Magnetic particle examination (MT) is a very popular, low-cost method to perform in ferromagnetic material. materials that can be magnetized or strongly attracted by a magnetic field.” MT is an NDE method that checks for surface discontinuities but can also reveal discontinuities slightly below the surface.
Portable hardness testers are especially useful for immovable equipment that cannot be brought to a testing lab or have samples cut off. They can measure hardness directly on a manufactured detail and in hard-to-reach places.
A spring-loaded impact body is thrust to the test surface, effecting rebound. The speed of both the initial thrust and the rebound is measured in a non-contact mode.
Industries that use portable hardness testing
The hardness test is used for macro hardness tests, which are generally defined as tests that use indentation loads below or equal to 1 kg. Therefore, a ground surface is usually sufficient, and sometimes no preparation is required.
A roughness tester is used to quickly and accurately determine the surface texture or surface roughness of a material. A roughness tester shows the measured roughness depth (Rz) as well as the mean roughness value (Ra) in micrometres or microns (µm).
With a contact-type roughness meter, surface roughness is measured by tracing the probe across the surface of the target. In contrast, a laser- based non-contact roughness meter emits a laser beam onto the target and detects the reflected light to measure the roughness.
RA values most commonly measure different surface roughness levels. A surface roughness chart can show different types of surface finish with Ra roughness values ranging from 12.5 μm Ra (very rough) to 0.4 μm Ra (very smooth)
The basic principle of ultrasonic testing is the use of sound to inspect a material's thickness at different points. Ultrasonic thickness measurements can help inspectors find defects such as tiny cracks, gaps, corrosion, or other flaws in materials that are too minute to be seen by other NDT methods.
In this ultrasonic thickness gauge pulses are reflected by the probe when they are in contact with an object's material through its surface. Once the pulses are reflected, the thickness of an object can be measured.

An ultrasonic flow meter uses acoustic sounds to measure flow. An ultrasonic flow meter measures the flow of a liquid or gas by sending ultrasonic waves across a pipe, containing the flow in the direction of the flow and in the opposite direction of the flow. The ultrasonic waves and the velocity of the flow of the liquid or gas can be combined to determine the flow rate. An ultrasonic flow meter has two transmitters, and two receivers, with one of each mounted on either side of the pipe at a calculated distance to provide accurate readings.
PHASED ARRAY ULTRASONIC TECHNIQUE Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive examination technique that utilizes a set of ultrasonic testing (UT) probes made up of numerous small elements, each of which is pulsed individually with computer-calculated timing. This technique can be used to inspect more complex geometries that are difficult and much slower to inspect with single probes. PAUT can be used to inspect almost any material where traditional UT methods have been utilized, and is often used for weld inspections and crack detection Compared to other forms of UT, PAUT has several advantages. PAUT can be conducted more quickly than other forms of UT, often within a fraction of a second. It can easily be used for repeat scans because it has a high degree of repeatability. By emitting beams of multiple different angles sequentially, PAUT is able to create detailed and accurate cross-sections of a part. It is also particularly useful in situations where there is less room for mechanical scanning because it's able to sweep the beam without moving the probe.

TOFD is usually performed using longitudinal waves as the primary detection method. Ultrasonic sensors are placed on each side of the weld. One sensor sends the ultrasonic beam into the material and the other sensor receives reflected and diffracted ultrasound from anomalies and geometric reflectors. TOFD provides a wide area of coverage with a single beam by exploiting ultrasonic beam spread theory inside the wedge and the inspected material. When the beam comes in contact with the tip of a flaw, or crack, diffracted energy is cast in all directions. Measuring the time of flight of the diffracted beams enables accurate and reliable flaw detection and sizing, even if the crack is off-oriented to the initial beam direction. During typical TOFD inspections, A-scans are collected and used to create B-scan (side view) images of the weld. Analysis is done on the acquisition unit or in post-analysis software, positioning cursors to measure the length and through-wall height of flaws.TOFD offers rapid weld inspection with excellent flaw detection and sizing capacities. The diffraction technique provides critical sizing capability with relative indifference to bevel angle or flaw orientation. TOFD can be utilized on its own or in conjunction with other NDT techniques.
