Abstract

The invention relates to the technical field of welding materials, in particular to a stainless steel welding wire and a preparation method thereof. The stainless steel welding wire consists of a flux core and a stainless steel strip for wrapping the flux core; the flux core accounts for 25-35% of the total weight of the stainless steel welding wire; and the flux core contains the following components in percentage by weight: 40-50% of Ti or TiO2, 10-20% of Si or SiO2, 10-20% of Mn, 10-15% of KBF4, 5-10% of Nb, 5-8% of Mo, 3-5% of Mg or MgO, 1-2% of N, and the balance of Al or Fe. The stainless steel welding wire, provided by the invention, applies a flux-cored wire to melt and weld a particle reinforced composite material, can conveniently adjust the components and the filling rate of wrapped powder according to different welding requirements, and has the advantages of high strength and fatigue resistance.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a stainless steel welding wire and a preparation method thereof. Background technique [0002] Stainless steel welding wire and its preparation method can be divided into stainless steel solid welding wire and stainless steel flux cored welding wire, among which stainless steel flux cored welding wire can be used for welding stainless steel easily and efficiently like carbon steel and low alloy steel flux cored welding wire, stainless steel flux cored welding wire The application of welding wire is mainly based on MAG welding. Compared with manual welding, it can increase the deposition speed; it has a wide range of adaptation to current and voltage, and it is easier to set welding conditions, and it is easy to perform semi-automatic and automatic welding. It has extremely important application value and broad application prospects in the fields of electrical appliances...
