Non Destructive Testing

Safety Assurance:

• NDT helps prevent catastrophic failures by detecting critical-size defects in materials, components, and structures.
• Engineers rely on NDT results to validate that manufactured products meet design specifications and are safe for use.

Quality Validation:

• NDT measurements serve as essential validation of product quality.
• By assessing material properties without causing damage, NDT ensures that products meet industry standards and perform as intended.

Economic Value:

• NDT adds economic value to the manufacturing process.
• Detecting defects early prevents costly rework or recalls due to poor-quality products reaching consumers.

Continuous Improvement:

• NDT measurements provide numeric parameter datasets.
• Manufacturers use these data for statistical analysis, process improvement and quality control.

Non-Destructive Testing Solutions

CIB Mars offers a comprehensive range of Non-Destructive Testing (NDT) solutions to ensure the integrity and reliability of materials, components, and assemblies without compromising their functionality. Let’s explore some of the NDT methods and solutions provided by CIB Mars:

Ultrasonic Testing (UT):

• UT transmits high-frequency sound waves into the target material to detect flaws or changes in material properties.
• The pulse-echo testing method is commonly employed, where internal flaws or surfaces reflect sound back as echoes.

Magnetic Particle Testing (MT):

• MT creates a magnetic field in ferromagnetic material and applies iron dust to the surface.
• Surface and close-to-surface imperfections affect the magnetic field, revealing their presence.

Liquid Penetrant Testing (PT):

• PT is a widely used NDT technique.
• A visible or fluorescent dye solution is applied to the test object or material.
• A developer is then applied to extract penetrants from exposed flaws.
• Visible dyes show “blued out” areas due to the colour contrast between the penetrant and developer, while fluorescent dyes are visible under UV light.

Radiographic Testing (RT):

• RT uses penetrating X-rays or gamma radiation to check for defects in parts and goods.
• Radiation is directed onto film, creating a shadowgraph during development.
• Potential flaws appear as density fluctuations on the film.

Visual Testing (VT):

• VT involves direct visual inspection of surfaces.
• Inspectors visually examine components for defects, irregularities, or anomalies.
