Abstract
The automation in the welding processes brings great advantages, as the control of the variables and quality of the weld bead. In the study on weldability, such as the behavior of the electric arc, physical and metallurgical aspects of the weld bead it is necessary to present regularity such as welding speed, arc height, depth, and angle of attack. The variables involved in manual welding processes or semi-machined, have a high level of operator dependence, making the reproducibility hard or even making it unproductive to perform a weld with good quality. The study of these variables have a fundamental importance for improving the control of the welding processes, obtaining weld beads without defects, reducing the amount of spatter, predicting the penetration of the pass, evaluating the amount of heat transferred to the base metal and controlling the distortion of the welded structure. The aim of the present work is to realize the mechanical design of a device to automate the welding processes by coated electrodes, gas metal arc, tubular wire and gas tungsten arc, in order to obtain improvements to perform experimental studies, which will allow a better analysis of metallic transfer, weldability, melting rate, influence of parameters and welding variables, with a high degree of repeatability and precision. The construction of the mechanism enabled the mechanical design confirming its ability to act.
