Desarrollo de un plan de mantenimiento preventivo para los equipos de soldadura en los procesos SMAW, GMAW, GTAW Y PAW en la empresa carrocerías Yuaysa

Abstract

The importance of this technical project lies in the development of a preventive maintenance plan for the welding equipment of the company Carrocerías YUAYSA. In this company in the production area there are four different types of welding equipment: SMAW, GMAW, GTAW and PAW, in which a high priority analysis was carried out in terms of control and maintenance. As a first point, basic information was collected from the aforementioned machines, emphasizing their technical characteristics, main components and working hours. To complement this information, an FMEA and criticality matrix was established for each piece of equipment, thus obtaining the most critical components and the pre-established activities to perform maintenance. Times were analyzed such as: mean time between failures, mean repair time, downtime, operating time, among others, thus establishing machine availability for maintenance through the calculation of a constant failure rate. Finally, maintenance ranges were developed with preventive activities previously analyzed, activities which detail the frequency in which they will be executed each month of this year, likewise with all this analysis, an editable program was lost in a free preventive maintenance software in the machines studied, with a maximum of three activities per month, which was delivered to the company where the operators or personnel in charge of these teams will have total availability to use and develop the maintenance plan.
