The formula of flux cored welding wire mainly includes various metal powders and chemical substances, which play a key role in the manufacturing process of the welding wire to ensure the quality and performance of the weld seam. The formula design of flux cored welding wire involves multiple elements and compounds, aiming to improve the wear resistance, strength, toughness, and heat resistance of the weld seam. Here are some common formulations and functions of flux cored wire: Deoxidizer and Denitrifier: In order to purify the filler metal and prevent the formation of pores or embrittlement in the weld metal, strong deoxidizers such as Al powder and weak deoxidizers such as manganese and silicon need to be added to the flux. Self protective flux cored welding wire also requires the addition of AL as a nitrogen removal agent. Welding slag forming agent: Calcium, potassium, sodium and other silicate substances are used as welding slag (slag) forming agents, which can effectively protect the molten pool from atmospheric pollution when added to the flux, while also making the weld appearance good and cooling quickly. Arc stabilizer: Sodium and potassium can keep the arc soft and smooth, reduce splashing, and help stabilize the welding process. Alloy elements: Adding alloy elements such as manganese, silicon, molybdenum, chromium, carbon, nickel, We can make wire drawing machine.FCW strip forming machine Layer winding machine,drum packing machine.
