Abstract
A consumable assembly for use in an arc welding apparatus is provided that includes a nozzle assembly having a nozzle body, an insulator disposed within the nozzle body, and a nozzle insert disposed within the insulator. The nozzle insert includes an internal gas diverter. A contact tip is disposed within the nozzle assembly and includes at least one aperture extending from an exterior portion to an internal cavity, an exit orifice, a distal end face, and an exterior surface extending between the at least one aperture and the distal end portion of the contact tip. The internal gas diverter directs a flow of shield gas exiting the at least one aperture along the exterior surface of the contact tip.
Claims20
An arc welding apparatus comprising:
- a handle;
- a conductor tube attached to the handle;
- a welding cable that carries welding current, shield gas, and a welding wire, the welding cable being connected to the handle;
- and
- a consumable assembly attached to the conductor tube, the consumable assembly comprising:
- a nozzle assembly comprising a nozzle body, an insulator disposed within the nozzle body, and a nozzle insert disposed within the insulator, the nozzle insert comprising an internal gas diverter and a seating surface;
- and
- a contact tip disposed within the nozzle assembly, the contact tip defining a shoulder that engages the seating surface of the nozzle insert and the contact tip further comprising at least one aperture extending from an exterior surface into an internal cavity;
- and
- wherein the internal gas diverter directs a flow of shield gas exiting the at least one aperture along the exterior surface of the contact tip.
An arc welding apparatus comprising:
- a handle;
- a conductor tube attached to the handle;
- a welding cable that carries welding current, shield gas, and a welding wire, the welding cable being connected to the handle;
- and
- a nozzle assembly attached to the conductor tube and configured to secure a contact tip to the conductor tube, the nozzle assembly comprising:
- a nozzle body having a distal opening and an opposite proximal opening,
- an insulator disposed within the nozzle body, and
- a nozzle insert disposed within the insulator, the nozzle insert defining a longitudinal axis and having a proximal end portion, a distal end portion, and a central bore extending from the proximal end portion towards the distal end portion, the insert further comprising:
- an internal gas diverter disposed proximate to the distal end portion of the nozzle insert, the internal gas diverter defining a seating surface facing toward the proximal end portion and a profiled diverter orifice, wherein the profiled diverter orifice is defined by a surface facing toward the distal end portion of the body, the surface extending radially outward from the longitudinal axis along a length of the surface toward the distal end portion, the length of the surface extending distally from the central bore to the distal end portion.
An arc welding apparatus comprising:
- a handle;
- a conductor tube attached to the handle;
- a welding cable that carries welding current, shield gas, and a welding wire, the welding cable being connected to the handle;
- and
- a consumable assembly attached to the conductor tube, the consumable assembly comprising:
- a nozzle assembly comprising a nozzle body, an insulator disposed within the nozzle body, and a nozzle insert disposed within the insulator, the nozzle insert comprising a distal end portion, a proximal end portion, and an internal gas diverter disposed proximate to the distal end portion, the internal gas diverter comprising:
- a profiled diverter orifice having a surface facing toward the distal end portion and extending radially outward from a longitudinal axis of the nozzle insert along a length of the surface toward the distal end portion, and
- a seating surface facing toward the proximal end portion;
- and
- a contact tip disposed within the nozzle assembly, the contact tip defining a shoulder that engages the seating surface of the nozzle insert, the contact tip further comprising at least one aperture extending from an exterior surface into an internal cavity;
- and
- wherein the profiled diverter orifice directs a flow of shield gas exiting the at least one aperture along the exterior surface of the contact tip.
