India’s First Indigenous Hybrid Laser Arc Welding Technology Developed By Cochin Shipyard And SFO

In a significant boost to India’s advanced manufacturing capabilities, SFO Technologies Pvt. Ltd., the flagship company of NeST Group, and Cochin Shipyard Limited (CSL) have unveiled the country’s first indigenously designed and manufactured Hybrid Laser Arc Welding (HLAW) technology.

The announcement was made at the inauguration of the Advanced Laser Engineering Centre and Hybrid Laser Arc Welding R&D Facility at NeST Hitek Park, Kalamassery. The facility was inaugurated by Shri Jose V. J., Chairman and Managing Director, CSL, and Dr. N. Jehangir, Chairman and Managing Director, SFO Technologies.

Jointly developed by Cochin Shipyard Limited (CSL) and SFO Technologies, the Hybrid Laser Arc Welding (HLAW) system integrates laser welding, conventional arc welding, robotics and advanced automation, powered by a high-power fibre laser source indigenously developed by SFO Technologies. The technology is expected to deliver faster welding speeds, deeper penetration, lower distortion and improved weld consistency across shipbuilding, defence, heavy engineering, railways, energy and other strategic manufacturing sectors like large tanks, wagons etc. for improving productivity.

The development is seen as a step towards reducing India’s dependence on imported laser welding platforms and strengthening domestic capability in high-end industrial technologies. For shipbuilding in particular, where welding is central to vessel construction, the system could help improve productivity, structural quality and manufacturing repeatability.
