Stainless steel flux cored welding wire

Pure COZ or COz-I-Ar gas is usually used as the protective gas. The main difference from ordinary gas metal arc welding is that the welding wire contains a flux mixture inside. During welding, the molten flux material, welding wire metal, base metal, and shielding gas under the action of arc heat undergo metallurgical reactions with each other, forming a thin layer of liquid slag to cover the molten droplets and the molten pool, providing another layer of protection for the molten metal.

Flux cored wire arc welding can be used for both semi-automatic and automatic welding, but is typically used for semi-automatic welding. Different welding wires and shielding gases can be used in combination for flat welding, overhead welding, and all position welding. Compared with ordinary gas metal arc welding, shorter wire extension length and larger welding current can be used. Compared with manual arc welding, welding fillet welds can obtain welds with larger fillet sizes. This welding method is commonly used for welding carbon steel, low alloy steel, stainless steel, and cast iron. Due to the above characteristics, this method is a promising alternative to conventional manual arc welding for automated and semi-automatic welding in the era of welding steel. The flux cored wire sheath is made of low-carbon steel or low-alloy steel.
