Active Thermography in NDT – Advantages, Challenges, Opportunities
InfraTec offers a special seminar "Active Thermography in NDT" for thermography users with a corresponding professional orientation. It facilitates an efficient introduction to this NDT method. It also supports you in assessing for which of your concrete inspection tasks the various methods of active thermography, for example lock-in thermography or pulse-phase thermography, can best be used.
We would like to familiarise you with active thermography in as clear a manner as possible, and in doing so, tie in directly with your experiences.
