Testing arrangement for ultrasonic testing of metallic material blocks using one or move test head arrangements, each test head comprising adjacent probes with overlapping ultrasound beams so that whole internal volume is covered

摘要

Testing arrangement for ultrasonic testing of material blocks (1) for practically complete internal volume and surface testing using a test head group of two adjacent ultrasonic probes (4, 5). Probe separation is chosen so that the field of traverse of the ultrasound beams from the test heads overlap.
