT – METHODS – SECURITY AND GUARANTEE FOR YOUR BUSINESS
We use a number of NDT methods to examine components with regard to quality and capacitance.of metals, Our full range of state of the art equipment means that our engineering office is ideally positioned to employ all testing methods.
LIQUID PENETRANT TESTING (PT)
Liquid penetrant testing is a process in which a dye penetrant (often red) is applied to the surface which is to be inspected.
The dye penetrant can, through the so-called capillary force, enter the imperfections which are open to the surface.
After a certain time the excess liquid dye is removed. In the last step of the process a contrasting agent (developer) is applied to the area which is to be inspected for defects. The inspection takes place during and after the drying of the developer.
MAGNETIC PARTICLE TESTING (MT)
A hand-held yoke can be used to detect cracks which run diagonal to the connecting line between the two poles. Magnetisation produces magnetic flux lines which run parallel to the surface inside the component. Cracks lying diagonal to these magnetic flux lines disrupt/interfere with the lines and thus produce a magnetic leakage field. When ferrous iron particles are applied, the particles will collect at the defect as they are attracted by the thus created magnetic poles. Magnetic particle testing enables proof of defects close to the surface such as discontinuities, cracks, laps and folds on ferromagnetic components.
ULTRASONIC TESTING (UT)
When an ultrasonic sound wave hits an interface, a part of the wave is reflected depending on the characteristics of the adjacent medium, In case of transition from steel to air almost 100 per cent of the ultrasonic waves are reflected. This process is therefore suited to detect air-pockets like bubbles, pores, cracks or similar defects in components.
RADIOGRAPHIC TESTING (RT)
The applied radiation is weakened during penetration. This effect is used to detect cracks, pores, discontinuities and other flaws in the material. The X-ray film changes colour depending on the intensity of the radiation to which it is exposed. The higher the dose of radiation, the darker the x-ray film becomes.
VISUAL TESTING (VT)
Visually detectable defects or deviations from specifications can be identified by means of visual inspection. This process is particularly suited to detect defects like overlaps, cracks, folds, pores, discontinuities, bubbles, profile and geometric deviations, etc.
EDDY CURRENT TESTING (ET)
In the eddy current inspection alternating current flows through a conductor called probe and creates an eddy current in a conductive component. This creates an inherent secondary magnetic field which opposes the primary magnetic field. A measuring coil is used to gauge the resulting variation in the complex electrical resistance of the probe and the test object (impedance) produces a measurable variable. This procedure is suitable for the detection of imperfections which are on or close to the surface of electrically conductive components. It can, however, not be used for a general detection of imperfections or flaws. It is essential to know what type of imperfection one is looking for. Furthermore, an adjusting device with a reference flaw is necessary for the eddy current inspection.
