Phased Array Ultrasonic Testing<br />

(PAUT) of Piping Welds<br />

GREATER MICHIGAN<br />

We are seeing more and more industrial projects using a new form of<br />

ultrasonic testing method to inspect piping welds in lieu of radiographic<br />

(x-ray) inspection. Compared with radiography, Phased Array Ultrasonic<br />

Testing (PAUT) offers the advantage of process control, as welds can<br />

be inspected soon after completion and feedback can be given rapidly<br />

to the welding crew. PAUT is superior to Radiographic Testing (RT) at<br />

finding lack of fusion defects, especially side wall lack of fusion, as well as<br />

cracks and incomplete penetration type root defects. This NEW course<br />

was designed to familiarize the participants in the basic principles behind Phased Array Ultrasonic Testing with a goal to become<br />

familiar with the displayed information and approaches to analyze test results for determining the location, size, and characterization<br />

of weld defects. In addition, the course addressed the key steps to passing PAUT weld inspections. The course curriculum included<br />

presentations, resources, and hands-on demonstrations of the PAUT equipment.<br />

The UA’s<br />

International<br />

Training Fund<br />

continues<br />

to increase<br />

the focus on<br />

recruiting underrepresented<br />

workers,<br />

including women, to address the growing workforce shortage<br />

and to expand opportunities for promising individuals. Their<br />

goal is to inspire women to apply for their apprenticeship<br />

programs. In an effort to inspire women to apply for the UA apprenticeship program, a Roundtable was held during the ITR. The<br />

purpose was to work jointly and help the UA find ways to overcome common misconceptions about the piping industry when it comes<br />

to recruiting women into our trade. Attendees were encouraged to give suggestions on how we can increase entering into the trades.The<br />

course curriculum included presentations, resources, and hands-on demonstrations of the PAUT equipment.<br />
