Evaluación de la calidad de procesos de soldadura a travès de realidad aumentada

Abstract

Industry 4.0 in the country has a great growth so one of the main problems is the continuous improvement of quality control processes generally in welding, traditional methods of visual inspection are used, and currently the knowledge of new technologies for these methods is booming. A mobile application was developed on Android 10 through a free software such as Unity and Vuforia with Visual Studio 2019, in which the physical parameters were determined to digital parameters for the evaluation of the quality of welding processes through to augmented reality, is so the use of this new application can be displayed on all Android devices in the world. The development of this mobile application using augmented reality is an innovative tool that helps to evaluate the quality of weld seams made in single V butt joints, also by using the user menu you can scan a marker or QR code which must be placed in each joint to be analyzed, in this case the screen displays a menu of options that allows manual selection of the marker scanning options, After selecting the scan, the camera automatically searches for the weld bead, once focused approximately 300 mm long perpendicular to the surface, the screen displays vertical and longitudinal strips, colored strips in which weld width, weld length, undercuts, porosity, and lack of fusion are identified. This application is of great help and continuous improvement in quality control processes used in welding, its use is very simple and the inspection time is much less compared to traditional methods of visual inspection, and in the future you can link these data in real time for interpretation.
