Phased array technology for standard ultrasonic testing

摘要

The results of a phased array ultrasonic instrument have been presented. The direct, simultaneous representation of the test results as sector scan, C-scan and B-scan in two views (transverse and longitudinal) is the logical development of ultrasonic testing technology in the direction of imaging the test results. However, the requirements of non-destructive testing differ from the scans which are known in medical diagnostics: in addition to the sector scan we also require the further views described here. Conversion to instrument technology is also more expensive than in medicine because the physics of sound is much more complex in solid workpieces than in organic tissues. The solutions for the application of the phased array technology are already available, thus the conversion to test practice is only a matter of time.
