摘要： A method for spot-welding aluminum workpieces with copper electrodes that comprises the steps of: (a) dissolving copper and one or more alloying elements X to yield an alloy that increases the liquidus of Al when dissolved in molten Al, super heating the alloy of copper and one or more elements X that normally have little or nor solubility in copper at room temperature, such super heating being a temperature at which X is soluble in copper, X being selected from the group of Mo, Ta, V, and W, elements that form monotectic or peritectic phases with copper and aluminum devoid of an eutectic, X being present in an amount of 4-15% by weight of the copper; (b) rapidly cooling the alloy to room temperature to retain such elements in solid solution; (c) either concurrently or subsequent to step (b), forming the alloy as an electrode shape; and (d) passing current through the electrode shape to effect spot-welding of the aluminum workpieces when pressed thereagainst while extending the welding life of the electrode. Super heating and rapid cooling may be carried out by atomizing a melt of Cu and X with a pressurized gas that directs the spray onto a target for further cooling and eventual working or shaping.

摘要： The invention relates to ZrB.sub.2 /Cu composites, and more specifically to methods of making ZrB.sub.2 /Cu composite electrodes and methods of using ZrB.sub.2 /Cu composite electrodes. ZrB.sub.2 powder is contacted with a polymer and shaped to a desired form. The polymer is vaporized and the ZrB.sub.2 powder is sintered. The sintered ZrB.sub.2 is contacted with Cu and heated above the melting point of Cu which causes the Cu to infiltrate the ZrB.sub.2, forming the ZrB.sub.2 /Cu composite electrode.

摘要： A welding electrode for providing a significant improvement in the detrimental tensile residual stress condition on the root side of welds, especially on the inside wall of piping welds. The electrode has a tungsten alloy blade. The blade is made from sheets of tungsten alloy by cutting or stamping. The preferred shape of the blade is an isosceles triangle. The base of the flat triangular blade is secured in a slot formed in an electrode holder. The electrode holder is preferably T-shaped, with the shank of the holder being connected to a conventional welding torch. The holder is made of electrically conductive material, whereby the blade is coupled to the torch for producing an electric arc at the blade tip for welding. The blade is optionally covered with a ceramic coating to prevent arcing to the side walls of the groove formed between the parts being welded. A further option is to incorporate insulating stand-offs which protrude from both flat sides of the electrode blade. These stand-offs serve to maintain a minimum gap between the side walls of the welding groove and the flat sides of the electrode blade, thus preventing the ceramic coating from being scratched off during electrode travel relative to the groove.
摘要翻译：一种焊接电极，用于显着改善焊缝根部侧面的有害拉伸残余应力状况，特别是在管道焊缝的内壁上。电极具有钨合金刀片。刀片由切割或冲压的钨合金片制成。叶片的优选形状是等腰三角形。扁平三角形刀片的基部固定在形成在电极座中的槽中。电极座优选为T形，保持器的柄与常规焊枪相连。保持器由导电材料制成，由此刀片联接到割炬上，用于在刀尖处产生用于焊接的电弧。刀片可选地覆盖有陶瓷涂层，以防止在被焊接的部件之间形成的凹槽的侧壁起弧。另一个选择是结合从电极刀片的两个平面侧突出的绝缘支架。这些支架用于保持焊接槽的侧壁和电极刀片的平坦侧面之间的最小间隙，从而防止在电极相对于槽移动期间陶瓷涂层被刮掉。

摘要： Resistance welding electrodes and processes of using and of fabricating the same are provided. The electrodes have a base portion and an integral nose portion projecting therefrom, with the nose portion terminating in a welding tip face. The nose portion tapers inwardly between said base portion and said welding tip face with a concave profile taper such as a frustum of a vortical surface. The electrodes used may be made up of a conventional copper material having copper combined with one or more metals selected from the group consisting of chromium, zirconium, cadmium, cobalt, nickel, beryllium, tungsten, aluminum, tungsten carbide, iron, and molybdenum; or, may be made of essentially pure copper. The electrodes may be used in a welding process, which provides for a generally linear increase in current stepping with reduced or eliminated conditioning of the electrodes. The welding tip face has a convex curvature which may range between about a two inch and a eight inch radius of curvature, and which preferably has a radius of curvature of about four inches. Both male and female electrodes may be used with cooling recesses in the electrodes as well as an offset nose portion. The diameter of the welding tip face may be about equal to the length of the nose portion. The nose portion may be angled with respect to the base, and additionally may be offset. Fibrous grain structure may be formed which is at a non-normal angle with respect to the welding tip face to reduce cracking.

摘要： In apparatus according to the present invention, re-forming takes place in a single operation. The forming device contains a die extended by a hollow cylindrical die area and includes a punch which is surrounded by an outer punch which is advanced under the tension of a spring and fits into the hollow cylindrical die area. A conical centering area is located upstream of the hollow cylindrical die area. Used spot welding electrodes of different lengths and pronounced deformation can be restored several times with this forming tool.
