Electromagnetic test methods for welded carbon steel tubing

July 11, 2006

By:

Although eddy-current testing is king in the tube production industry, flux leakage is worth a look. Using a small test sample, equipment-maker InspecTech found that for 3.50-in. to 4.00-in. carbon steel tubing with wall thickness from 0.056 in. to 0.100 in., the flux leakage method found more defects and turned out fewer false alarms than the eddy-current method did.

Mission: Spectacular scrap handling operations

July 11, 2006

By:

Stampers, precariously squeezed by tight margins, high material costs, and increasing pressure to be leaner, have issued a request: we want our scrap handling operations to be faster, trouble-free, and more productive. Fortunately, the latest generation of scrap handling equipment makes that mission possible. New machinery, trending toward a greater use of invisible forces and high-tech gadgetry befitting a spy thriller, is equipped with sensors, edge-guide systems, automation, and magnetic forces, equipment manufacturers say. In addition, significant improvements have been made to the scrap handling equipment itself to save space, minimize jams, and to keep it moving.
