Elaboración de un plan de mantenimiento mediante el análisis de los modos de falla para los equipos en la planta de soldadura de la Empresa CIAUTO Cía. Ltda.

Abstract

The objective of this curricular integration work consisted in the elaboration of the maintenance plan through the analysis of the failure modes for the equipment of the welding plant in CIAUTO CÍA LTDA company. It began with the evaluation of maintenance management using the "Maintenance Effectiveness Survey", which allowed to know the level of maintenance management. The technical inventory of the assets was verified and updated according to the guidelines of ISO14224 Standard. In addition, the criticality analysis was carried out, relying on the semi-quantitative method of total criticality by risk (CTR), identifying critical systems. Subsequently, the RCM methodology was applied, which is based on the analysis of modes and effects of failures to high criticality systems. The information obtained was entered and configured into SisMAC maintenance software. Finally, maintenance personnel were trained on the maintenance plan and systematization. All this was done to determine the maintenance plan that consists of maintenance activities, frequencies and the required specialists; 299 maintenance tasks for critical systems and 1.207 system tasks medium and low criticality. For each maintenance task was assigned the necessary such as: materials, spare parts, tools and labor. It is concluded that the elaboration of the maintenance plan will improve the operational reliability of equipment achieving to maintain the quality standards of the product at all times and customer satisfaction. Therefore, it is recommended to update the technical inventory when new machinery is purchased or decommissioned and regular review the maintenance plan obtained through the analysis of failure modes.
