  • Welding apparatus for sleeves
    Patent number: 6630642
    Abstract: For arc welding a sleeve 3 to a workpiece surface 2, a sleeve holder 1 is surrounded by a field-former unit which contains a magnet coil 4, a magnetic flux return member 6 and a field former 7. A magnetic field is generated with a field component extending radially to the sleeve 3 within the welding gap to set the arc in rotation. To ensure a constant magnetic flux, the field-former unit, in particular its magnet coil 4, is cooled by a temperature-controlled cooling medium circulated through the welding head.
    Type: Grant
