Processo de soldagem MIG do inconel 625 com e sem posterior refusão por TIG

Abstract

In this study, we present the results obtained from welding Inconel 625 alloy using the MIG welding process, with and without TIG re-melting. The primary objective of the study was a detailed analysis of the microstructures formed during the welding process, investigating material diffusion, characteristics of affected heat-affected zones and dilution zones. Additionally, defects arising from the welding procedures were identified and examined. For sample analysis, they were initially sanded with different grits to refine the surface for visualizing the microstructures of the welded material. Data collected from the welding processes employed were duly recorded and analyzed. The results of the analyses are presented in detail, including a discussion on the defects identified in the samples. This work contributes to a deeper understanding of welding processes involving Inconel 625 alloy, providing valuable insights for optimizing and controlling these processes in industrial and technological applications.
