The robotic complex ROBOSCOP VTM-5000/RSP is designed for nondestructive testing of welded rail joints in the technological flow of rail welding companies. ROBOSCOP VTM-5000/RSP manages laser geometric parameters measurementof railweld joint, hardness measurement, videomonitoring in the area of possible burn and ultrasonic testing over the entire rail section of the rail using phased arrays probes.
Main functions of the VTM-5000/RSP Roboscope:
- Ultrasonic testing of the welded joint in full compliance with current requirements;
- Determining the position of the welded joint;
- Determining the temperature of the welded joint in the testing zone;
- Search for burn-through in the weld joint area;
- Profilometry (laser scanning of the weld joint);
- Providing supply of contact fluid to the testing zone;
- Automatic adjustment of ultrasonic testing parameters;
- Automatic testing of the significant setting and probe parameters;
- Drafting a joint testing protocol and testing log;
- Drafting a rail string log.
*To search for cracks in the blind spot (8 mm) from the tread area, the system can be retrofitted with an eddy current testing unit.

ROBOSCOP VTM-5000/RSP is used at rail-welding enterprises, providing full quality control of the products in accordance with the acting regulations.The output (acceptance) inspection of contact welded railjoints is performed by an echo-pulse method with phased array probes. The rail scanning area in the weld zone (250 mm) is programmed according to the guiding documents by RZD,JSC.
The ROBOSCOP VTM-5000/RSP system is integrableinto a process flow of rail welding factories as a separate module of the rail line (of roller conveyer).
ROBOSCOP VTM-5000/RSP is programmed to perform ultrasonic testing of each welded joint throughout the section, laser measurement of geometric parameters and hardness testing of the welded seam. The number of testing zones and the sequence, as well as the parameters of the defect alarming (gate level), are specified in the system settings. Welded joints ultrasonic testing includes: rail base point, rail base, rail web and rail head.Welded joint geometrical parameter laser measurement is carried out by a 2-axis triangulation sensor, the use of additional measuring instrument such as master-straightedge isn`t required. The probes trajectories calibration in connection with the rail flapping (displacement) in the rolltable during the motion is performed automatically by the initial laser measurements.
The inspection total time, including laser geometric gaging and the formation of an "on-line" protocol takes less than 3 minutes.
