Visual inspection services (VT)
A visual inspection or visual examination of objects, parts or components is the oldest and reliable non-destructive testing method.
Visual inspection is particularly effective detecting macroscopic flaws, such as poor welds. Many welding flaws are macroscopic: crater cracking, undercutting, slag inclusion, incomplete penetration welds
Capabilities: Macroscopic surface flaws
Limitations: Small flaws are difficult to detect, no subsurface flaws.
