Abstract
The invention discloses a welding wire for low alloy steel. The welding wire is prepared from components as follows: C, Si, Cu, Mg, Nb, Al, K, Mn, Ni, Cr, Ti, Sr, Mo, V, Nd, Ce and the balance of Fe and inevitable impurities. The welding wire for low alloy steel has good welding performance, during welding, electric arc is stable, small splashing is produced, welding fluid liquidity is good, the weld surface is uniformly covered with welding slag, so that interfacial tension of the welding slag and deposited metal is increased, slag detachability is improved, formation of the obtained weld is good, the weld surface is free of cracks and pores, and the deposited metal has good mechanical properties.
Description
Technical field [0001] The invention relates to the technical field of metal materials, in particular to a welding wire for low alloy steel. Background technique [0002] Low alloy steel has good weldability, excellent formability and low manufacturing cost, so it is widely used in the fields of containers, bridges, construction, engineering machinery, ships, vehicles and aerospace. When traditional welding wire is welding low-alloy steel, the slag is firmly bonded to the weld, which makes it very difficult to clean and smooth the weld slag, and the weld shape is poor. Furthermore, after cleaning the slag and grinding, the welding The seam is still rough and uneven, and the mechanical properties of the deposited metal are not ideal. These have affected the quality of low alloy steel. Summary of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes a welding wire for low alloy steel, which has good welding performanc...
