Melhoria de processos como solução de problemas ocasionados por aspectos ambientais no processo de soldagem

Abstract

This study aims to analyze why an unacceptable number of discontinuities were detected in the structural components od products manufactured in a company located in the South Fluminense region, manufacturer of heavy machinery for use in mining and civil construction, due to the growing demand for tis products there was a unplanned increase in its production, exceeding the result. Due to the structural failure resulting from the growth in production, onde of the factors affected is the storage location of the raw material, whichis in an inappropriate location. The plates used in manufacturing are stored in the external patio, between the welding shed and the plating, being directly exposed to climatic actions such as rain and sun. Such exposure harms the welding process, since the humidity caused by rain accelerates the oxidation process. Another prolem arising from the orginal model, causing the newly welded parts to be exposed to the actions of cold air caused by the wind, interfering with the cooling process of the welded structure of the material, and when this is not well controlled, it can result in the results of this study, it was necessry to collect data regarding the discontinuities detected in the comany's products; analyze the structure for storing raw materials and athe plant where the results. From the analysis of the data obtained, it was possible to identify the importande of having a suitabe place for the storage of the ra possible to dentify the importance of having a suitable place for the storage of the raw material to be used in the process, in order to reduce the apperance of discontinuities arising fron the contamination of the materials used, it was also possible to observe the importance of an adequate structure for sealing the welding stations in order minimize the importance of wind action o the newly welded structures that are in the cooling process.
