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 />
