Eddy Current testing - Quality Inspection Services at Trinity NDT

 Trinity NDT, Bangalore, India has updated its Website as a part of continuous improvement for better customer service. Recently added complete new updated page for Eddy current testing and training, certifications on ET Level I, II. Trinity NDT has the latest equipments on ET capable of detecting flaws, materials sorting using eddy current principle, non conductive coating thickness measurement and other quality control and engineering applications. Log on to read more on our Eddy current testing facilities with Trinity NDT at our webpage:

In Eddy current testing or electromagnetic induction tests, the test object is place in the varying magnetic field of a coil or an array of conductor carrying A. C current. Ac current induces magnetic filed which is constantly varying in both polarity and amplitude every faction of a second. Varying current induced magnetic field which also varies according to the frequency of alternating current. This varying magnetic field induces current in the adjacent conductor which opposes the primary current causing it according to Lenz's Law. This opposing current in turn cancels the primary current that depends on the characteristics of materials being tested. The currents which are swirling like pattern are called Eddy currents.

@ Hotel Radha Regent
171, Jawaharlal Nehru Salai
Chennai – 600 106.

Organized by The Indian Institute of Welding
Chennai Branch

The Indian Institute of Welding (IIW-India), a representative body of professional welding engineers in India, is involved in the advancement of welding science and technology within the country by disseminating development and knowledge in the field of welding and allied technology through seminars, workshops training programme etc., providing technical guidance and consultation to industries in welding, conducting associate membership examination and awarding diploma and  certificates to members, and publishing technical journals and periodicals in the field of welding. The IIW- India has been recognized as an Authorised National Body (ANB) to carry out certification programmes of the International Institute of Welding.

IIW-India also conducts its own welder certification programme, the National Welder’s Training and Certification Scheme (NWTCS). Directorate General of Employment & Training (DGE&T), Government of India, Ministry of Labour & Employment has empanelled IIW-India as an “Assessing Body” for MES courses under Skill Development Initiative (SDI) Scheme for all courses under Fabrication Sectors in all States and Union Territories in India.

The Chennai Branch of IIW-India, formed in 1973, has made good progress over the years with respect to membership, technical programmes etc, due to the unstinted support of industries in the region and selfless efforts of various members and office bearers. Today the Branch has over 400 members and 25 Industrial Corporate members. The Branch organizes technical meetings every month, courses and seminars of topical interest and visits to important projects.

With our country in the midst of a quantum leap to industrialization, the Branch hopes to contribute effectively towards improved productivity, cost effectiveness and quality enhancement to the welding fraternity in particular and industries in general. The Chennai Branch constantly audits its position and develops strategic plans to meet the latest objectives of our Country’s development.


India’s long-term nuclear power programme is based on utilising the vast indigenous thorium resources available in our country, for electricity generation. India’s uranium resources can support a first-stage programme of about 10,000 MW based on Pressurised Heavy Water Reactors (PHWRs) using natural uranium as fuel and heavy water as moderator and coolant. The energy potential of natural uranium can be increased to about 3,00,000 MW in the second stage though Fast Breeder Reactors (FBRs) which utilise plutonium obtained from the recycled spent fuel of the first stage along with thorium as blanket, to produce U-233. With the deployment of thorium at third stage using U-233 as fuel, the energy potential for electricity generation is large and substantial. Indigenous industrial infrastructure for reactor programme is well-developed. Special infrastructure for the production of fuel, heavy water, reactor control and instrumentation has been developed within the Department of Atomic Energy. Indian industry has gained valuable experience and reached a stage of maturity in manufacturing equipment components and handling of mega package contracts for these reactors.

The research and development activities for the FBR were carried out at the Indira Gandhi Centre for Atomic Research, Kalpakkam. The commercialization of FBR has started with the under-construction Prototype Fast breeder Reactor at Kalpakkam by the Bharatiya Nabhikiya Vidyut Nigam Ltd.
(BHAVINI Ltd.). A number of components required for the PFBR have been fabricated by a number of big private industries.

Dr. Prabhat Kumar, Chairman and Managing Director, BHAVINI Limited, superannuated on 31 October 2014. Dr. Prabhat Kumar has been an active member of the Indian Institute of Welding. He has contributed significantly to the development of the Institute. He is currently the Chairman of the
ANBCC Committee of ANB of the Indian Institute of Welding.

The Workshop is being organized on 20 December, 2014 to honour Dr. Prabhat Kumar on the occasion of his superannuation. The workshop will cover innovations in materials, fabrication and inspection technologies in nuclear industry. A separate function to felicitate Dr. Prabhat Kumar is also planned.

  • Nuclear materials and innovative techniques in fabrication of large equipment to stringent tolerances
  • Experience of quality assurance in installation of sodium systems in Prototype Fast Breeder Reactor.
  • Unique and Exclusive design and construction features of heat exchangers and steam generators for nuclear reactors
  • New and advance technology mega projects: Paradise for management professionals and delight for technocrats
  • Welding and inspection challenges in nuclear industry

Participation in this workshop is both by invitation and by registration as delegate. Invitees are exempted from paying the registration fee. This workshop would be useful for engineers and scientists from different units of Department of Atomic Energy and to engineers from industries closely associated with fabrication of components for various nuclear power plants in India. Workshop shall also benefit those in academics dealing with nuclear and power plant engineering. Entrepreneurs and small scale industries who are keen on participating in fabrication of nuclear components shall also benefit immensely from this workshop.

Last Date of Registration: 15 December 2014

Advanced Ultrasound-based cameras for 2D and 3D Inspection of Composite Materials

Advanced Ultrasound-based cameras for 2D and 3D Inspection of Composite Materials

Dolphitech AS provides advanced ultrasound-based cameras for 2D and 3D identification, inspection and analysis of defects in composite materials. The Company uses advanced technology developed by a team of experts in ultrasound, analogue and digital electronics.

DolphiCam is a mobile and ergonomic ultrasound camera system designed for NDT inspection of CFRP (Carbon Fiber Reinforced Plastics). The camera uses a unique dry-coupling transducer technology with high performance signaling electronics creating high-resolution 2D and 3D images of suspected damage areas to verify the status of the material. We have now released a new product, DolphiCam Research, which gives scientists access to advanced camera control features such as raw data sets for further material analysis and user defined pulses.

DolphiCam is a mobile and ergonomic ultrasound camera system designed for NDT inspection of CFRP (Carbon Fiber Reinforced Plastics) creating high-resolution 2D and 3D images of suspected damage areas. The camera supports A-, B- and C-scan images, supporting both Amplitude and Time-of-Flight.

Unlike Phased Array systems, our matrix transducer gives simple, high-resolution images without moving the transducer, or using an encoder. The silicone-based transducer pad allows dry coupling on painted or shiny surfaces, and water or contact gel can be used on rougher surfaces.
