Selecting welding consumables to get satisfactory results in hard facing weld repair jobs at a low cost is an important consideration. The standard martensitic welding electrodes used for hardfacing are expensive, so an investigation into finding suitable substitutes is a worthwhile activity. The objective of this study was to analyze the hardfacing deposits on using a low carbon steel welding electrode with metal powders added to the weld pool. Four different samples were hardfaced applying a submerged arc welding setup with constant heat input. Single and three layers of hardfacing samples were welded using a standard martensitic electrode and compared to using low carbon steel electrodes with added metal powders. An optical emission spectrometer was used to obtain the chemical compositions of welded metal layers. A scanning electron microscope was used to characterize the metallurgical structures of deposits. SEM images of worn surfaces were also obtained. Microhardnessand ab...

马氏体表面堆焊合金中添加金属粉末对其耐磨性的有效性

一个重要的考虑是选择焊接材料以低成本获得在堆焊工作中令人满意的结果。用于表面硬化的标准马氏体焊接电极价格昂贵，因此研究寻找合适的替代品是一项值得开展的活动。这项研究的目的是分析使用低碳钢焊条并在焊缝中添加金属粉末的情况下的堆焊层。使用具有恒定热量输入的埋弧焊装置对四个不同的样品进行了硬面处理。使用标准马氏体焊条焊接单层和三层表面堆焊样品，并与使用添加了金属粉末的低碳钢焊条进行比较。使用光发射光谱仪获得焊接金属层的化学成分。使用扫描电子显微镜表征沉积物的冶金结构。还获得了磨损表面的SEM图像。显微硬度和硬度
