Abstract

Additive manufacturing (AM)/3D printing is a new manufacturing process that expands the creative possibilities available to product designers. These last several years have seen a rise in the popularity of materials based on metal. An end result is achieved by serially applying thin layers of material. Thus, the entire process of creating new products is greatly accelerated. However, the technology is still immature and cannot fully replace existing methods due to its subpar mechanical properties. Furthermore, the cost of using a laser to create commercial 3D metal prints is very high. MIG, or metal inert gas, is a viable replacement that saves money and resources (MIG). Additive manufacturing with MIG welders involves the use of high-temperature materials and processes, hence this study will examine the interplay between materials and heat (MIG-WAAM). When printing in metal, each layer must go through a process of heating, cooling, hardening, and reheating. In other words, we need to know how the layers interact with one another and the environment before we can construct a 3D object using a melt pool and a single-track mechanism and mixxing with Alumina Oxide and Titanium Carbide Powder. Many temperature-measuring instruments, such as pyrometers and thermal cameras, as well as high-speed cameras, will be used to keep an eye on the process as it unfolds. Dimensional accuracy, microstructure, the heat affected zone (HAZ), hardness, and porosity are just few of the physical phenomena that are intended to be studied in relation to processes. The Response Surface Methodology will be used to establish a connection between the imaging system's recorded physical events and the pyrometer's readings (RSM). Geomagic software and coordinate measuring equipment will be used to compare the CAD and printed structures, taking into account all relevant parameters and melt pool behaviour (CMM). The future of porosity calculations lies on Archimedes' Principles. Last but not least, we'll be doing static strength tests in accordance with ASTM E8M-04. This will aid in the study of the correlation between the qualities of the 3D structure process and the properties of the wire arc robotic system while making metal additively. i)The surface quality of the wall and the accumulation efficiency both increased despite the fact that the wire feeding speed remained unchanged and the amount of heat input and alumina oxide and titanium carbide paste remained unchanged. The microstructure is similar to that of stainless steel, but the combined strength of alumina carbide and titanium oxide makes the material far more formidable than stainless steel alone.
