The fundamental emphasis is to integrate ultrasonic testing (UT) into  the production process without extra handling and without additional staff requirements.

In modern billet production plants a linear UT testing station is typically integrated immediately after the casting operation in combination with the visual inspection facility.

After removal from the casting pit, billets are laid down and conveyed up to the inspection station.

At this inspection station logs are first visually inspected for surface faults and straightness. Each log is  rotated while the inspector visually checks the surface.

Then the log is automatically moved through the linear UT station. Faulty areas are detected and the resulting data is stored in a database. 

At the crop saw defects are automatically cut out of any faulty log and off-cuts disposed of into a scrap container. Faulty billets, which do not contain sufficient fault-free length are transported straight into a scrap magazine.
