| Abstract | 试验研究了额定功率为3kW的连续波Nd：YAG激光焊接热输入对激光焊接K418与42CrMo异种金属焊缝形貌的影响。通过光学显微镜、扫描电镜、能谱分析仪、硬度仪、万能试验机及X衍射对激光焊接K418与42CrMo异种金属焊缝接头组织、元素分布、相组成及接头的力学性能进行分析。结果表明，在焊接热输入恒定的条件下，高功率、高焊速的匙孔焊接比低功率、低焊速的热传导焊接更能增加焊缝熔深。通过扫描电镜在焊缝区域观察到了颗粒状物和针状物，能谱分析表明，颗粒状物Nb，Ti，Mo元素聚集，Fe，Ni元素减少；针状物Ti，Nb元素聚集。K418与42CrMo异种金属激光焊接工艺参数优化后的焊缝抗拉强度高于42CrMo母材。 |
