Análise do perfil de solda de junta “T” soldada por arame tubular com gás de proteção e corrente pulsada

Abstract

This work will address sample preparation, analysis and discussion of the results of the soldiers bodies with T Joint with cored wire and pulsed current, were processed outside the Campus Cornelius, but with known origin. We attempted to relate the pre-set welding parameters with the result of the weld beads obtained. Here, the ANOVA was used as statistical analysis for detecting and evaluating the influence of the pulse parameters (peak current, base current, peak time and pulse frequency), welding speed and distance of the weld (Stick- out) on the geometry of the weld bead and the establishment of specific welding conditions such as shielding gas, material and diameter of the tubular wire, the base material characteristics and welding position. We conclude that there is positive relationship between process variables and the dimensional result of weld beads.
