A common type of sintered flux used in submerged arc welding. The model is SJ101Another is smelting flux. HJ431 is commonly used
Sintered flux is a kind of high quality, high efficiency, energy saving and environmental friendly flux. The welding flux is smokeless, tasteless, arc free and without spatter when welding. The manufacturing process has no environmental pollution, low energy consumption, the use of raw materials. The preparation of scientific spirit full of sintered flux, welding process, strong adaptability, can be used for welding of thin plate, angle weld and super standard, high speed, multi wire, anti blowhole, narrow gap, deep groove under various working conditions, good slag detachability, weld good forming. Most of the sintered flux products are spherical and granular, which facilitates the delivery and recycling of solder flux in the welding process.
Sintered flux refers to third substances used to reduce the interfacial tension between the base metal and the filler metal.Sintered flux is a granular welding material. When welding, it can melt to form molten slag and gas, which can protect and metallurgical molten pool. A substance that is capable of melting to form molten slag and gases when welding and to protect and treat molten metals. Submerged arc welding flux for submerged arc welding.Extension of knowledge point:The functional part of the sintered flux can be divided into three:1. Remove the oxide of welding surface, reduce the melting point and surface tension of solder, and reach the brazing temperature as soon as possible;2. Protect the weld metal from the harmful gases in the surrounding air when it is in liquid state;3 make the liquid solder have proper flow velocity to fill the brazing seam.
