- Visual Testing (VT) 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
