Time of Flight

  • Can be applied to new construction welds, in lieu of radiography (ASME Code Case 2235), providing an excellent record of vessel or pipe condition at birth.
  • Can also be used for in-service defects, such as cracking, corrosion, erosion, etc. Has a very high temperature limitation (700 F), with slight loss in sensitivity.
  • Detects flaws regardless of their orientation within the weld.
  • Can be applied without the need to shut down other activities in the area (which RT demands).
  • Can be applied either during welding or immediately after completion of the weld, allowing instant determination of weld quality.
  • Allows flaw growth monitoring for run/repair decisions.
