"ROBOSKOP" VT-3000 is intended for the nondestructive testing (NDT) of a wide range of parts and provides quick changeover and adaptation to different forms and dimension types of testing objects.
Testing technique and replacing of probes are automatically performed in compliance with the executed testing technique.
During the testing process, "ROBOSKOP" VT-3000 provides the pre-set velocity and movement trajectory, necessary positioning accuracy and probe incidence angle. Applications of the robotized station are determined by its potential NDT techniques:
Eddy current technique (EC) is the basic technique and applied to inspect the parts and assemblies manufactured from the ferromagnetic and non-ferromagnetic alloys in order to detect the surface and subsurface defects, including the cracks, corrosion and thermal damaging. The provided dynamic mode enables to inspect the through bores and attaching holes (with rotary probes).
Impedance technique (IT) - additional mode that is applied to inspect the composite constructions (honeycomb structures) in order to detect disbonds and discontinuities.
Laser scanning (LS) - coupled mode, which is applied to measure the geometrical parameters of inspected parts. See video.
Electromagnetic acoustic (EMA) technique - additional mode, that enables to inspect metal constructions without any contact liquid and work with the materials, having the pain-and-lacquer coating or dirty surface (rust, corrosion, etc.).
"ROBOSKOP" VT-3000provides:
automatic connection/disconnection of the necessary probe;
scanning of the part’s surface along the pre-set trajectory;
tracking of the current coordinates of working probes in a real time mode;
activation of the automatic defect alarm (FAS);
analysis and archive recording of testing results.
Technological advantages:
strict compliance with the requirements of technological process;
minimal time required to carry out the testing;
accurate positioning of the probes;
integration of different NDT techniques.
