ALTERAÇÃO NO PROCESSO DE SOLDAGEM DE ARCO SUBMERSO PARA SOLDAGEM MIG/MAG EM BUSCA DA REDUÇÃO DE CUSTOS NA PRODUÇÃO DE RESERVÁTORIO DE AR PARA SISTEMA DE FREIOS DE VEICULOS PESADOS

Abstract

This work addresses a study on the change in the Submerged Arc welding process to the MIG / MAG welding process in the manufacture of air reservoirs for the brake system of trucks, buses and agricultural machinery in the company in the metallurgical industry. In order to be more competitive in the market, the company seeks to reduce costs and optimize operations for the delivery of the final product, such an approach involves a modification in one of the production lines of air reservoir in circular weld, which was produced by submerged arc welding in which it uses the flow of granulated mineral, passing to the MIG / MAG process that is carried out by mixing the gases carbon dioxide (CO2) and argon (Ar). The change took into account the relationship between the flux and the solder gas used, the comparison was the starting point for the change to take place, a preview was made according to the diameter of each tank. With the change it was possible to observe a 60% annual cost reduction in the welding process, in addition to a reduction in labor.
