Manufacturing and maintenance procedures in the railway industry regularly implement welding and metal deposition operations to produce joints, coatings and repair structures. During these processes, residual stresses arise through the generation of heat affected zones and plastic deformation. This makes accurate measurements of the internal stresses a critical aspect of manufacturing, monitoring, repair and model validation in the develop new metallic coating and joining technologies. Selection of an appropriate residual stress measurement method has many important factors including component size, resolution and the magnitude and location of internal stresses, often resulting in a combination of techniques required to obtain complete assessment of the stress state. This paper offers a review of residual stress measurement techniques for railway components including rail joints and coatings through comparison of destructive and non-destructive approaches, their measurement capabilities, benefits and limitations. A comprehensive discussion of different applications is provided with a summary of facilities available to both research and industry.
铁路行业的制造和维护程序经常进行焊接和金属熔敷操作，以制造接头、涂层和修复结构。在这些过程中，由于热影响区的产生和塑性变形会产生残余应力。这使得精确测量内部应力成为开发新型金属涂层和连接技术过程中制造、监测、修复和模型验证的关键环节。选择合适的残余应力测量方法有许多重要因素，包括部件尺寸、分辨率以及内部应力的大小和位置，这通常需要结合多种技术才能全面评估应力状态。本文通过比较破坏性和非破坏性方法、它们的测量能力、优点和局限性，对铁路部件（包括钢轨接头和涂层）的残余应力测量技术进行了综述。文中还对不同应用进行了全面讨论，并总结了可供研究机构和行业使用的设施。
