Soldagem de revestimento com arame tubular e monitoramento com acelerômetro

Abstract

The welding coating was applied by the tubular wire process shielding gas in the flat position with a conventional current. The base metal used SAE 1020 and the addition of metal used was stainless stell martensitic 410 (CA6MN). Were made assay by varying the welding parameters such as average current, the distance part contact tip and welding speed. Collected data of current, voltage and acceleration with the aid of an accelerometer, these data were analyzed using MatLab software. In the most current level we obtained the best morphology of the weld bead. Through the current graphics, voltage and acceleration was possible to determine the stability of the electric arc during welding.
