To address the problem of mutual constraints between heat input and efficiency in arc additive manufacturing, a BCTW-GIA process is proposed. In this paper, components are manufactured using the BCTW-GIA and T-DW methods. The macroscopic morphology, cooling process, microstructure and properties of the components are analysed. According to the results, the BCTW-GIA method achieves a deposition efficiency of 15.46 kg/h, which is a 123% improvement compared to the T-DW method. The addition of the main wire in the BCTW-GIA method consumed some of the heat, resulting in less heat being applied to the member, and the maximum and average temperatures were reduced by 26% and 13%, respectively, compared to the T-DW method. The BCTW-GIA components have a finer grain size and an average microhardness of 197.17 HV. The BCTW-GIA specimens had higher transverse and longitudinal tensile strengths, which increased by 7% and 10% respectively over the T-DW specimens. [ABSTRACT FROM AUTHOR] |
