Time of Flight Diffraction (TOFD)
Time of Flight Diffraction (TOFD) is delivered to detect, locate and characterise relevant discontinuities or degradation using a technique appropriate to the examination objective. IAIS UAE develops the scope around the equipment design, materials, service environment, operating history, expected damage mechanisms and the client’s required decision. This prevents technique-led inspection from becoming disconnected from asset risk and ensures that findings are traceable, technically relevant and suitable for maintenance or engineering review.
Service Overview
Time of Flight Diffraction (TOFD)
Time of Flight Diffraction (TOFD) is delivered to detect, locate and characterise relevant discontinuities or degradation using a technique appropriate to the examination objective. IAIS UAE develops the scope around the equipment design, materials, service environment, operating history, expected damage mechanisms and the client’s required decision. This prevents technique-led inspection from becoming disconnected from asset risk and ensures that findings are traceable, technically relevant and suitable for maintenance or engineering review.
Category context:
This category provides conventional and advanced nondestructive examination for detecting, locating, sizing and monitoring discontinuities without unnecessarily damaging the component. IAIS UAE selects methods according to material, geometry, thickness, accessibility, surface condition, expected defect orientation and the technical decision required. Conventional techniques establish broad quality and condition information, while advanced ultrasonic, electromagnetic, radiographic and monitoring methods can provide improved coverage, imaging or screening for complex assets.
Integrity Context
Key considerations for this service category
Integrity consideration
Complex geometry, restricted access, coatings, insulation, elevated temperature or operating constraints that reduce examination effectiveness.
Integrity consideration
Differentiating screening indications from confirmed reportable conditions and choosing suitable complementary methods.
Integrity consideration
Producing traceable data that can be repeated, compared and used by inspection, quality and engineering teams.
Category Delivery
How IAIS UAE approaches the work
The service normally includes review of drawings and acceptance requirements, technique selection, procedure or scan-plan preparation, reference or calibration setup, controlled data acquisition, quality verification and evaluation by appropriately qualified personnel. Where required, IAIS UAE may combine VT, UT, PAUT, TOFD, FMC/TFM, radiography, surface methods, PEC, guided waves, PMI, hardness, metallography, acoustic emission or leak testing to address different degradation mechanisms and coverage limitations.
Typical assets
Welds, plates, forgings, castings, pipes, vessels, tanks, structural members, pressure components, insulated equipment and fabricated assemblies.
Client value
Clients receive examination results matched to the inspection objective, with clear coverage, sensitivity, limitations and acceptance status. The category supports fabrication quality, shutdown inspection, baseline surveys, in-service condition assessment, repair verification and targeted follow-up of suspected degradation.
Typical deliverables
Approved procedure or technique sheet; scan plan; calibration and equipment records; examination report; indication register; images, radiographs or electronic datasets; coverage and limitation statement; acceptance status and follow-up recommendations..
Expected outcome
Clear, traceable technical information that supports safety, compliance, reliability, maintenance prioritisation and lifecycle value.
