    摘要
  • 摘要: 为了研究CO2激光-熔化极活性气体保护焊（MAG）复合焊接性能，采用CO2激光和CO2激光-MAG复合焊接590MPa级高强度钢，对其焊接接头的显微组织和力学性能进行了研究.结果表明，激光-MAG复合焊接的焊缝金属中，MAG电弧作用区主要为珠光体和贝氏体，激光作用区主要为马氏体；激光-MAG复合焊接的焊缝金属中Mo和Mn合金元素的分布具有不均匀性；激光和激光-MAG复合焊接的试件焊接接头拉伸性能完全满足要求，焊缝强度高于基体强度；激光-电弧复合焊缝金属在-60℃～+15℃试验温度范围内的冲击韧性比激光焊缝金属高；激光-MAG复合焊接焊缝金属硬度在250～400 HV之间，高于基体金属的硬度.
    Abstract: Performance of 590 MPa grade high strength steel weld made by CO2 laser welding and CO2 laser-MAG hybrid welding was investigated. For CO2 laser-MAG hybrid welds, the weld metal in the arc zone mainly consisted of bainite and pearlite, while that in the laser zone was mainly composed of martensite. The distribution of Mn and Mo elements was inhomogeneous in laser-MAG hybrid weld metal. The tensile test of laser welded joint and laser-MAG hybrid welded joints meet the requirements, and the strength of the weld was higher than that of base metal. The hybrid weld metal showed higher toughness than the laser weld metal at test temperature range of -60℃ to +15℃. The hardness of hybrid weld metal was between 250 HV and 400 HV, higher than that of the base metal.
