Ultrasonic thickness gages have progressed since their early development in the 1960s. The first thickness gages were large and bulky. However, they used the same conventional longitudinal, or compressional wave, techniques still in use today. Thickness gages are used in a wide variety of industries including automotive, manufacturing, refineries, power plants, process control, transportation, and oil and gas.
Hardness, as applied to most materials, particularly metals, has been defined in many ways by physicists, metallurgists and engineers. These definitions range from a “conglomeration of properties of a material more or less related to each other” to the commonly accepted idea of “resistance to permanent indentation.” These varied definitions point out the complexity of truly defining hardness so that it satisfies all the criteria associated with the characteristics of hardness.
Olympus NDT has published an “Understanding Phased Array Technology” poster, designed by field experts to present phased array technology in a concise and clearly illustrated manner.
Dr. James Truchard, CEO, president and cofounder of National Instruments, has been elected a member of the National Academy of Engineering (NAE), widely considered the highest honor given in the engineering profession.
Test Equipment Distributors (TED), a provider of nondestructive testing equipment and services to the automotive, aerospace and other industries, has named Mike Hamel president.
Control, the international trade fair for quality assurance, now in its 21st year, remains true to the principles of total practice orientation and marketability. It will be held May 8 to 11 in Sinsheim, Germany.
The Kodak family is deeply saddened by the loss of colleague Stephen R. Mazur, P.E., who was killed in an auto accident on Friday, January 19, while traveling on business in Pittsburgh. An integral part of the sales force at Kodak Nondestructive Testing (NDT) group, Mazur was promoted last year to area manager for the Midwest region.
In the October NDT article featuring Faro Technologies, “NDT Applications: Laser Adjusts Motion System of Ultrasonic Scanner,” the phrase, “With a travel of 40-inches in the X-axis and 18-inches in the y-axis …” should have read 40 feet and 18 feet, respectively. NDT regrets the error.
GE Inspection Technologies (Huerth, Germany) and its Krautkramer ultrasonic products are at the front of using phased array technology in high-speed operations. Copperweld Automotive Group (Woodstock, Ontario, Canada) has installed Krautkramer phased array equipment to ultrasonically inspect tubes for any welding defects created during production.
