چکیده مقاله
Wire arc additive manufacturing WAAM is a prominent technique for producing large metallic components due to its high deposition rate Utilizing austenitic stainless steels in this process not only reduces production costs but also provides greater design freedom Among these steels, SS310, known as heat resistant steel in the industry, offers excellent oxidation resistance and high temperature performance However, it is highly susceptible to hot cracking during welding and additive manufacturing processes In this study, the microstructure and mechanical properties of SS310 fabricated using WAAM with Cold Metal Transfer CMT and Gas Metal Arc Welding GMAW processes were compared The results revealed that the CMT process, due to its lower heat input, effectively reduces the susceptibility of SS310 to hot cracking compared to the GMAW process These findings emphasize the importance of selecting an appropriate process to achieve high quality components and minimize structural defects
