Abstract: There is provided a system and method for controlling an ambient magnetic field present in a weld region. At least one permanent magnet is provided adjacent the weld region and is adapted for movement with a welding apparatus along a welding path. The at least one permanent magnet is configured to generate a nulling magnetic field that opposes the ambient magnetic field.

Abstract: There is provided a system and method for magnetic field shielding in a weld region. A shielding device is positioned adjacent the weld region. The shielding device comprises an elliptic body having formed therein an aperture adapted to receive the welding apparatus. The shielding device is adapted for movement along the welding path and configured to generate a nulling magnetic field that opposes an ambient magnetic field present in the weld region.
