摘要
利用光学显微镜和扫描电镜对用5B06-O合金焊丝焊接后产生的焊缝表面缺陷进行了分析;确认焊缝表面的夹杂物为MgO焊渣,其产生原因是焊接时保护气体流量不足或焊接现场环境不好造成的。
The surface blemish at the joint after using 5B06-O welding wire was developed. The part surface was analyzed by SEM and so on. The admixture is confirmed MgO at the surface of the welding wire. The reason of the MgO is that there is not enough protection air or the bad environment.
