  • Method and apparatus for welding sheet overlaps
    Patent number: 7173209
    Abstract: Where can bodies of sheet metal are welded between the welding rollers of a welding machine, the welding current is not applied to the welding rollers until the body is between the welding electrode rollers. In this way, the quality of the weld at the initial weld point is improved, and where intermediate wire electrodes are used, wire breaks are reliably prevented.
    Type: Grant
    Filed: April 26, 2004
    Date of Patent: February 6, 2007
    Assignee: Elpatronic AG
    Inventors: Eugen Müller, Jean-Paul Ruscher
