船舶增材制造的认可与船级社标准分析

Approval of Additive Manufacturing for Ships and Analysis of Classification Society Standards

增材制造技术在各行业的发展趋于成熟,船舶领域方面的应用发展也有了广泛进展。针对船舶领域的增材制造应用,分析研究了目前船舶领域应用中主流的粉末床熔融、定向能量沉积和电弧熔丝沉积的技术原理、技术应用、设计评估、认可和检验。重点分析了中国船级社《增材制造检验指南》部分典型船用产品增材制造技术与认可检验流程,以及增材修复工艺认可流程,研究验证了标准体系对船舶增材制造技术的必要性。

The development of the additive manufacturing technology in various industries tends to be mature,and the applica⁃tion development in the field of ships has also made extensive progress.For the application of additive manufacturing in the ship⁃building field,the technical principles,technical applications,design evaluation,approval and inspection of the powder bed fu⁃sion,directed energy deposition,and wire arc additive manufacture used in the marine field.The necessity of the standard sys⁃tem in ship additive manufacturing technology is verified through the analysis and research of the CCS Inspection Guidelines for Additive Manufacturing and the new standard being compiled by the International Association of Classification Societies(IACS).
