In our in-house laboratory, our specially trained experts ensure optimal quality of materials in accordance with international standards. In addition to Strength and Charpy impact tests, hardness testing and chemical analyses, the properties of materials - such as the microstructure, intergranular corrosion and degree of purity - are also examined from a metallographic perspective.
Non-destructing testing are essential for quality control and quality assurance. Specially trained employees at WSK conduct ultrasonic testing (UT), magnetic particle testing (MT), penetrant testing (PT) and visual testing (VT), which are certified in accordance with levels 1, 2 and 3 of DIN EN ISO 9712. For this testing we use the most precise technologies. Our magnetic particle testing facility is one of the largest in the world. It enables us to conduct a combined inspection (current linkage and field linkage) as a single process. Our ultrasonics allow us to investigate the tiniest of material defects (circular disc-shaped reflector measuring 0.3 mm or more).

Experienced WSK employees not only visually inspect all products before they leave the plant. All products also undergo a dimensional check which is consistently monitored by accredited partners.
At the customer's request every product can be supplied with an inspection certificate in accordance with EN 10204.
