摘要： A method of welding stainless steel, such as a stainless steel end plug into a stainless steel nuclear fuel rod is disclosed. The welding process has a reduced arc wander and deeper arc penetration. A treated welding electrode for practicing the method also is disclosed. A layer of stainless steel is placed on the working arc discharge end of a nonconsumable tungsten arc welding electrode before welding. The stainless steel coating on the electrode reduces arc wander and permits deeper arc penetration. Approximately 0.001 to 0.005 inches of stainless steel is placed on the working arc discharge end of the electrode. The electrode coating can be formed by positioning the working arc discharge end of the electrode into close proximity to a grounded piece of stainless steel and then electrically shorting the electrode to the stainless steel so that the working arc discharge end sticks to the stainless steel. The working arc discharge end of the electrode is broken from the stainless steel so that a layer of stainless steel remains thereon.

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： A male spot welding electrode includes a weld end portion having a generally flat contact surface and a tapered mounting portion containing an inlet bore. The inlet bore communicates with an internal cavity, containing cooling fins, for coolant fluid flow. The diameter of the internal cavity is made larger than the diameter of the inlet bore in order to maximize the cooling surface for the dissipation of heat generated during repeated welding operations. The male spot welding electrode is produced from a single billet of copper material through a process of back-extrusion and swaging.

摘要： A method of making a welded can body wherein the opposite marginal edge portions of a metallic blank are overlapped to form a can body preform with an overlapped portion, and then the overlapped portion is electric-resistance mash-seam welded by using a pair of wire electrodes abutting on both the surfaces of the overlapped portion. At least one of the pair of the wire electrodes is formed with a flat main portion and a marginal projection including a slope contiguous to the flat main portion on the surface thereof, which surface is adapted to abut on the surface of the overlapped portion. The overlapped portion of the can body preform is fed in between the pair of wire electrodes such that the edge face of one of the marginal edge portions may be positioned on an area of the flat main surface portion in the vicinity of the slope or be positioned on the slope, allowing the marginal edge beside the edge face to flow outwardly in the circumferential direction of the can body preform along the slope during the welding.
