Description

technical field [0001] The invention relates to the technical field of welding wire processing, in particular to an aluminum-erbium alloy welding wire and a preparation method thereof. Background technique [0002] Welding wire is used as filler metal or as conductive wire welding material at the same time. In gas welding and gas tungsten arc welding, the welding wire is used as filler metal; in submerged arc welding, electroslag welding and other gas shielded arc welding , the welding wire is not only a filler metal, but also a conductive electrode. The surface of the welding wire is not coated with anti-oxidation flux. Most welding wires belong to this category, including carbon steel welding wire, low alloy structural steel welding wire, alloy structural steel welding wire, stainless steel welding wire and non-ferrous welding wire. Metal welding wire, etc. [0003] The performance and quality of the welding junction of the existing alloy welding wire are insufficient dur...
