Ultrasonic Phased Array Systems can be employed in almost any test where conventional ultrasonic flaw detectors have traditionally been used. Weld inspection and crack detection are the most important applications. Phased Array produces accurate, detailed cross-sectional pictures of internal structures at fast inspection speeds. The benefits of phased array technology over conventional UT comes from its ability to use multiple elements and electronic time delays to create beams that can be steered, scanned, swept and focused electronically for fast inspection, full data storage and multiple angle inspections.
