Abstract

resumo “fontes de alimentação para soldadura com circuito de ponte que fornecem impedância alta/baixa para controlar processos de soldadura de arco de ca” trata-se de sistemas e métodos para fornecer processos de soldadura de arco de ca controlados. em modalidades de fonte de alimentação para soldadura de arco, configurações de circuitos de ponte principal e auxiliar (160, 170) permitem a comutação direcional da corrente de saída de soldadura através do trajeto de circuito de saída de soldadura e fornecem seletivamente um ou mais trajetos de impedância alta para que a corrente de arco decaia rapidamente. o trajeto de impedância alta auxilia na transferência de baixo respingo de esferas de metal derretido de um eletrodo consumível (e) para uma peça de trabalho (w) e auxilia adicionalmente na manutenção ou no reestabelecimento de um arco entre o eletrodo consumível (e) e a peça de trabalho (w) quando uma esfera de metal derretido é transferida.
