Crucial test: Samudrayaan inches closer to mission
BENGALURU: India's ambitious first-manned ocean mission Samudrayaan is inching closer to reality, with ISRO on Wednesday announcing that the testing of the personnel sphere of the Matsya-6000 submersible, along with the development of materials for realisation, were successfully carried out at the Vikram Sarabhai Space Centre (VSSC). 'The first welding on the actual hardware and detailed evaluation has been completed. High-penetration welding of this scale, ie. of 80-mm weld thickness, over 7,100-mm length with 32 minutes of weld duration, was carried out for the first time in the country,' ISRO said. Matsya-6000 is a sphere comprising a diameter of 2,260-mm, made of Titanium, and is expected to withstand external pressure of up to 600bar under low temp situations of -3 degrees C. It is capable of carrying a three-member crew, up to 6 km deep into the ocean. The National Institute of Ocean Technology (NIOT) signed an MoU with VSSC for the development of the special human-occupied spherical vessel, as a part of Samudrayaan, under the Deep Ocean Mission. The scientists also said a major challenge in realising the spherical vessel was the development of reliable, high-penetration Electron Beam Welding process and the high-energy (7.5MeV) X-ray facility for the Non-Destructive Evaluation. This is essential for the certification of the human-rated product, the ISRO team said. The Liquid Propulsion Systems Centre (LPSC) in Bengaluru developed the process and infrastructure for the welding process and NDE. ISRO said the LPSC has the facility and expertise to carry out welding up to 20-mm thickness. To meet the high-power demand, the EBW machine was augmented from 15kW to 40kW rating, along with additional facilities for chemical cleaning and handling equipment for the higher size and mass. For the NDE, the existing X-ray facility in kV range was augmented to 7.5MeV range. Multiple NDE techniques were employed, which complement each other in ascertaining weld quality, including Time of Flight Diffraction and Dual Linear Array Phased Array Ultrasonic Testing, the team concluded.

Mission Samudrayaan: India inches closer to sending humans into ocean's darkest depths, key details inside
India just got one step closer to sending people deep into the ocean! Scientists have completed a major part of the Samudrayaan project , a human mission to explore the ocean floor, by successfully welding the crew pod of the deep-sea vehicle, Matsya-6000 . What is Samudrayaan? Samudrayaan is India's first manned deep ocean mission, run by the Ministry of Earth Sciences. The goal? To send three people up to 6 kilometres below sea level using a special vehicle that can handle extreme underwater conditions, crushing pressure, cold temperatures, and total darkness.

The most important part of this HOV is a titanium sphere, 2.26 metres wide, with walls 80 mm thick, built to survive pressures of 600 bar and temperatures as low as -3°C. On Wednesday, ISRO (India's space agency) announced that it had successfully welded this titanium pod using Electron Beam Welding (EBW), a first of its kind in India. This welding process was extremely difficult because it needed to join thick titanium parts together with high precision. Live Events Why This Is a Big Deal Welding thick titanium isn't easy. The team had to upgrade their tools, increasing their welding machine's power from 15kW to 40kW, and even build better testing equipment. They carried out nearly 700 test welds, even inserting fake defects to test their safety checks. Finally, they completed a 32-minute-long weld on the actual sub, 80 mm thick over 7.1 metres. It was a continuous process that required pinpoint accuracy. ISRO called it a 'national first in scale and precision.' Now that the weld is done, Matsya-6000 is one step closer to underwater trials. Once ready, it will join an elite group of human submersibles worldwide that can go 6 km deep. This will help India explore new sea life, underwater minerals, and develop cutting-edge tech.

'The existing X-ray testing system, which operated in the kilovolt range, was similarly upgraded to a 7.5 MeV facility to enable deeper inspection. To ensure safety and certification, multiple NDE methods were employed to verify weld quality — including Time of Flight Diffraction (TOFD) and Dual Linear Array Phased Array Ultrasonic Testing (DLA PAUT). 700 trials Nearly 700 welding trials were carried out to fine-tune process parameters. Artificial defects were introduced in test samples to validate and calibrate the inspection techniques. Third-party agencies are reviewing and certifying the welding specifications, qualification protocols and NDE processes. The breakthrough came with the successful completion of the first high-penetration weld on the actual sphere hardware. This involved 80 mm thick welds over a 7,100 mm length, achieved in a continuous 32-minute operation, 'a national first in scale and precision' as per Isro. The milestone marks a significant leap for India's underwater exploration ambitions and brings Matsya-6000 closer to sea trials. Once complete, the vehicle will be among the very few human submersibles in the world capable of reaching such depths, opening new frontiers for deep sea science, resource exploration and technology development.
