Non Destructive Testing (NDT)
Ultrasonic Thickness Measurement
Ultrasonic Testing (UT) is a volumetric Non-Destructive method that uses high-frequency sound waves that conduct examinations and make measurements.
Why is it used?
It is widely used in engineering applications and also in the medical field. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. It simply makes it possible to find flaws in the material.
How is it used?
The high-frequency sound waves are sent into the material with an ultrasonic transducer. Depending on the requirements, these waves can be highly directional and focused on a very thin line, or limited to a very short duration. There are certain methods that are used to detect a flaw.
- Advantages :
- The test piece does not have to be cut, sectioned, or exposed to damaging chemicals.
- High penetration power, allowing for flaw detection deep within a part.
- High sensitivity, allowing for the detection of very small flaws.
- Access to only one side is required.
- However, there are a few limitations in using the ultrasonic testing
- Requires experienced technicians for inspection and for data interpretation
- Objects that are rough, irregularly shaped, very small or thin, or not homogeneous are difficult to inspect.
Magnetic particle testing
Magnetic particle testing is also referred to as non-destructive inspection material which is used for detecting materials. It is used to detect surface and some flaws slightly subsurface flaws in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. In simple terms it is used primarily for surface flaws. This method is also applicable to all the metals.
Why is it used?
The magnetic flux should be at right angles to a flaw as this creates maximum flux leakage. It is used to produce magnetic lines of force or flux in the material. If in any case these lines of power meet a discontinuity, for example, a break, optional attractive posts are made at the essences of the break.
How magnetic particle testing?
This is used In the process of a floor or barely sub floor illness being present, the strains of magnetic pressure will deform across the illness.The magnetic ink is implemented and the iron powder debris will bridge the space due to the illness and provide a seen indication in opposition to the white comparison background.
Dye Penetrant Testing
Dye Penetrant Inspection (DPI), additionally called Liquid Penetrant Inspection (LPI) or Penetrant Testing (PT), is one of the most seasoned and simplists NDT techniques where its soonest forms (utilizing lamp fuel and oil blend) traces all the way back to the nineteenth century.
Fluid penetrant assessment is utilized to distinguish any surface-associated discontinuities like breaks from weakness, extinguishing, and pounding, just as cracks, porosity, deficient combination, and imperfections in joints
- Advantages :
- High affectability (little discontinuities can be identified).
- Hardly any material restrictions (metallic and nonmetallic, attractive and nonmagnetic, and conductive and nonconductive materials might be reviewed).
- Fast assessment of enormous territories and volumes.
- Reasonable for leaves behind complex shapes.
- Signs are delivered straightforwardly on the outside of the part and establish a visual portrayal of the blemish.
- Convenient (materials are accessible in vaporized shower jars)
- Minimal effort (materials and related gear are moderately modest)
Ultrasonic Thickness Measurement
These systems give for the sorting of fabric, supported variations in hardness, heat treatment, grain structure, case depth and material grade. Manual, semi-automatic and totally automatic (inline/offline) sorting systems ar created offered, supported the need.
What can be measured with ultrasonic thickness?
Ultrasonically measuring almost any common engineering material is possible. Metals, plastics, composites, fibreglass, ceramics, and glass can all be gauged with ultrasonic thickness gauges. Extruded plastics and rolled metal can also be measured on-line or in-process, as can individual layers or coatings in multilayer fabrications. Levels of liquid and biological samples may also be measured.
How ultrasonic thickness gages work?
Ultrasonic thickness gages work by means of very precisely measuring how long it takes for a legitimate pulse that has been generated via a small probe referred to as an ultrasonic transducer to tour through a check piece and reflect again from the interior floor or far wall. due to the fact sound waves mirror from limitations between multiple materials, this measurement is usually made from one side in a “pulse/echo” mode.
Eddy Current Material Sorting
These systems give for the sorting of fabric, supported variations in hardness, heat treatment, grain structure, case depth and material grade. Manual, semi-automatic and totally automatic (inline/offline) sorting systems ar created offered, supported the need.

Hardness testing
The application of hardness testing enables you to evaluate a material’s properties, such as strength, materials amenability and wear resistance, and so helps you determine whether a material or material treatment is suitable for the purpose you require.
HOW DO HARDNESS TESTS WORK?
A hardness test is usually performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the fabric you’re testing. The hardness is decided by measuring the depth of indenter penetration or by measuring the dimensions of the impression left by an indenter. Hardness tests that measure the depth of indenter penetration include: Rockwell, Instrumented Indentation Testing, and Ball Indentation Hardness Hardness tests that measure the dimensions of the impression left by the indenter include: Vickers, Knoop, and Brinell
