Submerged arc welding wire and flux description

With regard to the technical performance of commercial fluxes, the current practice in the industry is that the smelting flux gives its chemical composition and the mechanical properties of the deposited metal with a kind of welding wire. The sintering flux only gives its slag structure and is equipped with a welding wire. The mechanical properties of deposited metal. This seems to be not practical enough. Few users have analyzed the chemical composition of the flux batch by batch, because in addition to the difficulty of the analysis method and equipment, the results are in line with the user's requirements. The submerged arc welding wire and flux are more efficient today. One of the mechanized welding methods, its full name is submerged arc welding wire and flux, also known as automatic arc welding under the flux layer. 

Advantages: The high production efficiency is because, on the one hand, the conductive length of the welding wire is shortened, and the current and current density are increased, so that the arc penetration and the welding efficiency of the welding wire are greatly improved. (In general, the penetration depth of one side of the groove is up to 20mm. On the other hand, due to the heat insulation of the flux and the slag, there is almost no heat radiation on the arc, and there is less splash, although the heat loss for melting the flux is Increased, but the overall thermal efficiency is still greatly increased.
