埋弧焊工艺由于其易于应用、高电流密度以及同时使用多于一根焊丝存款大量焊接金属的能力而被普遍使用，特别是在磨损部件的修复中，这对制造商来说非常重要。在这项研究中，磨损的零件焊接使用埋弧焊工艺。为此，使用了各种金属丝和焊剂。在不同载荷下对这些焊接件进行了磨损试验，并检查了硬度和显微组织的变化。使用销-盘磨损试验装置。结果表明，最硬的焊缝金属表现出最高的耐磨性，而最硬的焊缝金属表现出最低的耐磨性。焊缝硬度和耐磨性得到被认为是依赖于焊丝和焊剂的化学成分。
The submerged arc welding process is commonly used due to its easy applicability, high current density and its ability to deposit a large amount of weld metal using more than one wire at the same time, especially in restoration of worn parts, which is of great importance to manufacturers. In this study, worn parts were welded using the submerged arc welding process. Various wires and fluxes were used for this purpose. These welded parts were subjected to wear tests under different loads, and changes in the hardness and microstructures were examined. A pin-on-disk wear test apparatus was used. The results showed that the hardest weld metal showed the highest wear resistance, while the least hard weld metal showed the least wear resistance. The weld hardness and wear resistance obtained were found to be dependent on the chemical composition of the weld wire and flux.
