Projeto e construção de uma estrutura automatizada para soldagem

Abstract

A mechanical structure may be able to make a weld bead in an automated way by controlling some of the process parameters and improving weld bead stability and quality. It can be used in the research area to analyze the weld, since the precise control of the process variables ensures that the physical, chemical and metallurgical properties of the welded joint have uniformity throughout. The control of opening / closing of the arc, torch / piece distance and linear torch movement will be controlled through an embedded electronic system with Stepper Motors connected to the axes and a controller board that receives the command from the operator and transmits to the actuator (can mention the Arduino, which is free hardware that is easily accessible). In this work, the design, dimensioning and construction of the mechanical structure was carried out, which will have a MIG / MAG torch attached to perform the welding, materials of easy access and low cost will be used in the construction of the structure. The methodology of the project consists of a bibliographic review on machine, welding, components and parts projects, collecting information of great importance for the elaboration of this project. After construction, the structure was subjected to tests to evaluate its functioning. The final result was satisfactory, the structure presented excellent functionality and perfect integration of the mechanical part with the electronics.
