Abstract

In the field of metallic additive manufacturing, Selective Laser Melting (SLM) has become a predominant technology due to its advantages of short production cycles, high precision, and low cost. It is frequently employed in the production of complex parts. This paper proposes the use of a scanning laser line source, in conjunction with the singular value decomposition method, to reconstruct phase space and identify surface cracks in SLM specimens. The scanning laser line source addresses the limitations of a single line source, which is often unable to accurately detect tiny cracks. By comparing experimental and simulation data, the results demonstrate that the scanning laser line source can effectively compensate for some of the detection deficiencies of a single line source.

利用激光产生的超声波技术和相空间重构技术检测选择性激光熔化印花铬镍铁合金 718 的表面裂纹

在金属增材制造领域，选择性激光熔融技术（SLM）因其生产周期短、精度高、成本低等优势，已成为一种主流技术。它经常被用于复杂零件的生产。本文提出使用扫描激光线光源，结合奇异值分解法，重建相空间并识别 SLM 试样中的表面裂纹。扫描激光线光源解决了单线光源通常无法准确检测微小裂纹的局限性。通过比较实验和模拟数据，结果表明扫描激光线光源可以有效弥补单线光源在检测方面的一些不足。

期刊介绍： Measurement Science and Technology publishes articles on new measurement techniques and associated instrumentation. Papers that describe experiments must represent an advance in measurement science or measurement technique rather than the application of established experimental technique. Bearing in mind the multidisciplinary nature of the journal, authors must provide an introduction to their work that makes clear the novelty, significance, broader relevance of their work in a measurement context and relevance to the readership of Measurement Science and Technology. All submitted articles should contain consideration of the uncertainty, precision and/or accuracy of the measurements presented. Subject coverage includes the theory, practice and application of measurement in physics, chemistry, engineering and the environmental and life sciences from inception to commercial exploitation. Publications in the journal should emphasize the novelty of reported methods, characterize them and demonstrate their performance using examples or applications.
