  • Patent number: 11389889
    Abstract: The present application relates to an arc welding arrangement and an electric arc welding method to be used with the arc welding arrangement. The arc welding arrangement comprising a first power source, a first electrode connected to say first power source, and a second electrode, said first electrode being adapted to generate a weld pool via a first electric arc present within a first arc region. The second electrode is operated at welding parameters adapted to ensure that excess energy from at least said first electrode is required to maintain said second arc ignited. The method comprises the step of feeding said second electrode so that it is allowed to consume excess energy from said first electrode to maintain said second arc ignited.
    Type: Grant
    Filed: November 25, 2019
    Date of Patent: July 19, 2022
    Assignee: ESAB AB

  • Patent number: 10486256
    Abstract: The present application relates to an electric arc welding method to be used with an arc welding arrangement (1) comprising a first power source, a first electrode (2) connected to said first power source, and a second electrode (7), said first electrode (2) being adapted to generate a weld pool (28) via a first electric arc present within a first arc region (31) and said second electrode (7) being adapted to generate said weld pool via a second electric arc present within a second arc region. The first electrode (2) is operated at welding parameters adapted to maintain said first arc ignited. The second electrode (7) is operated at welding parameters adapted to ensure that excess energy from at least said first electrode (2) is required to maintain said second arc ignited. The method comprises the step of feeding said second electrode (7) so that it is allowed to consume excess energy from said first electrode (2) to maintain said second arc ignited.
