Welding wire linear stabilizing method for manufacturing aluminum-magnesium alloy welding wire and aluminum-magnesium alloy welding wire prepared through welding wire linear stabilizing method

The invention belongs to the technical field of aluminum alloy welding wires, and relates to a welding wire linear stabilizing method for manufacturing an aluminum magnesium alloy welding wire and the aluminum magnesium alloy welding wire prepared through the welding wire linear stabilizing method. The welding wire linear stabilization method comprises the following steps that step annealing is conducted on an aluminum magnesium alloy welding wire finished product, the annealing temperature ranges from 50 DEG C to 135 DEG C, heat preservation is conducted for 3-24 hours at the annealing temperature, and the specification of the aluminum magnesium alloy welding wire finished product ranges from phi 0.8 mm to phi 2.0 mm. The aluminum magnesium alloy welding wire finished product with the outer diameter dimensional tolerance meeting the welding requirement is treated through the low-temperature stepped annealing process, the internal structure of the material is stabilized, and the performance of the welding wir
