摘要

    摘要
  • 摘要: 应用自制微型电容储能电阻焊机分别对AZ91D镁合金以及Cu-40%Co(质量分数)合金箔带进行了微型储能电阻点焊连接,获得了组织健全的连接接头。研究发现,AZ91D/AZ91D镁合金、Cu-Co/Cu-Co合金箔带的点焊接头均由熔核、熔核周围的热影响区、以及由熔核向热影响区过渡的半熔化区(熔合线)组成。镁合金接头具有规则的卵形熔核,而铜合金接头则出现扁平状的熔核。选用如下工艺参数,可获得组织致密的点焊接头。镁合金工艺参数为:焊接能量1.5~2.0 J、焊接电压80 V、电极压力10~20 N;铜合金工艺参数为:焊接能量6.0~8.0 J、焊接电压80 V、电极压力4~8 N。
    Abstract: The connection characteristics of rapid quenched Cu-40wt%Co and AZ91D Mg alloy foils has been studied using a self-developed micro-type energy-storage welding machine. The ideal connecvtion joints have been obtained. The spot welded joints of both AZ91D Mg and Cu 40wt% Co alloy foils are composed of nugget,heat-affected zone. The joint morphology of Mg alloy foils is characterized by a regular ellipsoidal nugget, while those of Cu alloy foils exhibit the flat nugget. To obtain the high quality spot welded joint,the welding parameters are determined as: welding energy 1.5~2.0 J, welding voltage 80 V, and electrode pressure 10~20 N for AZ91D Mg alloy foils; and 6.0~8.0 J; 80~100 V;and 4~8 N for Cu-Co alloy foils respectively.
