First Claim
Patent Images
1. A welding arc manipulation unit, comprising:
- a support structure which supports a magnetic coil which generates a magnetic field in response to an electrical current;
a magnetic probe magnetically coupled to said magnetic coil and extending below said support structure such that said magnetic probe can extend into a welding gap to deliver a magnetic field to a welding arc; and
a shielding gas tube coupled to and extending below said support structure such that said shielding gas tube can extend into said welding gap to deliver shielding gas to said welding arc.

Abstract
A welding system is provided which can weld in narrow gap thick walled work pieces, the welding system having a magnetic field unit which contains a magnetic coil, a magnetic field probe, and a shielding gas tube and nozzle. The unit having a shape and configuration which delivers the shielding gas and magnetic field close to the welding arc so as to provide for a shielded welding arc which is manipulated as desired by the magnetic field.

12. A welding system, comprising:
-
a welding power supply coupled to a welding head which generates a welding arc between an electrode and a workpiece; a magnetic field control device; and a welding arc manipulation unit, said unit comprising; a support structure which supports a magnetic coil which generates a magnetic field in response to an electrical current from said magnetic field control device; a magnetic probe magnetically coupled to said magnetic coil and extending below said support structure such that said magnetic probe can extend into a welding gap to deliver at least a portion of said magnetic field to said welding arc; and a shielding gas tube extending below said support structure such that said shielding gas tube can extend into said welding gap to deliver shielding gas to said welding arc. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
