Abstract

Presented herein are techniques for activating auxiliary features of an arc process system when a controller determines a torch is in a user's hand. The controller will determine, via a motion sensor in the torch, when the torch moves and/or a user picks up and handles the torch. Once the system detects motion of the torch, the system may automatically activate auxiliary features of the system in anticipation of arc initiation.

The spacing of the supports from each other further defines a series of pathways configured to receive the forks of both a forklift and a pallet jack. The pallet may be configured to receive the forks of a forklift and a pallet jack from multiple different directions. The forks of the forklift may be received by the pallet such that the forks are oriented either perpendicular or parallel to the sides of the pallet. The forks of the pallet jack may be received by the pallet such that the forks are offset from being either perpendicular or parallel to the sides of the pallet.

The method includes arranging a first twin SAW head in close proximity to a second twin SAW head, delivering electroslag flux to a surface of a workpiece to create a layer of electroslag flux atop the workpiece, directing two first consumable wires through the first twin SAW head towards the surface of the workpiece, directing two second consumable wires through the second twin SAW head towards the surface of the workpiece, introducing the two first consumable wires and the two second consumable wires into a molten slag pool formed on the surface of the workpiece to melt the two first consumable wires and the two second consumable wires via resistive heating, and translating the first twin SAW head and the second twin SAW head together to form a cladded deposit on the workpiece.

Abstract

A method and system for electroslag strip cladding (ESSC) of rail heads without preheating utilizing twin electroslag strip welding techniques. The twin ESSC techniques include depositing a layer of wear and corrosion resistance cladding material onto the entire running surface of the rail head at a relatively fast welding speed of approximately sixty cm/minute with less than one cm/meter of distortion. The welding speed is achieved by moving a twin ESSC welding head along a rail, with the running surface of the rail head facing upward, or advancing a rail through a space under the twin ESSC welding head, with the running surface of the rail head facing upward, while cladding material is deposited continuously onto the running surface of the rail head.

The stable arc phase comprises the steps of continuously adjusting the feed speed of the hot wire and continuously adjusting the feed speed of the cold wire. The invention also relates to a welding apparatus (1) for carrying out the method. The welding apparatus comprises a hot wire feeding means (150), a contact means (2), a cold wire feeding means (35) and a control unit (31). The control unit is adapted to control said hot wire feeding means to feed the hot wire at a constant feed speed during the initial sub-phase, feed the hot wire at a constant feed speed during the main sub-phase and to continuously during the stable arc phase adjust the feed speed of the hot wire. The control unit is adapted to control said cold wire feeding means to feed the cold wire at a constant feed speed during the main sub-phase and continuously during the stable arc phase adjust the cold wire feed speed.

Various embodiments may be generally directed to a welding system that monitors an output of the welding system to determine if an output arc should be extinguished or maintained. The welding system can compare an arc voltage output to a voltage threshold and a temporal threshold. When the arc voltage output exceeds the voltage threshold in an uninterrupted manner for the duration of the temporal threshold, an output weld current can be stopped. In turn, the output arc can be broken or extinguished. After a predetermined amount of time, the power source can be re-engaged to prepare for re-ignition of another arc. By tracking the amount of time the arc voltage output exceeds the predetermined threshold, a probability of unwanted arc outs can be reduced or minimized while still providing quick and reliable arc breaking when desired.

Abstract

The flash removal unit presented herein is suitable for a friction stir welding (FSW) head and includes a blade and an annular body. The blade removes flash created by a FSW tool during FSW operations. The an annular body defines a flash capture area around the blade and is configured to at least temporarily retain the flash removed by the blade within the flash capture area. The flash removal unit may also define a flow path along which the flash can be suctioned away from the flash removal unit.

Abstract

A wire feeder includes an exterior housing and in interior housing that creates an interstitial spaced that is disposed between the exterior and interior housing. This housing structure reduces weight of the wire feeder while maintaining the structural rigidness required of a wire feeder. This housing structure also promotes improved cooling features for the wire feeder and the components disposed within the wire feeder. The exterior housing may be constructed of a materials that reduces the likelihood of being damaged. The wire feeder may be further equipped with a strain relief device for the incoming supply cables, and an interchangeable cable connector. The wire feeder may also be equipped with removable wire guides for the wire feeder mechanism that are toolless. The wire feeder may be equipped with accessory storage and attachment features, as well as a cost reduced repositionable control panel.

Abstract

The present application relates to an arc welding arrangement and an electric arc welding method to be used with the arc welding arrangement. The arc welding arrangement comprising a first power source, a first electrode connected to say first power source, and a second electrode, said first electrode being adapted to generate a weld pool via a first electric arc present within a first arc region. The second electrode is operated at welding parameters adapted to ensure that excess energy from at least said first electrode is required to maintain said second arc ignited. The method comprises the step of feeding said second electrode so that it is allowed to consume excess energy from said first electrode to maintain said second arc ignited.

Abstract

A transportable spool carrier includes a spool hub configured to receive a welding wire spool thereon. A handle is disposed a distance above the spool hub greater than the radial size of the spool hub such that the welding wire spool is transportable via the transportable spool carrier. The handle is vertically aligned with the longitudinal center portion of the spool hub axis to align the handle with a center of gravity of the welding wire spool when the welding wire spool is coupled to the transportable spool carrier. The transportable spool carrier may include two spaced feet configured to support the welding wire spool on a surface when the transportable spool carrier is decoupled from the frame. The spool hub may include an expandable cylinder that, when radially expanded the welding wire spool is locked to the spool hub.
