    Microstructure and Tensile Strength of Rust-Proof Aluminum Plate and Zinc-Coated Steel Plates Braze-Weld Joint Prepared by Cold Metal Transfer

      摘要
    • 摘要: 采用冷金属过渡(CMT)熔钎焊接工艺, 对LF21防锈铝板和DD51D+Z镀锌钢板进行了异种金属的连接, 对接头的显微组织和抗拉强度进行了研究。结果表明: 防锈铝板和镀锌钢板的熔钎焊接头的中间界面区化合物为4~6 μm厚的FeAl3金属间化合物, 接头的平均横向抗拉强度为77 MPa, 接头的强度系数为0.6。

       

      Abstract: The cold metal transfer (CMT) brazing-welding process was used to weld dissimilar metals of LF21 rust-proof aluminum plate and DD51D+Z zinc-coated steel plate, and the microstructure and tensile strength of the joint were studied. The results show that the compound layer of middle interface zone of the braze-weld joint was intermetallic compound FeAl3 with thickness of 4-6 μm. The average transverse tensile strength of the joint was up to 77 MPa and strength coefficient was 0.6.
