摘　　要：主要阐述了应用于混凝土输送泵眼睛板耐磨堆焊焊条的研究。实验中通过对其堆焊焊条工艺性能的研究,得出了在堆焊焊条的药皮中,添加一定量的石墨元素后,堆焊金属的焊缝处所具有的耐磨性和硬度都能够大幅显著提升,夹渣少易脱渣,同时焊道处仅有少量微渣存在,多道多层堆焊时就不必清渣,这样既能保证零件的工作效率,又能延长其使用寿命,还能取得较好的经济效益,达到了预期效果。A wear resistant surfacing welding electrode for concrete pump eye plate and the processing property were studied. The results show that the wear resistant and hardness can greatly improve after adding a certain percentage of graphite into the electrode coating. The detachability of the slag on the electrode is easy and the slag inclusion is less, the welding seam has only less tiny slag. So the multi-weld layer and multi-weld seam does not need to remove the slag. Such not only ensure the efficiency of the parts, but also extend its useful life. The excellent economic benefits were obtained ,which can realize the expected effect.
