Ultrasonic Phased Array (PA) Evaluation
This course is designed to meet the industrial qualification requirements for Ultrasonic Examination using Phased Arrays. The training covers array selection, standardization, TCG creation, inspection design, encoding data, data evaluation and interpretation of data including flaw characterization. Students are encouraged to bring their own Phased Array equipment. The course satisfies the training hours needed for Level II certification in accordance with SNT-TC-1A, CP-189 and NAS-410.
Course Duration: 80 hours
Prerequisite: Students should have a valid Level 2 in conventional UT and experience using the phased array equipment they plan on using for their job.

TESTIMONIALS FROM STUDENTS
“Instructor kept class involved. Teaching style was great.” - April H.
“I highly recommend all my RT inspectors to attend QTS RAD Safety. Ken put on one of the best 40 hour classroom training I have attended over the past 12 years!” - Nick P.
“Ken was an amazing teacher really kept it “exciting”. I can’t recommend him enough.” - Chris
“Another great class. I plan to come back on my own to take my practical and Phased Array. Thank you!” - Chris H.
“The instructor was willing to stay after class to help with individual questions. This is very helpful because everyone has different equipment and work types.” - Jason S.
“Overall I feel as if I learned a lot this week. I feel much more confident scanning with the background knowledge. I would highly recommend Max as a great teacher for this course.” - Emily L.
“The support from Justin and Ken has been fantastic. I have also worked with Matt, MT inspector, and he is very prompt, courteous, very professional and good to work with. I appreciate the help.” - Roger B.
“The real world inspection methods were a great idea. It was bit of a hiccup when Max had to leave for a meeting on day 2. All in all he did a great job covering everything and answering all questions we had. Subject matter was on point and had a nice flow daily. Advice hold on to this trainer and maybe give him a raise!” - Jason A.
‘Max is a very good instructor. He seems to know the material well and did a very good job explaining the different indications and terminology.’ - Joe B.
