Abstract

The application of wire arc additive manufacturing (WAAM) in manufacturing has raised interest among researchers. In this paper, the introduction of additive manufacturing and wire arc additive manufacturing, various heat resources for WAAM, aluminium alloys, aluminium alloys ER4043, and performance evaluation of WAAM of ER4043 have been discussed in detail based on bead geometry, microstructure, microhardness, and tensile properties as well as the building path strategies, problems, and future directions. Based on this review, aluminium alloy 4043 (ER4043) is an Al-Si alloy frequently employed as a filler wire because it has superior fluidity and significantly fewer flaws in additively built structures. Next, dwell time and cooling efficiency during the WAAM process significantly affect bead geometry. Besides, a finer microstructure can be obtained with a better cooling rate. However, a coarser microstructure is obtained along with the increased deposition height due to heat accumulation and low solidification rate. Heat input is identified as the main cause of porosity, and CMT with a lower heat input is preferable and outperformed GTAW and GMAW in terms of mechanical properties.

ER4043铝合金丝弧增材制造工艺及热源研究进展

电弧增材制造(WAAM)在制造业中的应用引起了研究人员的兴趣。本文从焊头几何形状、微观结构、显微硬度、拉伸性能等方面对增材制造和电弧增材制造的介绍、WAAM的各种热源、铝合金、ER4043铝合金、ER4043 WAAM的性能评价以及构建路径策略、存在的问题和未来发展方向进行了详细的讨论。基于这一综述，铝合金4043 (ER4043)是一种铝硅合金，经常被用作填充线，因为它具有优越的流动性和明显较少的缺陷，在增材结构中。其次，保温时间和冷却效率在WAAM过程中显著影响珠的几何形状。此外，在较好的冷却速率下，可以获得较细的组织。然而，由于热积累和低凝固速率，随着沉积高度的增加，获得了粗糙的组织。热输入是孔隙的主要原因，低热输入的CMT在力学性能上优于GTAW和GMAW。

期刊介绍： The Journal of Mechanical Engineering & Sciences "JMES" (ISSN (Print): 2289-4659; e-ISSN: 2231-8380) is an open access peer-review journal (Indexed by Emerging Source Citation Index (ESCI), WOS; SCOPUS Index (Elsevier); EBSCOhost; Index Copernicus; Ulrichsweb, DOAJ, Google Scholar) which publishes original and review articles that advance the understanding of both the fundamentals of engineering science and its application to the solution of challenges and problems in mechanical engineering systems, machines and components. It is particularly concerned with the demonstration of engineering science solutions to specific industrial problems. Original contributions providing insight into the use of analytical, computational modeling, structural mechanics, metal forming, behavior and application of advanced materials, impact mechanics, strain localization and other effects of nonlinearity, fluid mechanics, robotics, tribology, thermodynamics, and materials processing generally from the core of the journal contents are encouraged. Only original, innovative and novel papers will be considered for publication in the JMES. The authors are required to confirm that their paper has not been submitted to any other journal in English or any other language. The JMES welcome contributions from all who wishes to report on new developments and latest findings in mechanical engineering.
