Ultrasonik Kusur Dedektörü
Ultrasonic flaw detectors (UT) utilize high-frequency sound waves to penetrate materials and detect internal flaws. They are commonly used for inspecting metals, composites, plastics, and welds, offering fast and precise defect detection. These devices measure the time it takes for sound waves to reflect from discontinuities within a material, making them ideal for identifying hidden cracks, voids, or inclusions.

Magnetic yoke flaw detectors use magnetic fields to detect surface and near-surface defects in ferromagnetic materials such as steel and iron. When the magnetic yoke is placed on the material, defects like cracks and discontinuities disrupt the magnetic field, revealing imperfections through magnetic particles applied to the surface.

X-ışını Kusur Dedektörü
X-ray flaw detectors use penetrating X-rays to inspect the internal structure of materials. They are highly effective for detecting internal flaws that are not visible through other testing methods, such as porosity, shrinkage cavities, and inclusions. X-ray detectors are particularly useful for components that cannot be inspected destructively, such as complex machinery and welds.

Flaw Detector FAQ
1. What is a flaw detector?
A flaw detector is a non-destructive testing (NDT) device used to detect surface and internal defects in materials or components. These defects could include cracks, voids, porosity, or inclusions, which can compromise the integrity of the material.
2. How does an ultrasonic flaw detector work?
An ultrasonic flaw detector sends high-frequency sound waves into a material. The waves reflect off internal flaws or surfaces, and the device interprets these echoes to detect defects such as cracks or voids, even if they are deep within the material.
3. What are the advantages of a magnetic yoke flaw detector?
Magnetic yoke flaw detectors are easy to use, lightweight, and affordable. They are ideal for detecting surface and shallow subsurface defects in ferromagnetic materials such as steel. This method is commonly used for inspecting welds, pipelines, and railway tracks.

The selection depends on factors like the type of material, inspection depth, portability needs, and budget.
- Ultrasonic detectors: Best for internal flaws.
- Magnetic yoke detectors: Ideal for surface inspections of ferromagnetic materials.
- X-ray detectors: Suitable for precise internal imaging in critical components.
6. Is flaw detection safe?
Ultrasonic and magnetic yoke detectors are completely safe for frequent use. However, X-ray detectors require safety protocols to protect against radiation exposure, including shielding and trained operators.
