Automatización de la soldadura de tubos mediante el proceso MIG/MAG.

Abstract

The MIG/MAG machine to make welding strings has been used in this project and the different standards already established by the LINCOLN ARC WELDING FOUNDATION have seriously been considered as well. These aims were fulfilled thanks to the creation of a prototype designed to weld and fill different kinds of tubes roundly, independently from having pipes made of steal or iron from low alloy. An electronic system that has a serial communication pattern with the computer, by means of a software that was adapted to the specifications and objectives stated in this project, was implemented to be able to weld the tubes. Additionally, an electronic circuit which is handled by the microcontroller (PIC 16F872) allows to activate the motor steps used to control the prototype. A higher precision level while working on the welding process has been reached through these kind of motors. In this project, it’s been possible to automatize the welding process thanks to a computerized control and high- quality welding strings have been gotten in shorter time than the one usually taken in many industries and at a considerably lower price because the imperfections that welding normally has when it’s done manually have been eliminated. A prototype that makes it possible to weld roundly and to fill in through the MIG/MAG process was built and it is greatly useful in the filling of steal axis which have a low carbon content and depending on the electrode wire that would be used as a supply.
