Inspections - High-end inspections

We offer a wide range of tests and inspections, starting from non-destructive testing methods (NDT) optical precision measurement and dye-penetrant tests as well as chemical analysis and classical inspections, e.g. tensile test, notch impact test, hardness tests and many more.

Testing methods we offer:

Chemical analyses:

• Alloy determination by optical emission spectrometer (stationary) for Cu- , Al- and Fe-based alloys
• Mix-up testing (mobile) by X-ray fluorescence analysis

Non-destructive material testing:

• Dye penetrant testing
• Ultrasonic testing
• X-ray inspection
• Surface roughness test
• Visual inspection

Destructive material testing:

• Tensile test
  
• Notched-bar impact test
• Hardness tests according to Brinell (stationary, mobile), Rockwell (mobile) and Vickers (mobile)

Component inspection:

• Optical 3D measurements (stationary, mobile on request) by photogrammetry and fringe projection
• Pressure tightness test
• Helium leakage test

Determination of material characteristics:

• Thermal conductivity
• Electrical conductivity
• Corrosion behaviour
• Attenuation test

Foundry-specific testing technologies:

• Various molding material testing methods (strength, moisture, gas permeability, sieve analysis)
• Hydrogen measurement (carrier gas hot extraction)
  
• Various temperature measurement methods

Specific quality tests:

• Static unbalance testing of propellers and other rotationally symmetric objects up to a mass of 150t
• Testing the fit of tapered elements, e.g. propeller shafts, using male gauges (blue fitting test) or optical measuring method (VCT)
• Mobile metallography
