Centre of Excellence for Advance Manufacturing Technology develops grounding projects in AI – iWeld & iToFD

IIT Kharagpur has proven its Tryst with Innovation with its latest dominant supremacy in the field of Artificial Intelligence with two of its ground breaking projects on AI-enabled non-destructive testing for weld defect analysis, from Centre of Excellence in Advanced Manufacturing Technology (CoEAMT),  IIT Kharagpur led by Prof. Surjya K Pal, Chairperson, Centre of Excellence in Advance Manufacturing. These two innovative solutions have been shortlisted by TATA STEEL for “TechEx 2024” exhibition.

The first, “iWeld, an AI-enabled NDT” software is an innovative solution developed for Garden Reach Shipbuilders & Engineers (GRSE)  Kolkata, Ministry of Defence. iWeld is designed to identify, localize and classify different types of weld defects, such as blowhole, wormhole, porosity, lack of fusion, and inclusion, from radiography images with remarkable accuracy. The performance of the iWeld has been certified by the Indian Register of Shipping (No.: 2023PC001, Dated: 9th Aug 2023). This was also recently shortlisted as one of the four innovations from IIT Kharagpur which were showcased at “IInventiv 2024” – the first-of-its-kind, mega R&D fair, where all IITs, NITs and other top Institutions in the country participated to show case the their cutting-edge innovations in R&D.

The ability of iWeld to enhance the quality and efficiency of weld inspections has marked it as a truly successful product, standing as a testament to successful collaboration between CoEAMT and GRSE. Jointly copyrighted with GRSE, iWeld is now primed for commercialization. Mr. Avishek Mukherjee, a Doctoral Scholar in Advanced Technology Development Centre, has devoted considerable effort and dedication to bring about this development.

“Recently, this has also been selected and showcased by the mega technical Event, IInventiv 2024, organised by MoE at IIT Hyderabad. This software is already certified by Indian Register of Shipping, and has been handed over to GRSE for daily operational usage with human-like accuracy. This software has been jointly copyrighted with GRSE as well. It is a product with TRL:8/9. GRSE and CoEAMT will now jointly go ahead for commercialization at other industrial ends. AI-enabled NDT for auto evaluation of weld defects from Ultrasound data: This project is being funded by TIH. It has already been filed for patent. A group of students at CoEAMT are planning to spin-off soon with these AI-enabled NDT solutions for weld defect analyses. Our students are doing wonderful job. Their success for solving perennial industrial problems is awesome. The credit goes to the interns and scholars,” said Prof. S K Pal, Chairperson, CoEAMT.

The second solution, “iToFD“, under a project funded by  (TiH) of IIT Kharagpur, revolutionizes the detection and sizing of weld defects using ultrasonic time-of-flight diffraction (ToFD) data. This cutting-edge system integrates advanced signal processing with AI algorithms for precise defect localization and measurement. This automated solution, patented recently (Patent filed ref no: 202331060331), is nearly 15 times faster than traditional manual inspections. Mr. A K Vishwanathan, Undergraduate student in Chemistry; Mr. Sarvan Kumar Singh, Undergraduate student in Chemical Engineering; Mr. Ananta Dutta, Doctoral Scholar in Mechanical Engineering, and Mr. Avishek Mukherjee, Doctoral Scholar in Advanced Technology Development Centre are diligently contributing to this project.

“The Centre of Excellence in Advanced Manufacturing Technology at IIT Kharagpur is geared up in solving various perennial problems of the industries through deployment of artificial intelligence, and Industry 4.0 concepts.   I am extremely happy to see the passion of students associated with the CoEAMT while working with the industries, at this stage of their lives, providing innovative solutions.

IIT Kharagpur handed over Industry 4.0 solution to GRSE

The Centre of Excellence in Advanced Manufacturing Technology (CoEAMT) of IIT Kharagpur has handed over its Industry 4.0 solution to Garden Reach Shipbuilders and Engineers Limited (GRSE), under Ministry of Defence. The Centre has developed a software for GRSE, named iWeld wherein AI will detect the defective portion from weld radiography images and classify the type of defect. Tested over large number of samples at GRSE, it gives a very high accuracy of 93.18%. The software has been developed by Mr. Avishek Mukherjee, Doctoral Scholar of IIT Kharagpur under the supervision of Prof. Surjya K Pal, Chairperson of the CoEAMT and Professor in the Department of Mechanical Engineering of IIT Kharagpur.

iWeld is likely to replace the need of skilled weld supervisors in near future to evaluate the X-ray films. Additionally, CoEAMT has also taken up another project for Research & Development Centre for Iron & Steel (RDCIS) Ranchi, Steel Authority of India Limited (SAIL) to do the vibration data analytics of exhauster fan in steel industries. The Centre of Excellence in Advanced Manufacturing Technology has also bagged Rs 30.18 Cr project fund in phase-2, from the Ministry of Heavy Industries (MHI) and Public Enterprises, Government of India to develop various solutions on futuristic manufacturing domains such as cobots in manufacturing, Augmented and Virtual Reality in training and process quality monitoring, affordable healthcare equipment manufacturing, Industry 4.0 solutions for composite wind turbine blade manufacturing etc. with the help of various industries such as Tata Steel, Tata Motors, Tata Metaliks, TCS, Tata Medical and Diagnostics, and LM Windpower.

On the lines of Industry-Academia Collaboration, Prof. Surjya K Pal remarked, “I am sure with such affiliations from Industry and Government funded projects, and regular short term courses on modern manufacturing concepts, and hands-on training programmes throughout the year, the prominence of the Centre will steer ahead. Understanding the country’s need of reskilling and upskilling the manpower on modern manufacturing concepts, CoEAMT provides hands-on training on CNC to working professionals, technical staffs and students. The CNC training that took place from 5th December to 9th December 2022 for the sixth time, had total filled-in participation comprising of working professionals from MSMEs and technical staff members from academic institutes like IIT Kanpur, IIT Goa, students from IIT KGP and many more.”

The Centre of Excellence in Advanced Manufacturing Technology has been established at IIT Kharagpur through the support from the Ministry of Heavy Industries and Public Enterprises, Government of India, along with a consortium of top six industry members in the country in 2018. The centre aims to stimulate the innovation in low-cost manufacturing solutions for various industries while working in a synergistic way towards the common goals of infusing cutting edge technologies, and to come up with research and development for sustainable products.

His story

For the Diwali of 2019, the Delhi government held a laser show event for four days to keep people away from bursting crackers. For some years now, laser technology has quietly made its way into the hi-tech sound and light shows at several forts of Delhi, Rajasthan and Andhra and has even become a feature at permanent theme park installations. Indoor and outdoor laser multimedia shows are part of popular entertainment at sporting events, trade shows, corporate events, concerts, product launches and family parties that range from birthdays to stylized weddings.

In other words, laser multimedia shows have arrived and are now making their way into the family circuit. So what does it have to do with IIT Kharagpur? Well, KGPians are trendsetters and, as with so many other industries where they blaze the trail, in this particular field too, a KGPian has been making his impact felt.

We are talking about Naveen Sharma, Co-Founder & CEO of Prachin Bharat Tourism Technologies Pvt Ltd, which specialises in producing laser shows on historical subjects. Since its inception in 2007, the company, which was setup as a social entrepreneurship venture, has been trying to showcase the historical places of India using modern technology.

Naveen started by showcasing the history of Nalanda in 2008. This was the place his parents came from and so he was strongly attached to it. By merging 3D video technology and animation, and the voice over provided by Harish Bhimani, the famous writer, anchor and voice-over artiste, the show was inaugurated by no less than Bihar’s chief minister, Nitish Kumar. The next show was at Bodh Gaya, when the Dalai Lama came to inaugurate the Kal Chakra. In 2012, the company also released a multimedia book on Nalanda and the same year followed a mega laser show at Gandhi Maidan watched by 3 lakh people on Bihar Diwas. It has been a regular on Bihar Diwas since then.

Prachin Bharat has done shows on several historical subjects, such as Bhagat Singh, Guru Gobind Singh. It has worked on the Life of Buddha, History of Pataliputra, History of Mysore, Gandhi’s Champaran Movement, the life of 1857 warrior Kunwar Singh. The company has permanent installations at the Buddha Smriti Park in Patna, and runs regular laser shows and musical fountain at Mangal Talab, Patna Sahib, and inside the dome of Gol Ghar in Patna. There have been shows at IIT Delhi and in the Mysore Palace grounds, which was telecast live on Doordarshan. There have been shows abroad as well. For example, in Brampton, Canada in 2017, on the life of Guru Gobind Singh, one of its most successful shows so far that was witnessed by around 3,500 people including dignitaries. Currently, Naveen is working on the ‘Making of Mahatma’ based on Gandhi’s autobiography, and on Guru Nanak.

So how did the 1992 BTech in Civil engineering get here?

Naveen says, “Just after doing my B.Tech, I joined Tata Steel, Jamshedpur in the Computer Services Division. After working for two years, I decided to go abroad like everyone else. I worked as a software programmer with Citibank NA, Singapore for six months, then IBM, Jakarta and then Bankers Trust, New York, and IBM labs, Boulder Colorado. I then decided to move back to Bangalore in 1997 and joined Command International Software. I began a start-up in 2000, called Infinite Computer Solutions, and then joined Cisco Systems in 2001. Finally, I started our own company in 2007 with another colleague of Cisco Systems. I ran the two in parallel with a one year sabbatical in 2011-12 from Cisco, which I finally quit in 2015. Since then there has been no looking back.”

The change wasn’t easy, says Naveen, and not without a lot of soul searching. Perhaps the biggest influence on him that prompted him to think along these lines was what he witnessed in Israel. He was inspired by examples of Israel as to how that country has showcased its history. “We bring history and technology together, and often this is not easy to bring together,” says Naveen. Most of the international laser shows do not do that, he says. Naveen takes a lot of care to draw up the literary content of these shows, not only making sure their authenticity but also, at the same time, to assure their appeal to the people. The fact that he comes from a literary background helps, but he also ensures that experts are roped in.

Naveen also mentions the unique role IIT Kharagpur played in his switch of career. “My days at KGP were the best. I was the Dramatics secretary of Gymkhana in my second year. That, and probably my literary back ground, has helped me to get into show business. My times at KGP were spent more outside the classrooms and libraries with my friends discussing all possible things on earth.”

Prachin Bharat today is a completely self-funded, boot-strapped company run from Bengaluru. “Our people are our strongest assets”, says the company’s website. Naveen says that he has on board several of his former colleagues from Cisco, and even a KGPian – Satyajit Sahu – who he describes as an “RK guy and wonderful guitarist”. Naveen and his partners sometime buy software from abroad but depend entirely on the expertise of a team of Indian professionals to create the final content and execute the actual show on their shoulders.

He compares any start-up journey to that of a rocket lifting up from the ground. “From level zero to one requires enormous amount of energy. From level 1 to 2, one has to give his or her 100 per cent. It is only from level 2 to 3, when the company starts stabilizing, that the energy requirement tapers off.” He also reminds the entrepreneur that no venture can be entirely about financial gains. There has to be a ‘purpose’ at its heart. And the last but not the least – avoid limelight because that always distracts.
