    摘要: An electrode used in a plasma-arc torch has ridges formed on the side surface thereof for initiating a pilot arc. The required voltage for initiating a pilot arc is substantially reduced by employing this type of electrode. The ridges have much smaller radii of curvature which substantially enhance the local electric field strength responsible for creating the pilot arc discharge. The ridges are oriented substantially along the flow lines of the plasma gas so as to create the least disturbance. In one embodiment with spiral gas flow, this results in helically oriented ridges. In another embodiment with straight gas flow, the ridges are parallel to the longitudinal axis of the electrode.

    摘要: A bumper system includes a high-strength metal B-shaped beam with miter-cut end sections, a front center energy absorber, and a pair of energy-absorbing end pieces that nestingly engage front outer ends of the beam. By this arrangement, the bumper system with energy absorbers forms an impact system capable of providing good corner impact resistance. The energy-absorbing end pieces act as a low-cost and lightweight extension to the beam, and absorb energy so as to lessen intrusion and decrease the energy that is transmitted into the frame rails of the vehicle.

    摘要: Methods of forming an electrode for use in a plasma arc torch are provided that generally include forming an electrode body defining a proximal end portion and a distal end portion, forming a recess within the distal end portion, securing a slug within the recess of the distal end portion, creating a bore through the slug and the distal end portion of the electrode body, and securing an emissive insert within the bore. In another form, a hybrid electrode is provided, which is formed by the manufacturing methods of the present invention, and which includes an electrode body defining a cavity, a secondary body secured to the electrode body, and an emissive element secured within the bore and in contact with the secondary body and the electrode body, wherein the secondary body is not exposed to the cavity.
