Certified materials testing and quality assurance

From non-destructive surface testing to destructive microstructural analyses

Reliability without material loss

Our non-destructive testing (NDT) methods, which comply with international standards, guarantee a high level of reliability without damaging your workpieces. We conduct rigorous testing in accordance with a wide range of implementing standards to ensure compliance with the required quality levels as specified by EN ISO, ASME, and AWS.

Uncover imperfections and defects

  • Visual testing (VT): Our qualified and certified team conducts a visual inspection of your weld seams to ensure compliance with the relevant standards
  • Penetrant testing (PT) and magnetic particle testing (MT): Pinpoints the finest surface defects and material separations that are invisible to the naked eye
  • Positive material identification (PMI): Identifies materials using optical emission spectroscopy (OES) and X-ray fluorescence analysis (XRF) to verify the alloy composition

Radiography and ultrasound

  • X-ray inspection (RT): Images internal defects such as pores, slag inclusions, or insufficient penetration
  • Ultrasonic testing (UT): High-precision detection and evaluation of bonding defects and cracks inside the component

Scientifically verified load capacity

Give your quality assurance a sound factual basis with our destructive
testing methods for process tests and in-depth material analyses.

Broken material in testing machine
Our macro and microsection imaging techniques reveal the internal structure of the weld seam. Based on our in-depth metallurgical expertise, we analyze the heat-affected zone (HAZ) and evaluate the microstructure (e.g., ferrite content or grain size).

Hardness, tensile strength, and toughness

  • Hardness testing (HT): Monitors hardening or softening using precise hardening characteristics according to Vickers, Brinell, and Rockwell
  • Tensile and bending testing: Determines the structural strength and deformability of your welded joints
  • Notched bar impact test (Charpy): Tests toughness and brittle fracture behavior—essential for applications in the low-temperature range as low as -60 °C (e.g., in bridge construction, transportation, and plant engineering).
