摘要
通过D6 6 7焊条堆焊试样 ,同时用CO2 焊丝堆焊试样 ,然后把这些试样分别做显微硬度试验、金相试验、磨损试验。通过分析比较试验结果发现 :用药芯焊丝堆焊试样的硬度高于用D6 6 7焊条堆焊试样硬度 ,但D6 6 7焊条堆焊试样的磨损性比药芯焊丝堆焊试样的好。同时 。
From the results of micro hardness testing,metallography testing,wearablity testing of the samples of overlaying with electrode D667 and CO 2 welding wire,we can find that the hardness of the sample with flux cored wire is higher than that of electrode D667,but the wearability of the sample with electrode D667 is better than that of flux cored wire. Meanwhile the characteristics and ingredients of the sample bond are analysed in the article.
