Problems solved by technology

[0003] The existing 5554 aluminum alloy is produced by casting + extrusion, which has low production efficiency and large energy loss, which is not conducive to green and low-carbon requirements
[0004] Produced by the existing 5554 aluminum alloy production process, the product quality is unstable, and the surface quality of the welding wire is not good: there are burrs, cracks, peeling, and scale; the diameter deviation is large
Seriously affect welding quality

Description

technical field [0001] The invention relates to a method for producing gold welding wire, in particular to a method for producing 5554 aluminum alloy welding wire by continuous casting and rolling, and belongs to the field of aluminum alloy welding material processing. Background technique [0002] 5554 aluminum alloy welding wire is mainly used for welding raw materials of aluminum materials. The welding wire is the filler metal for fusion welding methods such as submerged arc automatic welding, electroslag welding, gas shielded welding, and gas welding. The wire melts as the filler metal and fuses with the liquid base metal to form the weld. Conducts welding current and generates an arc to convert electrical energy into heat. When the welding wire is welded, the wire metal accounts for the main part of the entire weld metal, which directly affects the quality and basic performance of the weld. The difference in processing technology and material of the welding wire is re...
