Non-destructive testing & quality assurance
QsD tests welds, castings and structures without damaging them, and documents the results clearly, so you can make sound decisions about safety and quality.
QsD Qualitätssicherung und Dienstleistungen GmbH is a service company for non-destructive testing and quality assurance, based in Weener in Lower Saxony.
We examine materials and joints without cutting, loading or altering them. Our reports describe what was tested, how, and what was found, in plain language that engineers, site managers and auditors can all work with.
We work with manufacturers, fabricators and operators who need dependable inspection alongside their own production and maintenance schedules.
Each method suits different materials and defect types. We help you choose the one that fits the component and the standard it must meet.
High-frequency sound waves reveal internal flaws such as cracks, lack of fusion and inclusions, and measure wall thickness. Well suited to welds, plates, forgings and pipework.
X-ray or gamma imaging records the internal structure of welds and castings on a permanent image.
Reveals surface and near-surface cracks in ferromagnetic materials through magnetic field disturbance.
Dye penetrant makes fine surface-breaking defects visible on metals, ceramics and other non-porous materials.
Structured visual and remote inspection, documented with measurements and photographs.
Inspection plans, test procedures and documentation that support audits and customer requirements.
We recommend the technique that suits your material, geometry and applicable standard, not the one that is easiest for us.
One-off inspections or recurring programmes, planned around your production and maintenance windows.
Reports state scope, method, equipment and findings in a structured format that is easy to review and archive.
Careful preparation, calibrated procedures and a second look at anything unclear before a result is issued.
Tell us what you need to test and which standard applies. We will reply with questions or a proposal.
