Abstract

Patente de Invenção: <B>"SOLDADOR COM ELETRODOS EM SéRIE E MéTODO PARA SOLDAGEM COM DOIS ELETRODOS"<D>. Um equipamento de soldagem a arco elétrico compreendendo pelo menos um primeiro eletrodo consumível e um segundo eletrodo consumível que se movem em harmonia ao longo de uma trilha de soldagem entre as bordas de duas chapas adjacentes, mutuamente aterradas, uma primeira fonte de força para passar uma primeira corrente de soldagem a uma primeira baixa freq³ência entre o primeiro eletrodo e as duas chapas, uma segunda fonte de força para passar uma segunda corrente de soldagem a uma segunda baixa freq³ência entre o segundo eletrodo e as duas chapas, onde cada uma das fontes de força inclui uma entrada de voltagem trifásica operada à freq³ência da linha, um retificador para converter a voltagem de entrada para uma cadeia de voltagem CC e um inversor do tipo comutador de alta freq³ência convertendo a cadeia de voltagem CC para uma corrente CA de alta freq³ência, um circuito retificador de saída para fornecer um terminal de voltagem positiva e um terminal de voltagem negativa, e uma rede de comutação de saída operada a uma dada baixa freq³ência para dirigir uma corrente pulsante de soldagem à dada baixa freq³ência dos dois terminais através de um dos eletrodos e das chapas, e um circuito para ajustar independentemente a baixa freq³ência dada de forma que o valor da primeira baixa freq³ência da primeira fonte de força é diferente da segunda baixa freq³ência da segunda fonte de força.
