Diseño y desarrollo de un sistema semiautomatico de 3 ejes para la inspeccion de juntas soldadas a tope mediante ultrasonido a traves del equipo MFD 800B utilizado en el laboratorio de materiales de la Facultad de Ingenieria Civil y Mecanica

Abstract

This project aims to realize a semiautomatic system which allows to control the movement of the MFD 800B with computer generated commands through the arduino control software in order to facilitate the use to the user, and provide greater firmness and precision in the measurements. In said system the plates to be counted must be positioned, for which calculations were made of the maximum effort that the same can support. In the programming you will find two options which were taken based on the aforementioned equipment. First we have the option for straight transducers which have a functionality to generate waves along their own axis. For the second option there are transverse transducers which generate waves at angles established by each sensor. To obtain the materials, it was decided to carry out a weighting of criteria, with which different alternatives were obtained for each part of the system; A selection was made for the materials of the base, these were decided for being transmission steel to be able to support the loads of the plates and for the joints ABS plastic was used. For parts such as the roof it was decided to use MDF because it does not support loads and have a much lower cost than commonly used covers. Then tests were performed to check the operation of the machine and it was decided to create a user manual in order to avoid inconveniences in the use of the equipment.
