Non-Destructive
Testing Methods

We provide comprehensive insights and precise analyses.

Visual Inspection

Optical inspection of welded joints, castings, or forgings for visible defects such as cracks or surface flaws.

Video Endoscopy

Visual inspection in hard-to-reach areas using a flexible cable with an integrated camera.

Magnetic Particle Testing

Magnetizable materials are tested with magnetic particles to reveal cracks and inclusions.

Penetrant Testing

A colored or fluorescent penetrant highlights surface defects such as pores or cracks.

Leak Testing

Vacuum testing verifies absolute tightness of components and detects even smallest leaks.

Radiographic Testing

Gamma or X-rays identify internal irregularities such as cracks, pores, or inclusions.

Ultrasonic Testing

Sound waves detect internal defects such as cracks and bonding errors with high precision.

Ultrasonic Phased Array Testing

Advanced ultrasonic method for detecting inhomogeneities in simple and complex geometries.

Ultrasonic Wall Thickness Measurement

Determines wall thickness in pipelines, vessels, and tanks with one-side accessibility.

Hardness Testing

Measures material resistance to indentation and supports quality assessment of mechanical properties.

Spectral Analysis

Analyzes the light spectrum of materials to verify chemical composition and detect alloy errors.
