Adjustment of Parameters for the Ultrasonic Testing of Welded Joints According to Appropriate Standards

The article presents requirements of currently valid standards concerning ultrasonic tests of welded joints with reference to PN-EN ISO 17635:2010, PN-EN ISO 16810:2014, PN-EN ISO 16811:2014 and PN-EN ISO 17640:2011. The article discusses principles governing the selection of ultrasonic probes, a manner of determining allowances for transfer losses and a manner helping adjust an appropriate test level. In addition, the article characterises techniques applied when setting a reference level as well as analyses positions of probes and a number of beam insertion angles when testing butt joints at various testing levels.
