堆焊技术广泛应用于材料表面改性和修复行业，具有稀释率低、耐磨性能高等优点。电缆型焊丝（CWW）气体保护焊（GMAW）辅助填充焊丝（AWF）是一种以CWW作为耗材电极的创新堆焊方法。本文研究了稀释率和耐磨性。结果表明：随着焊接电流的增大，AWF-CWW-GMAW堆焊层的熔深增大，这与CWW-GMAW堆焊方法一致；在相同参数下，堆面层的稀释率比CWW-GMAW的稀释率低19%左右。与CWW-GAMW法相比，在相同焊接参数下，AFW-CWW-GAMW法处理的试样堆焊层稀释率小、磨损少、摩擦系数小、硬度高。堆焊层从焊缝到母材的合金元素分布高于CWW-GMAW。
Surfacing technology is widely used in material surface modification and repair industries, with the advantages of low dilution rate and high wear-resistance performance. The assisted wire filling (AWF) of cable-type welding wire (CWW) gas metal arc welding (GMAW) is an innovative surfacing method, using CWW as the consumable electrode. The dilution rate and wear-resistance performance were studied in this paper. The results show that the weld penetration of the AWF-CWW-GMAW surfacing layer increased with the increase of welding current, which was consistent with the method of CWW GMAW. The dilution rate of the surfacing layer was about 19% lower than that of the CWW-GMAW with the same parameters. Comparing with the CWW-GAMW method, the sample treated by AFW-CWW-GAMW had a smaller dilution rate of surfacing layer, a less wear loss, a smaller friction coefficient and a higher hardness under the same welding parameters. The alloy element distribution of the surfacing layer was higher than that of CWW-GMAW from the weld to the base metal.
