摘要

本工作旨在研究先进超超临界（AUSC）锅炉用合金617和P92钢的异种屏蔽金属电弧焊（SMAW）接头的组织和力学性能。SMAW接头使用三种不同类型的电极生产，即ENiCrFe-3、ENiCrMo-3和ENiCrCoMo-1。在焊接接头的微观结构观察过程中，未在焊件中检测到可能的裂纹。使用ENiCrCoMo-1电极获得的异种金属焊缝（DMW）显示出最大的抗拉强度，而ENiCrFe-3电极获得了最小的抗拉强度。在所有电极中，ENiCrFe-3电极表现出最大的冲击韧性，而ENiCrCoMo-1电极表现出最小的冲击韧性。根据显微组织和力学性能，选择ENiCrFe-3电极作为生产617合金和P92钢DMW的最佳电极。

Selection of Electrode Material for Inconel 617/P92 Steel SMAW Dissimilar Welds

The present work aimed to investigate the microstructure and mechanical properties of the dissimilar shielded metal arc welded (SMAW) joint of Alloy 617 and P92 steel for advanced ultra-supercritical (AUSC) boilers. The SMAW joint was produced using three different types of electrodes, namely ENiCrFe-3, ENiCrMo-3 and ENiCrCoMo-1. During microstructural observation of the welded joints, no possible cracking was detected in the weldments. The dissimilar metal welds (DMWs) obtained using the ENiCrCoMo-1 electrode showed the maximum tensile strength, while the minimum was obtained for the ENiCrFe-3 electrode. Among all the electrodes, the ENiCrFe-3 electrode exhibited the maximum impact toughness, while the minimum was obtained for ENiCrCoMo-1 electrodes. Based on microstructure and mechanical characterization, the ENiCrFe-3 electrode was selected as the best one among all to produce the DMW of Alloy 617 and P92 steel.
