KALMAR 32+

The scanner is installed in the center of the weld.
With the help of a mechanized drive, the transducers on the PA move along
the forming weld along the entire section of the rail (head,web and base blades).
The software includes standard settings for the control of welded joints:
aluminothermic, electrocontact and gas-pressure welding.
In real time, a "B" scan is formed on the screen of the flaw detector
in the form of a rail contour with defect parameters: coordinates,
location in the section of the weld, conditional dimensions, detection coefficient.
A detailed analysis of all signals is available in the "A" and "S" scans.

FEATURES AND ADVANTAGES 

• Alarm about the presence of defects – sound and color on the monitor of the flaw detector; Determination of control parameters using the calibration standard EN 13674;

• The presence of the acoustic contact tracking function;

•  Saving control results in the database, including diagnostic parameters (sensitivity, study time, conditional dimensions of defects, detection coefficient), GPS coordinate;

•  Functions "auto-size" and "auto-protocol".

The control parameters are set using the CO-3P instrument in a semi-automatic mode

Information is presented in B and D scans

Defectoscopic data analysis is conducted in A and S scans. The determination of flaw dimensions and their coordinates is done automatically

Supplementary inspection is carried out using a manual detector of phased arrays with an entry angle range of 36-75 degrees. The inspection results are recorded in the form of defectograms in the protocol
