A constante e permanente insatisfaĆ§Ć£o do ser humano, aliada Ć evoluĆ§Ć£o das sociedades nas suas variadas vertentes: social, intelectual, tecnolĆ³gica, econĆ³mica, leva Ć constante procura de melhores soluƧƵes, com o fim comum de se obter ganhos com o menor consumo possĆvel de recursos. Foi este princĆpio que, norteou o desenvolvimento do equipamento de ligaĆ§Ć£o de condutas por soldadura, e consequentemente, forneceu matĆ©ria para suportar esta dissertaĆ§Ć£o. A soldadura de condutas por fusĆ£o era atĆ© entĆ£o uma operaĆ§Ć£o confinada a produtos de dimensƵes considerĆ”veis, tanto na espessura quanto no diĆ¢metro, e a alguns materiais de maior complexidade de conformaĆ§Ć£o, como por exemplo o aƧo inoxidĆ”vel, sendo que as de espessuras mais delicadas, se destinavam normalmente Ć uniĆ£o por conformaĆ§Ć£o mecĆ¢nica (costura obtida por dobragem e esmagamento dos bordos longitudinais) mas, as exigĆŖncias do mercado e a competitividade cada vez maior, deu origem a um novo paradigma que, basicamente direciona esta operaĆ§Ć£o para a soldadura longitudinal das condutas, independentemente das suas dimensƵes e dos materiais que as constituem. A filosofia nĆ£o Ć© recente e atĆ© jĆ” existem no mercado mĆ”quinas capazes de o fazer, mas a sua complexidade, limitaƧƵes no que concerne Ć variedade dimensional e o seu custo, serviram de motivaĆ§Ć£o e ensejo ao desenvolvimento deste projeto. A empresa SERVENTAR, na pessoa do Sr. Filipe Serrado, lanƧou o desafio e demonstrou todo o interesse no acompanhamento e materializaĆ§Ć£o do projeto/protĆ³tipo, tendo como principal objetivo o incremento da produtividade da sua unidade, mas nĆ£o descartando a reproduĆ§Ć£o e comercializaĆ§Ć£o do exemplar.
The constant and permanent dissatisfaction of the human being, in addition with the evolution of societies, in their various aspects: social, intellectual, technological, economic, among others, leads to a constant search for the best solutions, which the common goal is obtaining gains with the least consumption of resources. It was this principle that guided the development of Longitudinal Seam Welding equipment and, consequently, provided material to support this dissertation. Ducts welding was until then an operation confined to products of considerable size, both in thickness and diameter, and in some materials of higher conformation complexity, such as stainless steel, given that those with more delicate thickness were usually devoted to beading (the folding and crushing of the longitudinal edges), but the demands of the market and the increasing competitiveness have given rise to a new paradigm that basically directs this operation to the longitudinal welding of the ducts, regardless of their dimensions and materials that constitute them. The philosophy is not recent and already exists in the machines market that are capable to do it. However, the complexity and their limitations concerning to the variety of the dimensional and its cost, delivers the motivation and the opportunity to develop this project. The company SERVENTAR, in the name of Mr. Filipe Serrado, issued a challenge and reveals all the interest to monitor the pilot project, aiming to increase the productivity of his unit, but not discarding the reproduction and the deliver to the market of this exemplar
