초록

Additive manufacturing of novel metals has received much attention as an alternative to traditional manufacturing because of its high material efficiency, shorter lead time and higher design flexibility. However for most additive manufacturing base substrate were not considered in the calculations. Generally, the base substrate is applied in the same material or similar chemical component alloys. This is in addition to the feedstock and the cost of use since it is discarded after the process in the process of removing the base substrate after the process. Therefore, it is very important to minimize the cost of the base substrate and the use of cheaper and different materials should be considered. In this study, substitution of base substrate in the production of arc and wire additives using gas metal arc welding (GMAW) was evaluated. Inconel 718 was deposited on two different substrates (SS275, Inconel 718). In SS275 substrate, we observed that after three layers of deposition, the deposition width is similar to the thickness of the Inconel 718 substrates. It has also been found that dilution from the fourth deposition layer with respect to the SS275 substrate by examining the dilution from the viewpoint of the deposition layer can be solved by cutting the first three layers of the dilution problem.
