激光修复中的若干关键问题及常用检测技术

SEVERAL KEY POBLEMS AND COMMON DETECTION TECHNIQUES IN LASER REPAIR

  • 摘要: 作为金属增材制造的重要分支,激光修复是装备再制造等战略性新兴产业的核心技术之一。激光修复技术的突破与其在航空航天、国防装备等关键领域的应用,契合国家的战略需求,受到众多研究者的关注。相关研究结果表明,激光制造过程复杂、环境极端,其中应力、应变场的演化影响了修复体的缺陷分布和几何构型,是决定修复质量的关键因素。此种背景下,传统检测方法和技术难以直接应用于激光修复工程中,迫切需要发展适用于激光修复工程的检测技术。目前,与修复制造设备相匹配的测量手段匮乏,对此本文开展了激光修复中的关键问题及常用检测技术的调研研究。

     

    Abstract: As an important branch of metal additive manufacturing(AM), laser repair is one of the core technologies in strategic emerging industries such as equipment remanufacturing. The breakthrough of laser repair technology and its application in key fields such as aerospace and national defense equipment are in line with the strategic needs of the country and have attracted the attention of many researchers. The results show that the laser manufacturing process is complex and the environment is extreme, and the evolution of stress and strain field affects the defect distribution and geometry of the restoration, which is the key factor to determine the repair quality. Under this background, traditional detection methods and technologies are difficult to be directly applied to laser repair engineering, so it is urgent to develop detection technologies suitable for laser repair engineering. At present, there is a shortage of measuring means to match the repair manufacturing equipment, so the key problems and common detection techniques in laser repair are investigated and studied in this paper.
