  Advantages and disadvantages in inspection visual

  Among the advantages of this type of non-destructive test, we can highlight:
  • It is the lowest cost non-destructive test;
  • Allows to detect and eliminate possible discontinuities before starting or completing the welding;
  • It allows the identification of major discontinuities and generally indicates possible points where discontinuities may arise, which must be inspected by other non-destructive tests;
  • A well-achieved visual inspection provides a reduction in the amount of repairs to the weld, leading to greater production of the other non-destructive tests and therefore decreasing the cost of production.

  Among the limitations and disadvantages of this type of trial we can highlight:
  • It depends a lot on the inspector’s experience, as well as on his knowledge in welding, besides the need to be inside the project and its requirements;
  • It is limited to the detection of surface defects.
