Numerical prediction of microstructure and hardness for low carbon steel wire Arc additive manufacturing components Ghent University
The objective of this research is to define an optimized strategy for wire arc additive manufacturing (WAAM) process with a numerical tool. In this paper, a three-dimensional scaled steel plate model (120 mm x 24 mm x 6 mm) is built for numerical simulations to replace the expensive physical WAAM experiments. A series of thermo-metallo-mechanical analyses is conducted by using ABAQUS CAE user subroutines in which, thermal, metallurgical and ...
A benchmark of mechanical properties and operational parameters of different steel filler metals for wire arc additive manufacturing Ghent University
Additive manufacturing processes play a disruptive role in several industrial sectors. Among them, wire arc additive manufacturing (WAAM) is a very promising process for the production of large-scale steel components and structures. As a common characteristic of innovative technologies, this process requires additional research and experimental work in order to understand how its thermal cycles will modify the mechanical and metallurgical ...
Development of low-cost production process for prototype components based on Wire and Arc Additive Manufacturing (WAAM) KU Leuven
Wire and Arc Additive Manufacturing is a fast-growing technology that allows to produce medium to large metal parts in both a material- and cost-efficient way. Because it is based on existing welding technology, it is certainly an affordable technology for small and medium sized companies. However, the integration of this technology for prototype manufacturing still needs certain difficulties to be solved, such as the determination of process ...
Design Strategies for Bi-Metallic Additive Manufacturing in the Context of Wire and Arc Directed Energy Deposition KU Leuven
While the recent research in manufacturing bi-metallic structures using wire and arc directed energy deposition focuses on feasibility studies to understand material compatibility, the study presented here encircles a larger design framework, integrating deposition process, intermediate surface conditions, and mutual deposition (hatching) direction. The investigation addresses the issues associated with manufacturing actual bi-metallic ...
