Inspecting Laser Welds in Component ManufacturingEddyfi
Welding techniques are numerous and each of them has its
peculiarities. Laser beam welding (LBW) uses a laser to
concentrate heat, very quickly producing deep, narrow welds.
Laser welding is common in nuclear applications and highvolume
applications such as automotive component
manufacturing, as well as others where speed and excellent
accuracy are necessary.

Detecting Cracks and Corrosion in Aircraft LongeronsEddyfi
Aircraft are the backbone of several industries and, as such, are subjected to intense and near-continuous use, making preventive maintenance critical. Maintenance protocols are exhaustive but time-consuming, especially when fuselage and wing longerons are involved.
Longerons usually carry larger aircraft loads and help to transfer skin loads to the internal structure. Longerons nearly always attach to frames, ribs, or the skin of the aircraft. Fatigue and stress cracks eventually appear around the fasteners used to secure longerons to structures. Such cracks risk going undetected because they are small (typically 1.25 mm or 0.05 in.), they are near and under fastener heads, and often under surface coatings. The faying surface between longerons and skin is also prone to corrosion and must be inspected.

State-of-the-Art RFT— Meeting the Ferromagnetic Tube ChallengeEddyfi
Ferromagnetic heat exchanger tubing found in petrochemical plants cannot be inspected with conventional eddy current techniques. Common inspection methods for this material include IRIS, magnetic flux leakage (MFL), and remote-field testing (RFT). In general, RFT is preferred due to its defect sizing capabilities, decreased need for tube cleanliness, and high inspection speeds. This application note shows how innovative software features allow working around traditional difficulties encountered with RFT.
RFT is a through-transmission technique where the magnetic field travels twice in the tube wall, which induces important amplitude attenuation and phase lag. This double diffusion in the tube wall makes the RFT technique very sensitive to any nominal thickness variations and permeability change. This high sensitivity brings several challenges:
• Typically, the manufacturing thickness tolerance of carbon steel tubes is approximately 10 %. But such a variation in thickness can represent a rotation of about 60° on your channel, which greatly affects sizing interpretations.
• The magnetic permeability of carbon steel varies from grade to grade and according to processing history — tubes processed at high temperatures do not have the same permeability than those processed at low temperatures. Such variations in permeability have a considerable impact on RFT sensitivity and depth sizing.
• Calibration tubes matching the properties of tubes to inspect are extremely hard to come by. Differences in thickness and permeability almost always make calibrations inadequate without the proper tools to compensate.

Assessing Circumferential Cracking in Non-Ferromagnetic Heat Exchanger TubesEddyfi
Heat exchangers are used to heat and cool various fluids across a wide spectrum of industries. This is especially critical to the power generation and petrochemical industries where fixed equipment reliability is paramount. Tubes in heat exchangers made of such materials as austenitic stainless steel and Inconel are plagued by circumferential cracking, which conventional, single-coil eddy current testing (ECT) cannot reliably detect.
This application note explores how an innovative probe technology is able to address this challenge.
Non-ferromagnetic heat exchanger tubing is susceptible to circumferential cracking in the vicinity of the tubesheet. These cracks are induced by the localized stress created during the tube-to-tubesheet rolling process.
Circumferential cracking is very difficult to detect and characterize with standard eddy current bobbin probes, currently the norm in the industry to inspect tubes, because:
• bobbin probes are very sensitive to tube expansion and ferromagnetic materials, out of which tubesheets are usually made. When analyzing bobbin coil data, it is very difficult to
isolate a small-volume crack from a complex signal comprised of a crack, a geometry change, and added material;
• the orientation of standard bobbin coils is not well suited to circumferential cracks because eddy currents flow parallel to the indications.

Twisted Tube ® Heat Exchanger Inspection with Eddy CurrentsEddyfi
Heat exchangers are essential to the operation of many systems in various industries, processing plants and electric power generation plants, for example. A unique type of heat exchanger (HX) was introduced several years ago: the Twisted Tube® HX. They offer the highest levels of efficiency, but have always been a challenge for periodic inspections. Until now.
A twisted tube is composed of two straight, circular sections near the tubesheets, separated by a length of helical, oval tube. This helix creates a small, central circular passage along the length of the tube where traditional bobbin probes can be pushed and pulled.
However, standard ECT probes deliver suboptimal performances — detecting, characterizing, and sizing flaws are problematic because of poor signal-to-noise ratios. Flaws on the wall furthest away from the tube’s center (crest) produce much smaller, distorted signals than same-size flaws in the narrow section, closest to the tube’s center (dip). This is because of the liftoff created by the tube’s geometry between its walls and the ECT probe. This amount of liftoff translates into a lower probability of detection and less accurate sizing.

The avanti group sharp turn for electronics company
1. The Avanti Group Sharp Turn for Electronics Company
The Avanti Group is advising clients on the recent developments
surrounding Sharp Corporation and their expansion plans to
move within surrounding Asia.
June 17, 2013 - The Avanti Group the equities research house
based in Tokyo, providing professional trading and investment
research solutions to institutional and private investors across
the globe have recently drawn their investor’s attention to
recent announcements made by Takashi Okuda president of
Sharp Corp.
2. “Sharp Corporation is a well-established company
manufacturing electric telecommunication, electric and
electronic equipment split into two business segments of
equipment and component. We see the recent announcement
to expand manufacturing outside Japan as positive growth, as
Abenomics path has resulted in a number of manufacturers
looking to resettle outside Japan due to the Yen’s
strength, imports costing more and less goods being
exported, the move for Sharp will increase its sales with an
estimated growth to sales by 2017 of ¥300 billion,” said Richard
Armitage Director of Private Equity at The Avanti Group.
3. Sharp Corp Japan’s No. 3 televisions maker, are among the
growing company list evaluating new operations abroad as
means to increase their foothold throughout Asia. Sharp Corp’s
operational director for Asia- Pacific commented to a source
close to The Avanti Group to say, products such as air-
conditioners, washing machines as well as refrigerators are
expected to see high growth down the road in six main ASEAN
markets.
4. “The household electrical and component manufactures share
price has been on a gradual upward trend since August 2012
with recent developments in Abe’s growth strategy the share
price has dropped 18 per cent in May due to export restraints.
However with the announcement of this move and the recent
management reshuffle we see the price set to increase to good
gains, we are advising our clients of the right entry point back
into this market,” concluded Richard Armitage Director of
Private Equity at The Avanti Group.
The Avanti Group is an equity research house providing
research and analysis outsourcing solutions for institutional
financial traders worldwide, founded in early 2003.
