Abstract

"MáQUINA DE SOLDAR POR ARCO ELéTRICO E MéTODO PARA CONTROLAR O PROCESSO DE SOLDAGEM DA MáQUINA DE SOLDAR". A presente invenção refere-se a uma máquina de soldar por arco elétrico (10) que realiza um dado processo de soldagem com forma de onda de corrente selecionada realizado entre um eletrodo (24) e o objeto a soldar (26). A máquina de soldar (10) inclui um controlador com um processador digital (30), sensor (44) para leitura instantânea de corrente de soldagem e circuito (56) para converter a corrente instantânea em uma representação digital do nível de corrente de solda instantânea. O processador digital (30) tem circuito de programa (64, 66) para, periodicamente, ler e elevar ao quadrado a representação digital em uma dada taxa, registrador (70, 72) para somar um número N de representações digitais ao quadrado para dar um valor somado e um algoritmo (82, 84, 86, 88) para dividir, periodicamente, o valor somado pelo número N a fim de proporcionar um quociente e, então, tomar a raiz quadrada do referido quociente para, assim, construir, digitalmente, sinal rms (40) representando a raiz quadrada média da corrente de solda.
