Non-Destructive Material Testing

Zeros GmbH combines all important procedures of non-destructive material testing (NDT) – from weld seam testing to component approvals and series testing. We test mobile in manufacturing or stationary in the testing laboratory and deliver comprehensible results with clear statements on component quality.

• Accredited testing laboratory according to DIN EN ISO/IEC 17025
• All core procedures in-house: UT, RT, MT, PT, VT & Phased Array
• Testing of weld seams, cast parts, forged pieces, pipes, semi-finished products
• Series and single testing, inline or offline
• Digital test reports and audit-proof documentation

• Weld seam testing in steel construction, plant and pipeline construction
• Quality controls on cast parts, forged pieces and semi-finished products
• Incoming goods inspection and supplier approvals
• Series testing with automated processes
• Maintenance, railway and power plant inspections

• Ultrasonic Testing (UT) – detect volume defects, measure wall thickness; incl. Phased Array and TOFD.
• Radiographic / X-ray Testing (RT) – digital/analog radiography for volume defects, component approvals, documentation.
• Magnetic Particle Testing (MT) – surface and near-surface defects on ferromagnetic materials.
• Dye Penetrant Testing (PT) – finest surface cracks on metallic and non-porous materials.
• Visual Testing (VT) – qualified visual assessment, often the first step in the testing process.
• Phased Array – imaging UT technology for complex geometries and weld seams.
• Crack Testing – overview & selection of the appropriate method (MT/PT/UT) for your application.

We work according to current DIN EN / ISO standards as well as customer-specific specifications. Testing and documentation are designed to legally fulfill your quality, audit, and approval requirements.
