Description

This study evaluates the influence of welding parameters on the chemical composition of weld overlays of the AWS E 308-L T1 applied by the FCAW and SAW process, as well as their influence on the microstructure and microhardness of the weld overlays. The characterization of chemical composition was performed by EDX (Energy Dispersive X-ray Analysis), the microstructure was investigated by optical microscopy and Vickers microhardness. The contents of Cr, Ni, Mn, Mo, Nb and Si varied as a function of welding parameters, the microstructure and microhardness varied as a function of heat input and chemical composition. The resulting microstructure showed an austenitic matrix with lacy ferrite and ferrite FA, with an average hardness of 191.6 HV for the FCAW process and 210 HV for the SAW process. (author)
