Abstract Scope |
This study investigated the impact of using 1, 2, 3, and 4 wires on the deposition rate, microstructure evolution and mechanical properties of mild steel components produced via Wire Arc Additive Manufacturing (WAAM). To achieve this, we developed an in-house multi-wire Tungsten Inert Gas (TIG) WAAM setup with four wire exit nozzles arranged at 90-degree angles and an oscillatory motion mechanism to ensure uniform material deposition regardless of the TIG gun direction.
Microstructural analysis via SEM revealed grain refinement and phase changes. Mechanical properties, assessed through tensile testing and hardness measurements. Our findings indicate that increasing the number of wires leads to higher deposition rate, grain refinement and notable improvement in mechanical properties. These setups achieved better deposition rate, heat distribution, leading to finer microstructures and fewer defects. This study underscores the potential of multi-wire WAAM for mild steel components and applicable to other materials as well. |
