Abstract:
A diffuser insert is provided for use with a welding diffuser and contact tip assembly comprising a diffuser with an interior chamber configured to receive a wire conduit that supplies electrode wire and a shielding gas used during a welding operation and a contact tip coupled to the diffuser and configured to receive electrode wire. The diffuser insert comprises a diffuser insert body configured to be disposed within the interior chamber of the diffuser, and further comprises an insert bore extending therethrough configured to receive electrode wire. An outer periphery of the diffuser insert has at least one surface feature configured to manipulate a flow of said shielding gas from within said interior chamber of the diffuser and out of exit passages to thereby direct said flow of shielding gas about a molten welding puddle formed during a welding operation.

Claim (Index 36):
A diffuser assembly for a welding torch; said diffuser assembly comprising:\n a diffuser body having a longitudinal axis extending from a first end to a second end of said diffuser body, said diffuser body having a wall portion defining an interior chamber extending along said longitudinal axis, said wall portion having,\n a first opening at said first end which is configured to permit a flow of a gas into said interior chamber, \n a plurality of second openings that extend through said wall portion to permit said flow of said gas to exit said interior chamber through said plurality of second openings to an outside of said diffuser body, said plurality of second openings symmetrically disposed on said wall portion, and \n a third opening at said second end to permit insert of a contact tip; and \n a diffuser insert positioned within said interior chamber where said diffuser insert along a longitudinal position of said diffuser insert overlaps with said second openings along an entire longitudinal length of said second openings, when viewed from a radial direction with respect to said diffuser body, wherein an outer surface of said diffuser insert has an axially extending feature to provide said flow of said gas to said plurality of said second openings, said axially extending feature comprising a tapered surface of said outer surface tapered away from the wall portion of said diffuser body at an angle, wherein said tapered surface extends axially to a longitudinal position of said plurality of second openings, and wherein said diffuser insert is secured in a press-fit relationship with said diffuser body.
