Testing and Measuring

Whether you need to measure dimensions or perform some sort of flaw detection on sheet, tube, or pipe, you'll find what you need in this technology area. It discusses measuring coordinates, diameters, and hardnesses; flaw detection using eddy current, ultrasonic, radiographic, and X-ray systems; and using a few other equipment types, such as vision systems and material composition analyzers.

Finding poor-diffusion bonds in ferrous, nonferrous tubes

December 11, 2007

By:

Determining whether a tube seam has a partial bond can be difficult with standard ultrasonic or eddy current techniques. However, multifrequency, probe-based eddy current equipment can detect poor-diffusion bonds in nonferrous materials. Using a penetrating field to reflect a signal off the planar structure of the weld works on ferrous materials.

Bend Process

Bend process monitoring—small changes lead to big results

June 12, 2007

By:

Conventional quality control in tube bending operations usually means detecting the number of links on a tube bending mandrel. When such a system detects that a mandrel link is missing, it shuts down the system so personnel can discard the last bent tube and replace the mandrel. Unfortunately, the broken mandrel link usually is a symptom of a larger problem—one that may have produced poor-quality parts long before the mandrel broke.Another method, process variation monitoring, measures the tension on the mandrel and alerts the equipment operator when the tension changes. This lets the manufacturing personnel know that a problem is developing while it is still small and manageable.
