... for inspection of strips and plates
Many different probe configurations were realized so far: The inspection can be carried out in straight test traces or with an oscillating movement of the probes. The most common application is the pre-inspection of strips which are later used for the manufacturing of ERW- or SAW-pipes. The strips are welded together to obtain an endless strip. Within the production line the strip testing system is positioned before the strip is formed into a pipe. The testing speed corresponds to the welding speed of the pipe production, i.e. typically 0.1-0.3 m/s.
