...Xiao Fan Zhao; Andreas Wimmer; Michael F. Zaeh Purpose The purpose of this paper is to demonstrate the impact of the welding sequence on the substrate plate distortion during the wire and arc additive manufacturing (WAAM) process. This paper also aims to show the capability of finite element...

...Runyao Yu; Xingwang Bai; Xueqi Yu; Haiou Zhang Purpose A new wire arc additive manufacturing (WAAM) process combined with gravity-driven powder feeding was developed to fabricate components of tungsten carbide (WC)-reinforced iron matrix composites. The purpose of this study was to investigate...

...Jun Wu; Cheng Huang; Zili Li; Runsheng Li; Guilan Wang; Haiou Zhang Purpose Wire and arc additive manufacturing (WAAM) is a widely used advanced manufacturing technology. If the surface defects occurred during welding process cannot be detected and repaired in time, it will form the internal...

...Ruizhe Wang; Runsheng Li; Guilan Wang; Mingbo Zhang; Jianwu Huang; Hang Lin; Haiou Zhang Purpose Wire and arc additive manufacturing (WAAM) technology-based cold metal transfer (CMT) to produce large aluminum alloy parts has become more and more popular. In WAAM, wire is the only raw material...

... deposited in multi-beads between layers while actively assisting the subsequent layer's deposition in the wire and arc additive manufacturing (WAAM). Hybrid-deposited and micro-rolling (HDMR) additive manufacturing (AM) technology can smooth the weld bead for improved surface quality. However, the micro...

...Xuewei Fang; Chuanqi Ren; Lijuan Zhang; Changxing Wang; Ke Huang; Bingheng Lu Purpose This paper aims at fabricating large metallic components with high deposition rates, low equipment costs through wire and wire and arc additive manufacturing (WAAM) method, in order to achieve the morphology...

...Runsheng Li; Haiou Zhang; Fusheng Dai; Cheng Huang; Guilan Wang Purpose Large-scale aircraft parts usually with many frame features, which consist of intersections. Profile and tensile properties of junctions in wire and arc additive manufacturing (WAAM) are significantly affected by path...

...Bohao Xu; Xiaodong Tan; Xizhi Gu; Donghong Ding; Yuelin Deng; Zhe Chen; Jing Xu Purpose Once an uneven substrate is aligned, traditional control theories and methods can be used on it, so aligning is of great significance for the development of wire and arc additive manufacturing (WAAM...

...Rong Li; Jun Xiong Purpose This paper aims to study the residual stress of deposited components which is a main issue to impede the widespread application of wire and arc additive manufacturing (WAAM). The interlayer dwell time is believed to have an effect on residual stress distributions in WAAM...

...Xiaolong Wang; Aimin Wang; Kaixiang Wang; Yuebo Li Purpose Traditional gas tungsten arc welding (GTAW) and GTAW-based wire and arc additive manufacturing (WAAM) are notably different. These differences are crucial to the process stability and surface quality in GTAW WAAM. This paper addresses...
