From the Editor: Adventures in NDT

October 3, 2007
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.

A Revolution in 3-D Surface Metrology

October 3, 2007
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.

NDT Applications: Making Contact with Positive Material Identification

October 3, 2007
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.

The Power of PCRT

October 2, 2007
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 Advances

October 2, 2007
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.

Ultraviolet lamps

August 14, 2007
The Maxima ML-3500 Series ultraviolet lamps use advanced micro discharge light (MDL) technology plus a filter and bulb/reflector to deliver up to 10X the UV-A output of conventional HID inspection lamps. With these lamps, NDT inspectors can see small surface defects, hydrocarbon contamination and other flaws. All bulbs have a rated life of 2,000 hours. Instant on/off/restrike eliminates lamp warm-up and reduces inspection time. The lamps produce virtually zero emission of hazardous UV-B and emit minimum visible light. The series is available in 120-, 230-, 240- and 100-volt AC versions, as well as in battery-operated versions that include a 12-volt, 7-amp per hour rechargeable battery that will operate the lamp for two full hours. A battery charger and carrying case are included.

Portable leak finder

August 14, 2007
A portable leak finder is available for locating small leaks in chambers, connections or parts. The unit has a rechargeable container for helium gas with a spray nozzle similar to an aerosol can. Helium is sprayed on the suspected leak location of a part or chamber and can then be observed on a mass spectrometer system that continuously measures the helium concentration in the part while under vacuum. A leak is immediately identified if the vacuum inside draws helium into the part or chamber. The kit includes a recharge fitting and comes in a protective, custom-made carrying case. Integral to this fitting are valves, pressure gage and pressure relief valve to allow safe recharging of the canister.
