In order to improve the welding quality of ship, flexible welding robot system is used to weld nickel alloy valve disc. High efficiency and high quality robot welding system is designed, SNCrW stainless steel welding technology is studied, and test samples are analyzed. After the inspection, there is no size more than 0.06mm defect, it is fully in line with the valve disc quality testing standards that belongs to qualified products, and the first domestic high quality nickel based hardfacing layer metal valve disc welding is perfomed.%为了提高船舶焊接质量,采用机器人柔性化焊接系统堆焊镍合金阀盘.设计了高效、高质量的机器人焊接系统,对SNCrW不锈钢进行了焊接工艺研究,并对样件进行了检验分析.经检验,不存在超过0.06mm的缺陷,完全符合阀盘质量检测标准,属于合格产品,完成了国内首个高质量镍基堆焊阀盘的焊接.
