Abstract: An end assembly for use with a welding device having a contact tip, a diffusor body, and a gooseneck. The contact tip has a convex end surface that contacts and mates with a concave end of the diffuser body. The diffuser body forms a blind bore forming central web and a series of passageways. A longitudinal passageway segment is formed in the contact tip parallel with the central longitudinal electrode bore of the contact tip. A second passageway segment joins the first longitudinal passageway segment. When the contact tip is affixed to the diffuser body, a chamber is formed at the base of the contact tip communicating with the diffuser body passageways. Shielding gas that flows into the diffuser body passes through the web passageways into the chamber and through the first and second passageways of the contact tip to provide shielding gas to the weld site and cool the contact tip during welding operations.

Abstract: A system and method for more consistent joule heating of a material blank to a desired temperature. An electrical terminal delivers a current to an end portion of the blank. The terminal has a heat sink effect which would otherwise prevent the end portion from reaching the desired temperature. An active thermal buffer element is interposed between the terminal and the end portion. The buffer element includes a first surface which abuts the end portion and a second surface which abuts the terminal. The buffer element is joule heated with the blank, and a temperature gradient is created across the buffer element such that the first surface is at the desired temperature and the second surface is at a lower temperature due to the heat sink effect of the terminal. The buffer element thereby compensates for the heat sink effect and allows the end portion to reach the desired temperature.
