Abstract
A high-strength welding wire includes, in weight percentage, 5.8% Cu, 0.2% Mn, 0.1% V, 0.2% Zr, 0.2% Si, 0.3% Fe, 0.1% Zn, 1.4% compensation element, 0.2% hydrogen evolution element, 1.2% nanoceramic particle, and Al for the balance. Various powdered raw materials are mixed, wrapped with an aluminum strip, rolled and subjected to wiredrawing to form the high-strength welding wire. In a welding method for the high-strength welding wire, a K-shaped groove is formed between a stringer and a panel, and an inclined angle of the welding gun and a distance between the welding gun and the weld are adjusted. Then the angle between the wire-feeding tube and the welding gun and the striking mechanism and the weld are adjusted. Protective gas is supplied to the welding pool, and a laser is activated to perform welding. A striking mechanism is started to strike the weld.
