As the carbon dioxide gas shielded arc welding with a clear, good quality welding, to the all-position Welding Supplies , soldering, low cost, high efficiency of production, so get to promote, so that gas-shielded welding wire have also been actively developed. As the flux-cored wire with excellent performance, process performance and good, so common in foreign countries has been applied and fast development. China's carbon dioxide gas shielded welding wire only H08MnSi and H08Mn2SiA and a small amount of solid welding wire (such as ER70S-2 and ER70S-6). Domestic wire problems are more concentrated in the coating, coil, bent hard, joints and uneven areas in diameter. Coating is not good, one poor rust, easy storage; the second is out of copper conductive effects, especially easy to plug the spring tube to increase the wire resistance, and cause arc instability.

At present, solid wires there are dozens of manufacturers, the shipbuilding industry to be based on nearly 10 years of usage, select the number of stable quality, good performance of the wire manufacturing plant, to enhance the quality of contact and timely feedback and advice on performance improvement, improve the welding quality, in order to better build export vessels. In addition, flux cored wire, domestic production has not yet formed a certain scale, flux-cored shipbuilding industry is still a lot of imports. It is understood that there are other domestic manufacturer to introduce flux-cored wire production line, which greatly accelerated the process of flux cored wire localization.

Carbon dioxide gas shielded arc welding shipbuilding industry promotion, the main problem is the use of imported carbon dioxide gas protection welding machine, welding wire, its high price, and spend a lot of foreign exchange; and the use of domestic carbon dioxide gas shielded arc welding equipment, Aluminium Welding Wires, its quality of instability, it is difficult meet the demand. But this is temporary difficulties, if by the shipbuilding industry and welding materials factory together to continuously improve the quality of wire, to further meet the needs of the construction of the export of ships, will in the shortest period of time up to and beyond the level of imports of flux-cored wire. To this end, we want efficient welding technology in the shipbuilding industry under the leadership of the Steering Group to carry out a planned, step by step made ??flux-cored wire technology research, the prospects will be made ??flux-cored wire is excellent.
