Construction of large ships with domestic "medical cored wire"

The welding of the hull structure of a large warship in China was successfully used for the first time in the past. The new type of flux-cored welding material led by Professor Qi Chibin of the Naval Engineering University filled the gap in China.

On the 28th, I learned from the Research Department of Haigong University that the flux-cored wire developed by Professor Gui Chibin from the Department of Naval Architecture of the School of Naval Architecture and Power won the gold medal at the 16th National Invention Exhibition, and also won the new product of the Geneva International Invention Exhibition. New Technology Special Award".

The traditional electrode is a steel-coated steel core that is hand-welded by hand. The flux-cored wire is wrapped with steel, so that it can be wound into a disk for automatic and semi-automatic welding. It is an efficient welding material developed in the 1950s. At present, imported flux-cored wire accounts for half of the market in China. In the high-demand areas of construction of ships, power stations, bridges, etc., it can only rely on imported flux-cored wire.
