ANÁLISE DE MÉTODOS E PROCESSOS DE SOLDA PARA MELHORAR O CONTROLE DE DEFORMAÇÃO

Abstract

The theme of this work was “analysis of welding methods and processes to improve deformation control”. The general objective of the work was to analyze the cost-benefit of the different welding methods and processes in low carbon steel meeting the objective of deformation control. Through bibliographic research, the welding methods and processes, the control of product distortion generated by the weld and the MIG / MAG weld were identified. A case study was presented in order to identify the control of the deformation of a product in the thermally affected zone in the weld joining of low carbon steel components, evaluating different methods and processes. It was intended to reach a conclusion of which solution will promote better quality and control. Finally, the cost-benefit of each method and process was analyzed, taking into account, in addition to the factors mentioned, the payback time in a production line of compressed air tanks with application in trucks and all heavy automotive lines. It was identified that MIG / MAG welding guarantees the best welding method and process, presenting the best performance and cost-benefit, guaranteeing the quality and mechanical properties of the components welded in the product. It is concluded that the methods, welding processes and the study of the welding sequence, is of its importance for reducing and eliminating distortions caused by the product process. This is due to the need to improve productivity and quality while reducing costs.
