Visual Inspections
Visual Testing is based on the inspection for flaws that are visible to the naked eye and is the most commonly used NDT method across all industries. It allows for a feasible and fast control of quality at every step of the fabrication or maintenance process.
Visual Testing (VT) is used to detect visible flaws such as deformation, welding defects and corrosion. Many tools can be used during the inspection such as a ruler, gauges, cameras, etc.
Advantages:
- Reduction in repair costs because of constant monitoring at every step of fabrication;
- Understanding of different degradation phenomena;
- Documentation of the observations using measurement tools;
- Very cost efficient and quick QC/QA technique.
Drone Inspections
Additional Information
New available technologies as "drone-based visual inspection" with a collision safety can be deployed in confined spaces or inaccessible areas. A team composed of an inspector and a drone pilot conduct the inspection from a safe location enabled by a powerful lighting system, a 4k video camera and a thermal camera which is installed on the drone.
Advantages:
- Takes human operators out of risk;
- Greatly reduced costs by avoiding scaffolding or confined space entries;
- Greatly reduced (or even eliminated) downtime;
- Increased inspection speed;
- Flexible and versatile data.
