Mr. P.Vijayaraghavan receiving the award from Professor. Krishnan Balasubramanian, HOD of Mechanical Engineering & CNDE, IIT Chennai.
14th Asia-Pacific Conference on Nondestructive testing (APCNDT 2013), took place in Hotel Renaissance convention centre, Mumbai, during November 18-22, 2013. More than 800 delegates attended this Conference, which is the largest registration in the history of Asia Pacific Conferences.
The paper , “Life Extension of Helicopter Composite structures by Computed Tomography (CT), by G.Ramesh babu. P.Vijayaraghavan. B.N. Srinivasa Reddy of Composite Manufacturing Division Hindustan Aeronautics Limited, Bangalore complex was presented by Mr. P.Vijayaraghavan . The paper was awarded I prize in the oral presentation Category.
For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors,
the scanning area and the system settings should be flexibly adapted to the test task and the material.
These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.
Applicable for concrete inspection allowing imaging of the internal
structure of objects from conc
rete, reinforced concrete, different
stones. The operation applies pulse-echo technique at one-side access
to the object. The instrument is feasible for concrete inspection for
searching conduct ducts, conduits, detection of foreign inclusions,
holes, honeycombing, cracks and other concrete defects.
The Exertus Dual 120 Projector has the ability to accept Iridium 192
sources or Selenium 75 source
s. This projector incorporates design
safety features that make it flexible, compact and lightweight.
The Projector is lighter than most of its competitors. It
incorporates an improved source channel, based on a new helicoidal
design, which makes maintenance easier. The helicoidal design also
allows smoother movement of the source assembly inside the device,
making it easier for the operator and improving safety. The
Projector also has a unique safety feature not found in competitive
The source assembly locking mechanism is triggered by the source
holder capsule at the front of the source assembly, thereby always
assuring the operator that the source has returned to the
safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
