NDT by inductive heat flux thermography between real defects and noise signals. Before testing, the test piece is wetted fine for homogenisation and increasing of the emission coefficient. The induction coil heats up the test piece in which defects open to the surface produce a local temperature increase that is proportional to the defect depth. Four infrared cameras scan the

DEFECTOVISION ® IR is the most recent development from Institut Dr Foerster, which extends the company’s core competency for non-destructive testing of metallic semi- finished products by applying the technology of inductive heat flux thermography. The infrared technology represents an innovative approach to non-destructive testing applications that, until now, have not been successfully solved using traditional NDT technologies. As a first step, Foerster presents a new solution for surface testing of hot-rolled steel tubes and billets with round and square cross sections. More advanced applications are under development and will be available in the future. Traditional technologies for testing steel tubes and billets with inductive thermography only collect and evaluate the temperature of the surface area once. Foerster developed a new evaluation method (patent applied for) that is based on the dynamic temperature profile on the surface over the complete visual field of the camera. This additional time dimension ensures a reliable and repeatable separation
