Análise de viabilidade do aumento da velocidade de soldagem para a obtenção de aumento quantitativo na produção de racks metálicos

Abstract

Industrial metal racks are used for the purpose of storing, moving, transporting products and supporting large loads, as well as in organizing the production line, as they offer practical storage with spatial compaction, due to the fact that there is the possibility of vertical storage, allowing for a larger area available in the work field. Welded joints have a crucial function in this industrial sector, due to the fact that the manufacture of these metal racks depends, on a large scale, on the welding process, largely because it is a fast, economical and safe process, compared to other manufacturing processes. The present work aims to study the feasibility of increasing welding speed to obtain productive gains in relation to the quantity of racks produced, without substantial losses in accordance with the application of the Eurocontainers Brasil methodology, regarding stress and deformation analyses. of the material studied for the needs presented. The present work proposes a comparative analysis in relation to the thermal input contained in a welding process of a welded joint, through analyzes of characterizations of the mechanical properties, via tensile and bending tests of the joints studied. It was concluded that welding at normal speed is adequate according to the standard parameters and should continue to be used, however, the improvement suggested through this increase in speed, even though it presents a satisfactory result in relation to design and manufacturing methodologies, still requires standardization of welding procedures to fully meet the requirements of the ASTM A36 standard
