Flux cored wire is a new type of welding material which has been developed rapidly in recent years. It has been widely used in developed countries. According to the data from Japan: since 1985 the proportion of the total welding electrode decreased from 45% to 20%; and the proportion of flux cored wire has reached nearly 30%. In the United States, the proportion of welding rod drops to less than 40%, flux cored wire is close to 40%. In Western Europe, about 30% of the welding rod and about 20% of flux cored wire. Thus, over the past ten years the proportion of traditional industries in developed countries the electrode is declining, while the proportion of flux cored wire in the welding material in it has substantially increased.Flux cored wire and manual electrode has obvious advantages compared with argon arc welding, the welding process is interrupted as continuous production, thereby reducing the number of welded joints, improve the welding quality, improve production efficiency, saving energy.Flux cored wire is also called tubular wire, by type and proportion adjusting cored additives, welding material was easy to design a variety of purposes, because its alloy composition can be flexible and convenient adjustment, so many varieties of flux cored wire is solid wire to smelting and rolling.Flux cored wire is divided into welded and seamless flux cored wire, finished seamless flux cored wire for copper wire, keeping moisture performance and conductivity in the welding process are better than that of seamed flux cored wire.
