Estudo sobre a evolução dos processos de união na indústria automobilista

Abstract

Welding is a process that promotes the union of differents parts mainly by localized fusion. The main purpose is the junction / fusion of the parts, by making them to behave as one, without compromising the physical and chemical properties of the welded materials. The history of welding began in 1801, during the industrial revolution, when the electric arc was discovered. In 1877, resistance welding was studied and, in 1885, arc welding was developed using graphite electrode which was later replaced by metal wire. A few decades later, arc welding became the most popular process. In this text, the evolution of the welding processes applied on automotive industry was presented.
