2 D E F E C T O M A T D I – M u l t i - l i n e s u p p o r t f o r e d d y - c u r r e n t te s t ing DEFECTOMAT DI based on the compact eddy-current tester DEFECTOMAT CI, which is worldwide successfully in use. New is the stringent separation of the test unit (electronics for eddy-current testing and interface to the testing line) and the operation unit (electronics for signal display and storage of test results). This action enables the functionality of multi-line support from a single operation unit. The field of application is diversified and varies from the 1-channel evaluation for many...

3 In tube welding lines, using the differential and absolute channels to monitor the weld quality with weld probes or segment coils. The optional absolute channel detects open seam tubes. In endless wire lines, e.g. drawing lines or rewinders, the section-specific evaluation of defect signals over selectable limit values produces three quality statements. For stainless steel wires with small diameter the sensor system Minicoil is recommended. The test coil guides itself on the wire and is therefore able to balance variation in the tensile strength and direction. In tube and bar stock finishing...
