Avaliação da eficiência da manutenção preventiva em máquinas de solda por indução com ênfase nos módulos eletrônicos

Abstract

Preventive maintenance plays a crucial role in modern industries, particularly in highproduction environments and sensitive equipment such as induction welding machines used in metal tube manufacturing. As industrial electronic systems, like welding modules, become increasingly complex, preventive maintenance emerges as a fundamental strategy to ensure operational continuity, reduce operational costs, and improve system reliability. In the context of steel tube production, induction welding generators are responsible for processes that require precision and thermal stability, making them susceptible to failures that can compromise product quality and production efficiency.This study aims to analyze the effectiveness of preventive maintenance in induction welding machines, with a special focus on critical electronic modules. The research seeks to identify the primary failure modes in electronic components, assess performance indicators such as Mean Time Between Failures (MTBF), Mean Time to Repair (MTTR), and operational availability, and compare equipment performance before and after the implementation of preventive actions.Through the collection of historical maintenance data, the study identified recurring failures and their causes, allowing for the application of targeted preventive actions for each identified failure mode. Data analysis showed significant improvements in operational indicators, with increased MTBF, reduced MTTR, and higher equipment availability, resulting in more stable and cost-effective operations. Additionally, the economic evaluation of the impact of preventive actions highlighted the reduction of costs related to emergency repairs and unplanned failures, providing a positive return on investment (ROI). This study emphasizes the importance of preventive maintenance in ensuring the efficiency and reliability of induction welding systems, contributing to continuous improvement in industrial processes and sustaining competitiveness in the sector.
