Development of a High-toughness Self-shielded Flux-cored Wire

    摘要
  • 摘要: 采用正交设计方法。研制出一种新型氟钙钛渣系(GaF2-TiO2-MgO)的自保护药芯焊丝,其焊接工艺性能良好,烟雾少,并且熔敷金属组织均匀、细小,塑性和低温韧性高,是与550MPa级低合金高强钢相匹配的一种高效焊接材料,适于野外焊接重要结构。

     

    Abstract: By means of orthogonal besign method, a new self-shielded flux-cored wire with CaF2-TiO2-MgO slag system has been developed. The deposited metal of the wire is characterized by its high ductility and low-temperature toughness, refined microstructure and good technological properties in welding. It is a quality welding consumable matching the HSLA steel with 550 MPa strength level and suitable for welding important constructions.
