Abstract

(en) method for starting a submerged arc welding process and welding apparatus abstract: (en)a method comprising an arc ignition phase (ip), an arc-stabilizing phase (ap) and a stable arc phase (sp). the arc stabilizing phase comprises an initial sub-phase (is) comprising the step of feeding at least one hot wire (4, 12) at constant feed speed and a main sub-phase (ms) comprising the steps of feeding said hot wire at constant feed speed and feeding at least one cold wire (22) at constant feed speed. the stable arc phase comprises the steps of continuously adjusting the feed speed of the hot wire and continuously adjusting the feed speed of the cold wire. the invention also relates to a welding apparatus (1) for carrying out the method. the welding apparatus comprises a hot wire feeding means (150), a contact means (2), a cold wire feeding means (35) and a control unit (31). the control unit is adapted to control said hot wire feeding means to feed the hot wire at a constant feed speed during the initial sub-phase, feed the hot wire at a constant feed speed during the main sub-phase and to continuously during the stable arc phase adjust the feed speed of the hot wire. the control unit is adapted to control said cold wire feeding means to feed the cold wire at a constant feed speed during the main sub-phase and continuously during the stable arc phase adjust the cold wire feed speed. tradução do resumo 1 resumo método compreendendo uma fase de ignição de arco (ip) e uma fase de arc o estável (sp). a fare de estabilização de arco compreende uma subfase inicial (is), compreendendo a etapa de alimentar pelo menos um arame quente (4, 12) a uma velocidade de alimentação constante e uma subfase principal (ms) compreendendo as etapas de alimentar o dito arame quente a uma velocidade de alimentação constante (ms) e alimentar pelo menos um arame frio (22) a uma velocidade de alimentação constante. a fase de arco estável compreende as etapas de continuamente ajustar a velocidade de alimentação do arame quente e continuamente ajustar a velocidade de alimentação do arame frio. a invenção também se refere a um aparelho de soldagem (1) para realizar o método. o aparelho de soldagem compreende um meio de alimentar arame quente (150), um meio de contato (2), um meio de alimentar arame frio (35) e uma unidade de controle (31). a unidade de controle é adaptada para controlas o dito meio de alimentação de arame quente para alimentar o arame quente a uma velocidade de alimentação constante durante a subfase principal e continuamente durante a fase de arco estável ajustar a velocidade de alimentação do arame quente. a unidade de controle é adaptada para controlar o dito meio de alimentação de arame frio para alimentar o arame frio a uma velocidade de alimentação constante durante a subfase principal e continuamente durante a fase de arco estável ajustar a velocidade de alimentação de arame frio.
