Energy Consumption of Welding-Based Additively Manufactured Materials

The objective of this study is to determine a detailed energy model for Gas Metal Arc Welding (GMAW), Manual Metal Arc Welding (MMAW) processes and comparing energy consumptions of both techniques for additively manufactured rectangular blocks. Energy consumption as function of time and power calculated for Mild steel- MS-ER70, MS-E6013, stainless steel SS-ER347, SS-E308L-16, AlSi-3 ER4043 rectangular solids manufactured by welding-based additive manufacturing. Qualitatively it is known that GMAW takes less energy comparing MMAW process. However, tools and dataset to quantitatively determine energy consumption of each step of GMAW, MMAW additively manufactured materials has been missing. Energy consumption is divided for pre-processing, WAAM process, post-processing. Even each of this process demanded energy input also traced. Comparisons of both energy values with carbon foot print and considerable parameters are discussed in detail.
