Análisis de desgaste abrasivo de rellenos de soldadura de acero inoxidable por proceso SMAW sobre acero AISI-304 evaluado en un medio acuoso bajo la norma G105-20

Abstract

This study examines the issue of abrasive wear in AISI 304 stainless steel and utilizes welding fillers applied through the SMAW process to significantly reduce its wear rates in aqueous environments. Constant exposure to this type of wear diminishes the durability and performance of stainless-steel components, resulting in costly maintenance and replacements in a variety of industrial applications. The tribological properties inherent to each material were evaluated to determine the filler with the highest wear resistance. Specific stainless-steel electrodes, such as E308L-16, E309-16, E312-16, and E410-16, were employed during the research, following the guidelines set forth by ASTM G105-20. Specimens were immersed in wet abrasive sand under constant load for predetermined times in the experiment. The behavior of AISI 304 stainless steel in aqueous environments was assessed through weight difference measurements and wear rate analysis. The results highlight the effectiveness of some welding fillers, such as the E410-16 electrode, in reducing the abrasive wear of AISI 304 stainless steel. ASTM G105-20 ensured that the collected data were valid, with the coefficient of variation within the allowed limits. Finally, this research has a direct impact on improving the wear resistance of stainlesssteel components in practical applications, opening new possibilities to maximize material durability and reduce maintenance and replacement costs.
