Testing and Measuring Articles

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.

ISO certification in metal fabrication: Yes or no?

December 15, 2015 | By Dick Kallage

Is ISO 9001 certification worth it? It really depends. If key customers or prospects require it, then yes, it’s certainly worth the effort. But if a fabricator does pursue ISO certification, it shouldn’t be a one-time effort but instead a continual improvement. It isn’t just window dressing.

Exploring the versatility of laser vision systems

August 28, 2014 | By Stephen Thacker

For tube and pipe applications, laser vision systems are commonly used for seam tracking on the mill, but they are useful for many more applications—such as edge bevel measurement; strip width measurement and centering verification; mill process control; and coating control. For pipeline construction, they can verify the integrity of end face bevels and weld bead profile measurements.

Camera-based measurement system sends waves of productivity through fabrication shop

July 31, 2014 | By Eric Lundin

When Bob Burns, owner of Aero Bending Co., Palmdale, Calif., moved his company to a new and bigger location, he considered adding to the company’s fleet of benders. However, a number of bending machine operators often lined up to measure bent components, creating a bottleneck. Changing to an optical inspection system cleared this bottleneck.

Inclusions caught with PAUT

February 17, 2014 | By Eric Lundin

Tube and pipe producers are familiar with ultrasonic testing (UT) which, as the name implies, uses high-frequency sound waves to find discontinuities in tube and pipe. While conventional UT is effective for testing raw materials with simple shapes—round tubing, rectangular billet, and rectangular plate—complex shapes such as castings and assemblies need something more. Phased-array ultrasonic testing (PAUT) gets the job done.

Electronic sensors augment error-proofing, quality control programs

December 2, 2013 | By Dave Bird

Manufacturing is changing—the old hands are retiring, and many left the industry suddenly in the wake of the 2009 downturn. The workforce is smaller and less experienced than before, yet the demands for quality and consistency have never been higher. Electronic sensing and measuring systems can help with inspection and error-proofing in this demanding situation.

How the welder shortage affects the infrastructure

November 19, 2013 | By Professor R. Carlisle "Carl" Smith

The qualified-welder shortage presents significant problems for infrastructure and power industries. New welders need to be recruited, and displaced welders may need to be retrained for today’s jobs.

Taking NDT as far as it can go - TheFabricator.com

Taking NDT to the end of tube, pipe

September 10, 2012 | By Joe Baldauff

NDT systems are limited in how close to the end of a tube or pipe they can test successfully. They rely on electromagnetic or ultrasonic waves to flow through the tube or pipe, and the end represents an abrupt change in the wall’s characteristics, making the test results difficult to interpret near the pipe or tube end. A new system overcomes the conventional obstacles by aiming clockwise, counterclockwise, and transverse transducers at a single point of entry. A timed delay based on the 1-kHz transmit frequency prevents the signals from interfering with each other, enabling the receiver to interpret the results accurately.

Testing OCTG

September 9, 2011 | By Harold Klempner

Hydrostatic testing of oil country tubular goods is done twice—once to test the weld seam, then again after the item is threaded and a coupling attached. Most hydrostatic testing systems test the entire length of the pipe both times, but a new unit, the box-end hydrostatic tester, tests just the threaded portion and the coupling, reducing the time and water needed for the second test.
