摘要
不锈钢药芯焊丝堆焊(FCAW)具有效率高、电流电压适应性强、焊缝质量高等优点。介绍了不锈钢药芯焊丝堆焊工艺,经大量工艺试验,确定了为获得良好堆焊层性能的最佳工艺参数,通过焊接工艺评定证实,所选堆焊材料及堆焊工艺正确合理,其各项性能指标均满足有关技术条件要求。配以简易工装,实现了接管内壁及法兰密封面(槽)的自动堆焊,提高了效率,降低了成本。
The FCAW technique with high efficiency,wide adaption and good quality in introduced in this paper.The best techniuque parameters for good surfacing welding performance are given by the experiments.Optimum welding consumable,surfacing welding technique, and their performance index are satistied for the welding requirements by WPS.Automatic surfacing welding for the inner welding of tube and flange sealing cover it, pressure vessel is available.
