RESUMO

Along the elevators’ history its door has passed through many development phases since its no using of the doors by the ones which could cause injuries to the user. Nowadays the models of the doors panels are safe, however they still have used traditional productive processes (welding) to make the mechanical union among the components. The objective of this work is to develop a metallic panel applying the agglutinated and riveting processes in concomitance in the union of their components and also to demonstrate the viability as an alternative of the welded panel, so that two panels were manufactured and their components had the same dimensions and geometries, differing only on the productive process. One of them their components were jointed by welding MIG and the other one was applied VHB adhesive tape and stainless steel rivets for joining of their components. The legitimation of the alternative among processes was made by using the comparative analysis of the results obtained from two different tests executed on the panels. One of them consists to apply 300N perpendicular to the panel front face, in the more vulnerable point. It is the flexure test. The other test was to submit the panels to torsion efforts, by using the load application of 500N for five minutes. The results of the tests demonstrated that the welded panel has the best rigidity and the agglutinated and riveted panel had the best performance in terms of the used tests.
