  • Publication number: 20140042140
    Abstract: A double-sided tribrid welding technique and apparatus for root pass welding of narrow groove welds. The welding technique utilizes three welding devices. A welding apparatus on a backside of the weld joint may strike an arc on the backside of the weld joint; a welding apparatus on a narrow groove side of the weld may strike an arc within the narrow groove weld joint, while the remaining welding apparatus is a laser that can help establish a keyhole as a common pool of molten metal at the root without burning through the root. Once the arcs are struck substantially simultaneously and the laser is energized, the welding heads move simultaneously, the arc welders assisting in maintaining pre-heat temperature, while minimizing distortion and cracking. Adjusting arc weld parameters provides deformation on completion of the root pass so as to compensate for distortion due to metal shrinkage in subsequent passes.

    Abstract: Systems and methods for determining that a consumable welding package has been, or may have been, replenished in a high production welding environment and that a tracked weight value of the consumable welding package should be reset. An operator of a welding system can be notified that a consumable welding package may have been replenished and, therefore, that the weight value of the consumable welding package may need to be reset in the welding system. Alternatively, the weight value of the consumable welding package in the welding system may be automatically reset when the welding system has determined that the consumable welding package has been replenished.

  • Publication number: 20140021185
    Abstract: Systems and methods for producing dowel baskets from dowel side frames and transverse dowel rods. The dowel side frames are introduced at a top location of the production system, where there is initially introduced a first dowel rod and subsequently, with successive stepwise advancements, the remaining dowel rods are introduced. The dowel side frames with the dowel rods advance on guides that may rotate the dowel side frames relative to the axes of the longitudinal wires so as to impart a desired inclination angle ? relative to the rods. In following, with continuous stepwise advancements, the dowel rods are alternately welded, each to one of the opposed dowel side frames. Transverse wires are welded on the longitudinal wires to impart rigidity to the dowel basket. Subsequently, mass-produced dowel baskets may be stacked in groups.

  • Patent number: 8461472
    Abstract: A welding machine that includes a machine frame having an opening permitting access to an interchangeable tooling module installed on the machine. The welding machine includes one or more light curtains covering the opening to disable operation of one or more welding stations on the tooling module if the light curtain is breached by an operator, robot, or other object. The welding machine includes a selector arm attached to the machine frame at a location between a first end and a second end of the opening. The selector arm can be moved into and out of position at the opening to selectively define either a single light curtain across the opening or a pair of adjacent light curtains that permit separate operation and access to separate welding stations behind each of the two light curtains.

  • Patent number: 8450646
    Abstract: A retaining head for a MIG welding device includes a contact tip mounting end, an opposite retaining head mounting end, and a throughbore extending from one of the ends to the other end. A deflector is disposed along the throughbore and is adjustable for imparting a bend in welding wire passing through the throughbore. The deflector provides a straight wire contour for the welding wire that is fed out of the welding torch, while maintaining sufficient contact force between the welding wire and the contact tip. The deflector also reduces the effect of wire twist on the contact point between the welding wire and the contact tip.

    Abstract: A turntable assembly for performing welding or other operations in a pivotably-mounted J-lay tower is disclosed. The assembly includes an annular turntable supported by a base frame to turn about a pipe string in use and a tilt-compensating mechanism acting on the base frame to level the turntable as the tower pivots in use. The tilt-compensating mechanism includes at least one support that is driveable up and down with respect to the tower. In the embodiment disclosed, the support is a carriage movable along an upright track that pivots with the tower.

  • Patent number: 8445816
    Abstract: A welding power supply includes a controller that automatically monitors the presence or absence of one or more modules connected to or installed into the welding power supply. The controller automatically turns on or off the power supply functions related to which optional modules are present. The controller populates various end-user interface menus based on which optional modules are installed. The controller uses software and/or hardware to make the determination. The optional module(s) themselves include circuitry which allows the controller to recognize when the optional module has been installed and what functions the installed optional module is capable of performing. The circuitry of the optional module(s) allows the optional module(s) to communicate with the controller. In this way, the end-user will not have the options of selecting a process on the user interface menus that is not available because the required equipment has not been installed.

    Abstract: A mobile welding system has a mobile base for traversing a surface, proximate to a region to be welded. The mobile welding system has a lift, coupled to the mobile base and to a platform for moving the platform vertically proximate to the region. The lift is disposed between the platform and the mobile base. The mobile welding system has a robotic arm coupled to the platform. The mobile welding system has a welding torch, disposed on a first end of the robotic arm, for welding the region. The mobile welding system has a controller configured to cause the welding torch to move proximate to the region by causing at least one of the mobile base, the lift, and the robotic arm to move in at least one direction.
