 | Visual inspection is performed on welds, rivets & bolts by means of unaided visual tools e.g: human eye and means of aiding tools to increase sensitivity and accessibility e.g: welding gages, mirrors, magnifiers, borescopes etc. to evaluate corrosion, loose bolting elements, surface cracks, weld visual condition and more. |
| Radiography or Ultrasonic if permitted by the applicable standard to detect internal welding defects as cracks, lack of penetration, porosity, undercutting etc. |
| Magnetic Particle inspection on welds and other steel members to detect surface or slightly subsurface cracks. |
| Poisson's ratio Determination to evaluate the mechanical properties of the steel and fire damage. |
