Danem Test & Certificate provides non-destructive testing services to support product certification, manufacturing quality control, and project inspections. NDT helps verify the condition of components and welded assemblies without affecting their usability, making it ideal for both production and in-service assessments.
We support clients from method selection and inspection planning through execution and clear reporting. Our approach is tailored to the material, component geometry, and applicable technical requirements, helping manufacturers identify issues early and avoid costly rework or delays.
From the outset, we define the inspection scope, acceptance criteria, and required documentation to ensure a structured and predictable evaluation process.
What Is Non-Destructive Testing (NDT)?
Non-destructive testing (NDT) is a group of inspection methods used to detect defects, discontinuities, and integrity issues in materials and components without causing damage. It is commonly used to assess weld quality, surface and internal flaws, wall thickness, and material condition under defined inspection conditions.
Typical NDT methods include visual inspection (VT), penetrant testing (PT), magnetic particle testing (MT), ultrasonic testing (UT), radiographic testing (RT), and thickness measurement. NDT evidence is widely used to support certification, acceptance inspection, and ongoing quality assurance.
Typical applications include welded assemblies, metal enclosures, structural components, pressure-containing parts, pipelines, and safety-critical equipment used in regulated environments.
Non-Destructive Testing
Our NDT process is designed to provide clear, traceable results and reduce inspection uncertainty.
1. Scope definition and method selection
We review the component, material, and inspection objective to confirm the appropriate NDT method(s), coverage, and acceptance criteria.
3. NDT inspection and evaluation
Inspections are performed using the agreed method(s), with findings evaluated against the defined acceptance criteria.
2. Inspection planning and preparation
We confirm access, surface condition, inspection locations, and required documentation to ensure consistent inspection quality.
4. Reporting and technical conclusions
We issue clear inspection reports, including findings, locations, and conclusions suitable for certification support, QC release, or project documentation.
Need Clear Inspection Evidence?
Define the right NDT method, acceptance criteria, and documentation — aligned with your certification or project requirements.
Which NDT method should we choose for our product or welds?
The best method depends on material type, thickness, geometry, and the defect types of concern. We help confirm the most appropriate method during scope definition to avoid unnecessary inspections.
What information is needed before an NDT inspection starts?
Typically, drawings, weld maps (if applicable), material details, inspection areas, acceptance criteria, and access conditions. Photos and clear identification of inspection zones help speed up planning.
Can NDT be performed on finished products without disassembly?
Often yes, provided access to inspection areas is available and the surface condition is suitable. The final approach depends on geometry, coating, and inspection objectives.
How are NDT findings documented for certification or project acceptance?
Results are recorded in structured inspection reports showing method, coverage, findings, and evaluation against acceptance criteria. Reports can be aligned to project or certification documentation needs.
Can NDT be used together with destructive testing?
Yes. NDT is often used for screening and routine quality control, while destructive testing may be used for validation, investigation, or qualification. The combined approach depends on the standard and project requirements.
