NDT Ultrasonic Flaw Detector

Tiny cracks and invisible material deterioration pose an existential threat to industries where integrity is essential. Aerospace components, pressure vessels, petrochemical pipelines and railroad systems all face a similar threat: subsurface defects that are may caused in the process of production or usage.YUSHI's independently developed YUT series of Ultrasonic Flaw Detectors can be used to detect defects within a wide range of metallic materials. The large colorful LED screen with high resolution and easy-to-use operation methods allow inspectors to locate defects clearly and quickly.

Key Features 

Rugged casing: designed for on-site environments

Full-screen display function: the amplitude signal area covers the entire screen

Bulk memory: up to 1,000 test data can be stored

Measures substrate thickness directly through the coating without the need for zero-point calibration

Peak memory function: the highest defect echoes can be recorded

Auto gain: automatically adjusts the amplitude of the waveform to the height of the completed setup

Colorful LCD Screen: true-colour with adjustable brightness TFT LCD display with adjustable brightness

Variable Square Wave Technology: Adjust voltage and pulse width for optimum probe selection.

YUSHI YUT-2600 Series and YUT-2800 Series are designed for most real inspection environments. YUSHI flaw detector is equipped with a stand and strap for outdoor inspection work; the instrument's case is robust, drop-proof and waterproof, and each instrument can be equipped with factory certificate, allowing users in any inspection environment to have confidence in the instrument's performance and durability.

Keypad of the Ultrasonic Flaw Detectors

The keyboard plays an intermediary role in the human-computer dialogue. The keyboard is printed in English and its layout is shown as below. All control commands issued by the user to the flaw detector are completely completed by the keyboard. During the operation of the keyboard, the instrument is able to recognise the various meanings of each key according to different conditions, and then execute the operator's commands. The specific usage of each key will be described in the following sections.

1.Bubbles: The steel solution contains too much gas, and the gas released during solidification remains in the steel; Due to poor degassing of dissolved steel, the forging temperature is too low; Caused by improper casting methods, etc.

2.Shrinkage porosity (or tube shrinkage): The cavity caused by the solidification and contraction of the upper end or inside the steel ingot. It is easy to occur when high temperature, high-speed pouring or poor mold design, and when the shrinkage porosity is serious and has a large length, it is also called shrinkage.

3.Trachoma: Mixture of solution and refractory material. Refractory substances are mixed into the dissolved steel and remain in the steel.

4.Deflection: Coarse corrosion on the steel section. When the steel is solidified, it is caused by the difference between the parts due to imbalance, or there are too many impurities in the molten metal, the casting temperature is too high, the speed is too slow, or the ingot mold is improper.

5.Porosity: A manifestation of the porosity or non-compactness of solid metals. When the gases and inclusions in the metal solidify on the surface of the molten metal, the inter-product void or tissue gap caused by volume shrinkage or gas floating, which is not filled by the molten metal.

6.Non-metallic inclusions: mainly various oxides or other forms of disappearance present in steel. Due to the presence of insoluble substances (such as the dissolution of fire-attached bricks) in the smelting process.

7.White spots: Rough tissues that show microcracks, generally round to form an oval silvery-white wave. There is a large amount of hydrogen in the steel, which does not have time to escape during cooling or is caused by tissue transition stress, deformation stress, and cooling stress.

8.Center forging cracks: Microcracks (cracks) that occur in the center of the steel. Unreasonable deformation or internal stress due to low temperature or uneven heating, or too high processing pressure.

9.Residual porosity cracks: Severe crater cracks in the ingot, which are not completely removed, caused by forging.

● The firm and durable instrument shell is specially designed for the hostile site environment.

● 31 copper screw nuts are inlaid in the hard plastic casing

● Innovative rotating positioning bracket is easy to use.

● The hand strap can be installed for both hands so that you can hold the machine with your left or right hand.

● The D-shaped ring on the instrument is convenient for installing a cheststrap.

● The corrosive texture of the shell surface is scratch-resistant and beautiful.

● Innovative high power lithium batteries of notebook style.

Full screen function, the echo display area can cover the entire screen, which provide you with the sense of the maximum window

Solid waveform display, the visual contrast of waveforms is increased so the undetection is hard to happen when fast scan is carried out

Bulk storage, up to 1000 data sets can be stored, including waveforms, curves, and parameters (containing the traditional 1000 channels)

Echo-echo thickness measurement, zero calibration is avoided, and the net thickness of the base material can be directly measured through the coating

Two operation interfaces are available:Chinese and English

Easy to use, the user can master the operation method very fast.
