According to the Shandong Academy of Sciences Wang Juncheng introduced, with the marine engineering and marine resource development to the deep development, the construction of marine structures, installation and maintenance, without exception, need the support of marine welding. The key technology of marine welding "underwater wet welding and cutting" and "large plate welded titanium alloy," in the world, only a very small number of countries to master.

At present, China s marine welding materials and equipment behind, and all dependent on foreign imports, are severely constrained in key technologies. Shandong Academy of Sciences Institute of Marine Instrumentation After three years of technical research, the successful control of these two technologies, and development of the marine environment for 200 meters underwater welding and cutting materials, equipment, breaking the monopoly of foreign technology.

Breakthroughs in related technologies, the Shandong Academy of Sciences is currently working to build China s first complete marine welding technology and equipment industrial base, the new welding materials and equipment into the marine industry. Base will build a welding materials, welding equipment and services to large-scale production capacity, to meet the basic needs of China s current development of marine resources, changes in China s marine equipment, welding materials and long-term dependence on foreign imports.
