Abstract Scope |
This study explores the use of Robotic Wire Arc Additive Manufacturing (WAAM) to fabricate large-scale 316L stainless steel structures for potential forging preforms. A full wall sample was successfully printed using a robotic WAAM setup equipped with a pulsed Gas Metal Arc Welding (GMAW) process. To investigate the thermomechanical properties of the printed material, compression tests were conducted at a preheat temperature of 1600 °F (871 °C) and a strain rate of 0.01 (in/in)s⁻¹. A custom-designed nickel-based alloy platen was fabricated to perform the high-temperature tests. The data were recorded during testing and flow stress were calculated for the samples. The results demonstrate that WAAM can produce 316L stainless steel components with favorable mechanical behavior under forging-like conditions, suggesting its potential as a cost-effective alternative for manufacturing preforms in forging industries. |
