X-ray fluorescence analysis (XRF), also known as X-ray fluorescence spectroscopy (RFS), is a method from the field of material analysis.
XRF is one of the most frequently used methods for the qualitative and quantitative determination of the elemental composition of a sample, because the samples are not destroyed by the measurement.
At Güldner, this method is used to check every incoming raw material sample for mix-ups and to document the results in a traceable way.
Upon customer request, this method is also used for testing the finished fasteners.
The Penetrant Test (PT) is a non-destructive test method for the visual detection of surface cracks. The method is used for non-magnetizable steels (e.g. austenitic steels), among others.
Due to chemical-physical properties (capillary effect), a liquid (penetrant) applied to the residue-free cleaned surface of the test object penetrates into the defective surface areas. After intermediate cleaning of the test surface, this penetrant is made visible by a so-called developer (usually white powder) as a contrast background. Red dye penetrants are often used, which produce red indications on a white background ("red/white testing"). By using fluorescent penetrants in combination with UV radiation, the contrast of a display can be significantly enhanced.
The Magnetic Particle Test (MT) is used for the detection of surface defects (cracks) in ferritic materials (mainly steel). The method has the advantage of a very high sensitivity for the detection of surface defects.
By using different magnetization techniques, a magnetic field is applied to the workpiece to be tested. Close to and in the surface of the workpiece, where the magnetic properties (relative permeability) of the material change significantly (e.g. cracks), the magnetic field emerges from the surface as magnetic leakage flux. This effect can be visualized by colored (usually black or fluorescent) magnetizable particles (magnetic powder), which are applied to the test object during the test.
Compared to other non-destructive testing methods, magnetic particle testing can be safely used even with complicated material geometry and unmachined surfaces.
We carry out tensile tests according to standard or your specifications. Our machine has a tensile force of 600 KN (60 tons).
All results are electronically recorded and archived.
The machine is additionally equipped with a strain gauge. This allows all relevant mechanical values to be determined.
Güldner offers you complete traceability as standard for articles ordered with an inspection certificate from the finished component to the raw material. The documentation in the individual production steps can also be traced at any time. For articles ordered without an acceptance test certificate, we can separate individual production batches from each other via the internal batch generated by the system.
With each goods entry in our finished parts warehouse, the system generates a unique works number, which is printed on the delivery documents, any inspection certificate and the label of the article packaging. This enables you to always clearly associate our goods with the accompanying documents.
