The words were right there in the footnotes of the engineering drawing: “Must inspect with eddy current.” Yet, there were no indications of what areas of the component were to be inspected, and there were no notes specifying what the eddy current test was supposed to do. Find cracks? Verify heat treat? Check threads?
In keeping with its mission to continuously improve non-destructive testing technologies, UniWest has introduced the new EVi eddy current testing system. Developed in response to industry demand for a portable, high precision, operator-friendly eddy current system, the EVi augments UniWest’s best-in-class signal to noise ratio technology with real-time imaging of the surface under inspection.
As a quality manager, it’s your worst nightmare. One of your best customers comes for a visit and brings a box of cracked parts that came from your plant. He wants to know how it happened, and how you are going to ensure it won’t happen again.
Technological advancements in distance gain sizing result in greater inspection accuracy and reliability.
February 3, 2014
For more than 50 years, Distance Gain Size (DGS) inspections have been performed for the code compliant flaw detection and sizing of welds across oil and gas, power generation and general fabrication applications. They are also used to inspect tubes, pipes, pressure vessels, containers and pumps.
Some modern technology has ancient roots. Hundreds of years ago, foundry workers used sound waves to test the integrity of metal castings by tapping them with a hammer and listening to the tone of the ring.
