The American Society for Nondestructive Testing (ASNT) Fall Conference and Quality Testing Show will be held November 12 to 16, in Las Vegas, Nevada, at the Riviera Hotel.
My latest adventures of roving editor-at-large in the world have recently taken me to Québec City, Canada. Although I’ve been to Ukraine, the Czech Republic, Hungary, Germany, Austria, France, Italy, England and Spain, along with Ecuador, Argentina and Mexico, I had never actually been to see our neighbors to the north.
The use of X-ray-based nondestructive test methods dates back more than a hundred years, with the advent of film-based radiography. This article describes a number of X-ray-based offerings for today’s nondestructive testing applications.
Traditional measurement of surface texture using 2-D profilometers has major limitations. It gives satisfactory results for isotropic surfaces that present identical features regardless of the direction of measurement. The method also can be applied to some anisotropic surfaces in accordance with ISO 4288, such as turned surfaces with representative profiles that are perpendicular to tool marks. But it does not provide a general solution.
Quality procedures are put in place to document materials as they are received and as they move through the production process, but what happened to those raw materials before they arrived at the receiving dock? This was the problem facing St. Cloud, MN-based DCI Inc., a manufacturer of stainless steel and nickel alloy vessels and equipment.
Must quality engineers and product managers always be at odds? The former seeks perfection while the latter pushes for greater throughput. With the latest improvements in leak detection devices, both agendas can be served, as the best examples of this testing equipment help speed the quality control process without sacrificing accuracy.
Acceptable product performance is the ultimate goal of any manufacturer. This requires not only well-controlled material input and process control for making acceptable products, but also a way to ensure that, when products are used where failure could be dangerous or expensive, a screening method ensures the rejection of unacceptable products. Performance-based screening using NDT is an approach to guarantee that high-performance, quality parts are shipped to the customer.
Infrared thermography is the science of detecting and measuring variations in heat emitted by an object and transforming them into visible images. It is a rapidly developing technology for nondestructive testing (NDT) in many applications. Recent advances in imaging equipment allow for more rapid data acquisition and higher spatial resolution, thus opening up new areas of application.
After a summer filled with toy recalls because of defective magnets and excessive lead paint-as much as 180 times the acceptable levels, according to some experts, I think that the holidays will be much different for many families with children this year.
Being in the calibration business for such a long time means we’ve had our share of weird requests, as have many of our customers. While providing a laugh from time to time, lately we seem to be getting more of them and that’s downright scary.
