## About

Based in Shanghai, China and founded in 2020, Shanghai Shengshi Weisheng Technology Co., Ltd., dba 3S Robotics, focuses on the development of intelligent welding technology. The company independently develops intelligent robots with an "AI+3D+ROBOT" system, creating a series of specialized intelligent robots for specific fields (welding, grinding, assembly, etc.) to address the pain point of insufficient automation flexibility in manufacturing. In April 2026, 3S Robotics closed Series A+ funding from HDHyundai Robotics Co., Ltd, Welight Capital and HSG.

The firm specializes in the development and manufacturing of intelligent welding robots, particularly their flagship product, the 3S intelligent welding robot. This advanced machine is engineered to enable users to achieve precision welding without the need for traditional teaching programming methods, operating instead on a 'seeing is welding' principle powered by visual technology. 

The company generates revenue from the sales of intelligent welding robots to B2B clients, including manufacturers and industrial automation companies.
