Notch Impact Test

The notch impact test determines the material toughness with regards to the temperature. We use a pendulum machine according to DIN 51222 of the Material Testing Institute (MPA) in Dortmund, which has been inspected and approved according to DIN 10045 Part 2 for a testing range up to 300 J.

Notch Impact test according to 50115

all source materials according to DIN 50115
Weld samples according to DIN 50111 & DIN 50122

The choice of material must guarantee a sufficient impact energy for the whole applicable temperature range. For some materials the impact energy drastically drops with low temperature (starting from -10°C).

Tensile, Compression, Bending Test

With variably applicable testing machines we can conduct all static strength tests and therewith analyze the deformation and strength performance under static stress. For this puprose we use a all-purpose testing machine according to DIN 51221 of the Material Testing Institute (MPA) in Dortmund that has been inspected and approved according to DIN 51302 Part I and DIN EN 100002-2 for the testing range 4 – 200 KN in class 1.

Metallographic Inspection

The metallographic inspection identifies slightest modifications or deviations in the microstructure of the material with the aid of a microscope.

Microscopic and macroscopic inspection

[glyphicon name="ok-sign"] for welding seams according to DIN EN 1321
[glyphicon name="ok-sign"] for source material according to DIN EN 50601 and 50602

Macrodection: identification of discontinuities in the welding seam
Microsection: inspection of the structure to determine the grit size

Fractography

The fractography gives information about the kind of fracture. This way we can determine if the material has had an incipient crack prior to operations that enlarged or if the crack originated during the operation itself. Moreover we can determine if the crack is based on a fatigue fracture or forced fracture.
