Risong Technology is continuously committed to the research and development of welding systems for various materials. It has carried out a lot of research and development in the connection of non-ferrous metals, plastics, carbon fibers, dissimilar materials and other materials, and has developed the friction stir welding process, laser welding process, advanced gas shielded welding process, hot plate plastic welding process, and other processes. This system involves the fish scale welding technology for aluminum alloy frames of shared bicycles, and it is able to realize one-time welding in complex weld forms. The appearance quality of welds can be comparable to that of TIG filler wire welding. The system features spatter-free and efficient welding and excellent mechanical properties of welds. It can be widely used in automotive, NEVs, railway-locomotive, shipbuilding, electric power, and other industries.
