PC with the latest version of ES Beamtool, Setup Builder, or similar can be used. All equipment must be registered and calibrated before the expiration date. 6 - Calibration Perform an element check and ensure that each element is within 3dB amplitude of adjacent elements. The number of dead elements in the same active aperture should be a maximum of 1 out of 16. Save the data and generate a report with the filename: Name-Date-ElementCheck. Perform a calibration with the encoder over the entire scan distance. Reference reflectors according to DS/EN ISO 13588 Table A.2 should be used for the calibrated TCG.
7 - Execution of Testing Retrieve the pre-stored file for lamination control and thickness measurement. Use the standard probe with wedge SA0L for this purpose in the base material and the inspection area. When scanning the weld: 1- Retrieve the pre-stored file for sector scan. 2- Check that cables and connections are intact and functional, ensure good coupling between the probe and surface (thin liquid oil) – calibrate all "beams" for speed, surface delay, and sensitivity. 3- Set gates and measurement areas suitable for the inspection. 4- Mount the probe to the encoder, set sector scan to cover the root area and volume, set index offset (-) 90 skew with encoder inversion, see attached Beamtool file: PAUT 112-SS-T25-300 mm. 5- Apply couplant to the entire scan area and place the probe where the inspection is to begin.
