Automated ultrasonics (AUT) is more reliable, faster, has better detection of critical Lack of Fusion defects in pipeline construction welds, and poses no safety hazard compared with radiography. Phased arrays also present major improvements over conventional multiprobe ultrasonics, both for onshore and for offshore use. Probe pans are lighter and smaller, permitting less cutback; scans are quicker; phased arrays are considerably more flexible for changes in pipe dimensions or weld profiles, and for different scan patterns; phased arrays can perform 'specials', such as inspecting seamless pipe of variable wall, clad pipes, thick and thin sections, and use automated set-ups. This paper describes the PipeWIZARD ultrasonic phased array system for girth weld inspections, track record and acceptances, and some of the special applications. These include: Compensating for variations in seamless pipe wall thickness, wedge temperature compensation, premium inspections for risers, tendons and other components, small diameter pipes, multiple displays, clad pipe, portable phased arrays for tie-ins and repairs and improved sizing approaches.
