  • Patent number: 9422674
    Abstract: An improved in-track welder eliminates conduction path force members and employs separate bridging current path conductors for DC welding of rail ends. The enhancement allows for an increased closure distance, thus improving cold-weather operations. An increased allowable distance between conduction contacts allows for the incorporation of an internal shear member for more efficient finishing of welds. The force members may be optimized for strength rather than electrical properties, and are comprised of relatively small diameter alloy steel rods.

    Abstract: A welding fixture clamp includes a stationary clamp jaw having a first guide surface and a pivotal clamp jaw having a second guide surface. The second guide surface slides relative to the first guide surface as the pivotal clamp jaw pivots about the pivot axis. Side shields are secured to one of the pivotal clamp jaw and the stationary clamp jaw to extend over the other one of the pivotal clamp jaw and the stationary clamp jaw to shield the first guide surface and the second guide surface from weld splatter and debris. A pivot pin connects the side shield to the stationary clamp jaw and operatively connects the pivotal clamp jaw to the stationary clamp jaw to pivot about the pivot axis.

  • Patent number: 8608048
    Abstract: A method of room-temperature bonding a plurality of substrates via an intermediate member, includes: forming the intermediate member on a surface to be bonded of the substrate by physically sputtering a plurality of targets; and activating the surface to be bonded by an ion beam. In this case, it is preferable that the target composed of a plurality of types of materials is physically sputtered. Since the materials of the intermediate member are sputtered from the plurality of targets arranged in various directions from the surface to be bonded of the substrate, the intermediate member can be uniformly formed on the surface to be bonded. Further, since the intermediate member is composed of the plurality of types of materials, the room-temperature bonding of substrates difficult to bond together when an intermediate member is composed of a single type of material can be performed without heating and excessively pressing the substrates during bonding.

    Abstract: Weld stress compensation system and method comprising: 1) a primary tube/rod clamp; 2) a secondary tube/rod clamp for selectively and accurately, angularly positioning the secondary tube relative to the primary tube. The secondary clamp is transferable while a secondary tube/rod is clamped therein to: 3) a saddle cutting fixture to produce a concave, relieved portion in the end of the secondary tube/rod with flanking flanges that fit precisely over the primary tube at the join intersection; 4) a miter-cut fixture for miter cutting of tube/rod ends to fit flat surfaces or conversely-cut tubes/rods for angular joins; and 5) a welding fixture for precise angular positioning of a miter cut tube/rod to a deck, wall, or stair plate. The primary clamp includes an adjustable pressure pad that applies pressure to the side of the primary tube opposite the secondary tube weld join line thereby preventing warping due to weld stresses.

  • Publication number: 20130260534
    Abstract: A method is provided for bonding a semiconductor chip to a packaging substrate while minimizing the variation in the solder ball heights and controlling the stress in the solder balls and the stress in the packaging substrate. During the solder reflow, the warp of the packaging substrate, including the absolute warp, thermal warp, and substrate to substrate variations of the warp, is constrained at a minimal level by providing a clamping constraint to the packaging substrate. During cool down of the solder balls, the stresses and strains of the solder joints are maintained at levels that do not cause tear of the solder joints or breakage of the packaging substrate by removing the clamping constraint. Thus, the bonding process provides both uniform solder height with minimized solder non-wets and stress minimization of the solder balls and the packaging substrate.
