- Robust regression analysis for the relationship between welding parameters and microhardness of 410 NiMo martensitic steel deposits on SAE 1020 steel João Roberto Sartori Moreno Celso Alves Corrêa Elisangela Aparecida da Silva Lizzi Émillyn Ferreira Trevisani Olivio Paulo Sergio Olivio Filho Ana Carla Santos da Silva Tiago Felipe de Abreu Santos Ingeniería FCAW Claddings EC410NiMo fusion zone statistical models The objective of this study was to analyze the flux-cored arc welding (FCAW) welding parameters and microhardness levels on surface quality of 410 NiMo martensitic stainless-steel coatings. The parameters of the FCAW process applied to the coating, included pulsation frequency, voltage, welding speed, average current and contact tip to work distance. The welding was carried out by the pulsed tubular wire process with pulsed current, constant voltage, Ar+2% O2 shielding gas and short-circuit metal transfer for the deposition of EC410 NiMo Martensitic Steel Deposits alloy coatings on a SAE 1020 steel substrate. For the statistical analysis, the Taguchi experimental planning was applied to test the influence of the parameters of the FCAW process (average current, CTWD, pulsation current and welding speed) on the coating properties. The best configuration with respect to the increased microhardness of the fusion zone in the coating welding process is: Average Current 200 A; CTWD 40 mm; Pulsation Frequency 26.31 Hz and Welding Speed 300 mm min.-1. The lowest microhardness of the melting zone in the coating welding process is: Average Current 170 A; CTWD 30 mm; Pulsation Frequency 23.26 Hz and Welding Speed 400 mm min.-1. 2021 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303271763009 https://www.redalyc.org/journal/3032/303271763009/ https://www.redalyc.org/journal/3032/303271763009/html/ https://www.redalyc.org/journal/3032/303271763009/303271763009.epub https://www.redalyc.org/journal/3032/303271763009/movil https://doi.org/10.4025/actascitechnol.v43i1.49807 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
