Phased Array

Advanced NDT
Ultrasound Inspection

Phased Array Ultrasonic Testing (PA UT) is an advanced science, using high speed electronics and composite multi-element array probes to produce ultrasonic waves. The UT waves are combined, producing highly accurate images that identify geometry, anomalies, and flaws.

Fast and Accurate – Mechanized scanning of parts with Phased Array UT technology provides 10 to 100 times faster data acquisition of large areas when compared to conventional UT methods.

Industry Recognized – Phased Array technology is recognized for use by almost all governing codes, most notably ASME, which is often a reference code book for most critical and pressure vessel applications.

Quick Archival  – Phased array technology allows for quick archival and retrieval of data, a typical code requirement.

Cost Savings – Substantial on-site cost savings are achieved from speed but even more so from the opportunity to work side-by-side with all on-site personnel. Using UT eliminates the requirement of establishing worker “exclusion zones” associated with X-ray imaging, eliminating any potential for health physics issues or late-night, off-hour, inspections.

Ease of Access – With Phased Array technology, access to tight spaces is possible using miniaturized phased-array probes and semi-automated scanners.

Phased Array Experience

Baker Testing uses Phased Array in a wide variety of applications. Teams of technicians and UT Level III  personnel are available to deploy for small custom jobs or larger scale, high volume part applications.

Power Generation Field Services

The Nuclear Power industry was one of the first to adopt and embrace the use of Phased Array technology for pressure vessel weld inspection. Now, traditional Oil and Gas fired plants are calling upon this technology for Critical Welds in Steam Piping from Headers to feeder tubes ultimately expanding usable life cycles of Boilers.
