A Primer on the Physics of NDT covers the rudimentary science behind the work we do. You'll learn the fundamentals of electrical theory, as well as magnetism and other related scientific principles.
To dig a little deeper into the principles that drive NDT work, please check out our other courses on specific discplines like Eddy Current, Ultrasonic Testing, etc.
Since this is an intro course, no other prior knowledge is required to take it.
Lee produces educational training content for Tri-State NDT, a best-in-class non-destructive testing company based in New York City. He has a background in signal analysis, project management, media production, marketing and advertising, and technology. He has been working with Tri-State NDT since 2010.
Especially if this is your first time using an online learning platform, it can be a little confusing to navigate the interface. We've tried to make it as accessible as possible, but please don't hesitate to call us up or ask questions if you're having a hard time understanding something.
Much like a traditional academic setting, Tri-State NDT uses quizzes and grades to better understand where each Technician stands in terms of comprehension and comfort with the subject matter.
We believe this is helpful for both the Technician and Tri-State; Technicians do their work quicker and better when they understand what it is they're doing, and we can answer questions and predict problems better based on how you follow certain topics. It allows us to see where there are opportunities to improve training, and identify knowledge gaps to fill.
We use grades and responses in a couple of ways. Firstly, they're used for us to manually review how well each Technician is following the material we present. In the case of a "refresher" course — one that reviews material you've already learned — it helps us understand the retention rate of our training materials.
Secondly, grades contribute to a record we call your EXI, or Employee Experience Index. Simply put, the EXI is a sophisticated calculation of a Technician's different strengths, such as theoretical understanding of the NDT concepts, speed and accuracy during data capture, and so on. Training grades are just one of the components that are weighed to determine that EXI.
Don't stress it; do your best and we'll help you get on board with the material. We want you to do well, and we'll do what we can to ensure it.
