“…This is because when the distance between the fiber optic filaments is small, the laser beam acts on the surface of the molten pool. The shock wave generated by the pulsed laser changes the flow direction of the molten metal in the molten pool [ 25 ], stirring the molten pool and increasing the depth-to-width ratio of the molten pool. However, this phenomenon is obvious only when the laser beam acts on the center of the molten pool (s = 0 mm), but not significant when the laser beam acts on the rear of the molten pool.…”

“…Fan et al [ 24 ] carried out a study about improvement of mechanical properties Fe–Cr–C cladded layer by AW-LSF process. Zhang et al [ 25 ] accurately determine the laser forging area through multiple physics melt pool simulation and also studied the flow of molten metal, and the results showed that the high sulfur content introduced by the filled metal transfer had a significant impact on the distribution of Marangoni stress, thereby changing the flow pattern of molten metal. However, as for investigation on AW-LSF for aluminum alloy, research about repairment or remanufacturing by AW-LSF technology, has not yet been reported.…”

Arc-based additive additive technology, like other additive manufacturing technologies such as laser cladding, cold spraying, has been used in repairing metal parts that suffer harsh working conditions, including wear, corrosion, and breaking which prevent them from realising an economic development route when lifespan is extended. However, there is a limitation in the existing study of arc-based additive repair technology. against the backdrop of the rapid development of many emerging technologies, such as artificial intelligence. Hence, this paper aims to provide a holistic status quo of arc-based additive repairing technology (AAR) which includes five sections: Firstly, AAR is overviewed and then followed by types of AAR that provide an understanding of explicit AAR technique, such as powder plasma arc welding, plasma-transfer arc welding, gas metal arc welding, and gas tungsten arc welding. Secondly, parameters optimization characteristics and performance improvement measures related to arc energy density, shielding gas flow rate, tool path, and additional energy field are presented. Thirdly, defects and enhancing methods, including inner gas porosity, distortion and deformation, and cracks and corresponding addressing approaches, are discussed. Finally, challenges like efficiency and complexity of processes, defect control and quality assurance, and process displacement and geometric accuracy are concluded, and trends of AAR are proposed. Through this review, a new picture of the current state of AAR research unfolds that expect to inspire a sight-clear future.
