摘要
摩擦叠焊(FSW)是一种新型的固相连接技术,英国TWI、德国GKSS研究中心等单位近10多年来在这方面进行了大量的应用基础研究,目前已经具备了商业化工程服务的技术能力。简单介绍了摩擦叠焊的起源、FHPP单元成型机理及FSW焊缝的连接特性,并介绍了欧盟国家的工程化应用研究历程。国外的试验研究结果表明,摩擦叠焊技术在干湿环境条件下都能够获得较好的连接质量,因此在材料的成型加工尤其是钢结构的水下湿式维修方面具有巨大的应用潜力。我国应该优先结合海洋石油工业的实际发展需求,尽快开展相应的应用基础研究工作。
This paper simply introduced the origin of friction stitch welding, the mechanism of friction hydro pillar processing (FHPP) elemental forming process, the bonding properties of FSW. The research process for engineering application in European-Union countries has also been discussed in the paper. The foreign experimental research illustrated that the friction stitch welding can achieve good bonding properties under the condition of dry or wet environment, so it occupies great potentials in the repair of steel structure, especially in the case of underwater repair. The domestic researchers should combine with the practical developmental requirement of national oil industry in priority, to initiate the related basic application research work as soon as possible.
