Flaw Detection with Non-Destructive Testing – Protecting Your Materials and Safety

Non-Destructive Testing (NDT) is an essential quality control method used in various industries to identify material defects or irregularities in components without compromising their function or structural integrity. By applying different testing techniques, both internal and external defects can be detected at an early stage, helping to prevent production failures and minimize safety risks.

we use various NDT methods such as ultrasonic testing (UT) and magnetic particle testing (MT) to test materials for internal and external defects. These techniques can detect potential flaws or irregularities such as cracks, voids, porosity or other discontinuities without damaging the material. By using these methods, we ensure that the functionality and safety of the components are maintained.

Ultrasonic Testing (UT)
UT utilizes high-frequency sound waves to detect internal flaws such as cracks, voids, or bonding defects. The mechanical signal (sound) is reflected by conditions in the test object and analyzed for amplitude and distance from the transducer. UT is widely used for weld inspections, wall thickness measurements, and structural integrity assessments.

Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive testing (NDT) method that utilizes multiple ultrasonic elements and electronic beam steering to inspect materials for internal defects, thickness variations, and weld discontinuities. This technology provides high-resolution imaging and greater flexibility compared to conventional ultrasonic testing (UT), making it a preferred method in industries requiring precise and reliable inspections.

Magnetic Particle Testing (MT)
MT is a method used specifically for ferromagnetic materials. A magnetic field is applied to the test object, and fine iron particles (dry powder or liquid suspension) are introduced. These particles gather around leakage fields, making surface and near-surface defects visible. This method is commonly applied to high-stress components such as structural steel and aerospace parts.

Liquid Penetrant Testing (PT)
PT is used to detect surface-breaking flaws such as cracks and porosity in non-magnetic materials like stainless steel, aluminum, and ceramics. A liquid dye (fluorescent or colored) is applied to the surface and drawn into defects by capillary action. A developer is then applied to enhance visibility. PT is highly effective for detecting fine cracks in welds, castings, and machined parts.

Visual Inspection (VT)
VT is the most fundamental NDT method, involving a direct visual examination of a material’s surface to identify defects such as cracks, corrosion, or misalignments. This method is often enhanced with magnification tools, borescopes, or cameras to inspect hard-to-reach areas. VT is frequently used in weld inspection, structural assessment, and component verification.

Verification of material certificates:
we also check material certificates to ensure they meet  standards and specifications. This includes evaluating test reports from suppliers or manufacturers and verifying that material properties meet requirements for the intended application.


Reporting and documentation:
After each test, we carefully document the results and prepare detailed test reports. These reports describe the test results, defects found, the methods used and the conclusions drawn. These documents serve as evidence for quality assurance and provide a basis for possible corrective actions if necessary.

Damage assessment and failure analysis:
If damage occurs to components, we perform a damage assessment and analyze the cause of the failure. Whether the damage was caused by overload, material defects or manufacturing issues, your analysis plays a critical role in identifying the root cause. This process helps develop solutions to prevent similar damage in the future, thus ensuring reliability and safety in the long term.
