TOFD (Time of Flight Diffraction) is an advanced inspection technique, which combines a high detection rate with a very high reliability in pre-service and in-service inspections. One of the important advantages of using ToFD for weld inspection is the absence of radiation.

SGS Spain organized a training course about TOFD inspections for their local NDT experts. The course was held by the Competence Center for Special Examinations which has many highly qualified specialists in the field of TOFD examination including state of the art technology and inspection procedures.

The training took two full weeks and was concluded with an independent examination in accordance with the European codes and standards. SGS Spain now has 9 EN473 qualified TOFD operators. This will enable them to use the TOFD inspection systems in Spain with support from the Competence Center based in the Netherlands.
