摘要：
一种稀土镁合金焊丝材料，其特征在于该材料的合金元素组成及其重量配比如下：Y为2.2～12.4％，Zn为1.5～5.5％，Zr为0.2～0.95％，Si≤0.02％，Cu≤0.03％，Fe≤0.01％，Ni≤0.007％，杂质总含量≤0.30％。本发明还公开了该稀土镁合金焊丝材料的制备方法。与现有技术相比，本发明的优点在于：获得的稀土镁合金焊丝材料大大提高了稀土镁合金的焊接强度，并有利于稀土镁合金的应用。
摘要（英）：

The invention discloses a rare-earth magnesium alloy welding wire material. The rare-earth magnesium alloy welding wire material is characterized by consisting of the following alloy elements in percentage by weight: 2.2-12.4% of Y, 1.5-5.5% of Zn, 0.2-0.95% of Zr, less than or equal to 0.02% of Si, less than or equal to 0.03% of Cu, less than or equal to 0.01% of Fe, less than or equal to 0.007% of Ni and less than or equal to 0.30% of impurities. The invention further discloses a preparation method for the rare-earth magnesium alloy welding wire material. Compared with the prior art, the obtained rare-earth magnesium alloy welding wire material greatly improves welding strength of the rare-earth magnesium alloy, and is beneficial for application of the rare-earth magnesium alloy.
