Garantia da qualidade da construção soldada de caldeiras industriais

Abstract

A garantia da qualidade é um requisito imprescindível e incontornável na fabricação metalomecânica. A obrigatoriedade de cumprimento deste requisito por parte dos fabricantes, depende do enquadramento e âmbito aplicável ao produto. Desta forma, o fabricante deve não só conhecer e respeitar a legislação e regulamentação vigente, como também dominar a extensa normalização aplicável aos produtos que fabrica. Em particular, fabricantes cujo produto seja baseado em construção soldada e sujeito à marcação CE, têm por obrigação conhecer e implementar todas as disposições necessárias à conformidade do produto, desde a sua conceção até à sua disponibilização no mercado. Nesse sentido, o objetivo deste trabalho é descrever, especificar e resolver as diversas etapas que permitem a um fabricante de caldeiras de vapor garantir a qualidade na construção soldada do seu produto, com tudo o que isso implique. Entendese que, atualmente, a problemática do fabricante não é tanto a quantidade e amplitude dos meios físicos de fabricação, mas sim o domínio da técnica e atualidade de conhecimento específico ao serviço da conformidade de produto. É proposta uma metodologia de abordagem à construção, assumindo o papel do fabricante, desde o enquadramento do próprio produto, até à inspeção e ensaios finais. Pretende-se detalhar e documentar tecnicamente, de forma completa cada uma das etapas, em conformidade com a legislação e códigos de construção aplicáveis à caldeira em estudo.

Quality assurance is an essential and indispensable requirement in metalworking. The obligation of manufacturers to comply with this requirement depends on the framework and scope applicable to the product. Thus, the manufacturer must not only know and respect the current legislation and regulations, but also the extensive standardization applicable to the products. Specially, manufacturers whose product is based on welded construction and subject to CE marking, have the obligation to know and implement all the necessary provisions for the conformity of the product from its conception to the availability of the product on the market. In this case, the objective of this work is to describe, specify and solve the various steps that allow a manufacturer of steam boilers to guarantee the quality in the welded construction of their products, with all that this implies. Actually, the manufacturer's problem is not so much the quantity and capacity of the physical resources of manufacture, but rather the mastery of the technique and actuality of specific knowledge required in order to ensure the product compliance. A methodology to approach construction is proposed, assuming the manufacturer role, from the framing of the product, to inspection and final testing. It is intended to detail and technically fully document each step, in accordance with the legislation and building codes applicable to the boiler under study.
