Description

technical field [0001] The invention relates to the field of welding wire technology, in particular to an aluminum alloy welding wire containing erbium and ytterbium. Background technique [0002] With the development of welding technology, aluminum and aluminum alloy welded structures have been widely used in civil and military fields, such as various chemical containers, vehicles, ships, aircraft, space probes, rockets, etc. Among them, the welding wire is an important factor affecting the weld metal structure, composition, solid-liquidus temperature, corrosion resistance of the weld, thermal cracking and mechanical properties of the base metal near the seam. The internal quality of aluminum alloy welding wire depends largely on the quality of the original aluminum. In the preparation process of aluminum alloy welding wire, the degassing effect of aluminum alloy melting is not good, which will make the hydrogen content of aluminum alloy welding wire high, resulting in mor...
