Although most professional NDT companies organise a trade test before onboarding a contractor, sometimes, due to time and cost restraints this is not possible. A cost-effective solution is possible using our UTsim online trade tests. UTsim offers virtual machines that work just like the real machine with visible ray tracing and virtual defects that can be drawn for any training or competency assessment. Sample defects can be emailed to an inspector so that he can find and report on the hidden flaw.


Simx NDT recruiters are able to respond to requirements for hard to find contractors, particularly PAUT, TOFD and Pipeline AUT.


Many NDT companies have expressed an interest in incorporating the UTsim trade test in their competency management system. This would enable UKAS as well as the HSE to easily manage the competency audit with a visual image and permanent record of the test results.


Simx NDT staff are available 7 days to man urgent NDT projects for UK, Middle East and Asia/Pacific projects.

Providing global NDT and API training for the inspection profession

"UTman has been a great tool for training on basic UT principles and the training and test mod really helps students build confidence. The ability to see a radiograph and vary the flaws using UT is also very helpful to students. Seeing the shear wave beam reflections helps people visualize key concepts for weld Inspection. I would love to be part of testing and promotion of the new improved UTMan."
