Visual Testing

The Principle Behind Visual Inspection

The essential first step in any quality testing procedure. Often overlooked, visual inspection provides a critical foundation for identifying surface defects before further testing begins. We also offer it as a standalone service for clients who need fast, reliable assessment.

Direct Observation

Trained technicians examine components using human senses – primarily sight, but also touch and hearing where appropriate – to identify visible defects.

Defect Identification

Surface flaws such as cracks, corrosion, misalignment and wear are detected with a high degree of accuracy, determining whether further NDT methods are required.

Non-Destructive Testing (NDT) refers to a range of inspection techniques used to evaluate the integrity, quality, or properties of materials and components without causing damage. This allows assets to remain in service while ensuring safety and compliance.
NDT is widely used across many industries, including:
  • Oil & Gas
  • Construction & Infrastructure
  • Manufacturing
  • Aerospace & Automotive
  • Power Generation
  • Marine & Offshore

Any industry where safety, reliability, and compliance are critical can benefit from NDT.

We offer a range of NDT techniques, including:
  • Ultrasonic Testing (UT)
  • Radiographic Testing (Film & Digital)
  • Magnetic Particle Inspection (MPI)
  • Dye Penetrant Inspection (DPI)
  • Visual Inspection (VT)
  • Eddy Current Testing (ECT)
  • and more….

Our team can advise on the most suitable method for your application.

The appropriate method depends on factors such as:
  • Material type
  • Component geometry
  • Defect type being investigated
  • Industry standards and regulations

Our certified technicians will assess your requirements and recommend the most effective and cost-efficient solution.
