Laboratory Expertise

Our labs provide services to external and in-house customers such as quality assurance, application engineering, contract testing and research and development. Modern machines and well trained employees are the key to reliable results.

Quality assurance, testing and the development of newly developed filler metals must be carried out in certified testing labs. Specific customer requirements are met by the modern and well-equipped labs of voestalpine Böhler Welding. Our welding labs are indispensable in the testing of newly developed filler metals. Such metals are also tested during the development phase in order to determine product properties and levels of quality. Test welds are performed additionally for the purpose of acceptance tests. Special analyses are particularly necessary for high-alloyed and medium-alloyed filler materials and can only be conducted using modern equipment such as that in the chemistry lab of voestalpine Böhler Welding Germany. Regular and successful participation in international round-robin tests document our comprehensive expertise. The chemistry lab of voestalpine Böhler Welding Germany has been certified since 2012 according to internationally recognized DIN EN ISO/IEC 17025 (D-PL-17123-01-00). In order to meet the requirements of pertinent standards and regulations, filler materials must be tested for their mechanical suitability. Our material testing labs provide a wide spectrum of non-destructive, mechanical and metallographical tests. If required, testing can be performed in the presence of an independent certification institution and/or the customer.
