摘　　要： 采用均匀化处理-热挤压-拉拔退火-微刮削焊丝制备方法，结合硬度、电导率、拉伸等性能测试和微观组织观察手段，试验优化铝镁锆合金焊丝的生产工艺参数，并成功制备出铝镁锆合金焊丝、、研究结果表明，在470℃保温24h均匀化退火，挤压温度控制在420～430℃，挤压比为50～60，拉拔后中间退火制度为410℃／90min，这样制备出来的铝镁锆合金焊丝表面光亮，质量良好，且焊接性能优异，能满足实际使用要求。 Combining with the means of solidity, conductivity and tensile properties measurement as well as micro- structure observation, the welding wire preparation method of homogenization treatment-hot extrusion-drawing anneals- micro scraping was adopted to test the parameters for optimizing Al-Mg-Zr alloy welding wire production process, and Al- Mg-Zr alloy welding wire was successfully prepared. It shows that the welding wire of bright surface, good quality and excellent welding performance, which meet the requirement for actual use, can be obtained under the conditions of homog- enization treatment at 470℃ for 24 hours, extrusion temperature at 420-430℃, extrusion ratio for 50-60 and intermediate anneals condition after drawing being 410℃/90min.
