摘要： A workpiece may be heated with one or more induction heating coils coupled to an induction heating and control system. The heating is done in conjunction with a metal working operation, such as welding. The heating may be performed to remove coatings and the like before welding, to apply claddings and the like following welding, to allow for improved porosity of a weld bead, and so forth. Induction heating heads may be placed before or after a welding torch, and may be moved with or independently. One or more induction heating heads may be placed in pipe to be welded, such as on, in, or adjacent to an internal pipe claim that holds pipe during welding.

摘要： A welding method includes feeding a welding electrode axially from a welding torch, moving the welding electrode radially in a desired pattern with respect to a central axis of the welding torch by a motion control assembly within the welding torch, transmitting from control circuitry a signal corresponding to a position of the welding electrode relative to a weld joint or weld pool, advancing the welding torch or a workpiece to establish a weld, and transferring material from the welding electrode to a first location in an area of the weld pool. The welding electrode moves radially while feeding the welding electrode from the welding torch, the material from the welding electrode is transferred to the first location during a first cycle of the desired pattern, and the first location is controlled based at least in part on the signal.

摘要： Systems and methods are disclosed that provides a helical wire for use in welding applications. A torch can be adapted to form the helical wire from a straight wire and to provide the helical wire as a consumable electrode in a welding or cladding application. The helical wire can be, for example, solid, tubular, or seamless tubular. The torch concurrently forms the helical wire and provides welding current for the welding or cladding application.

摘要： Systems and methods for the manufacture of a solid wire using additive manufacturing techniques are disclosed. In one embodiment, a fine powdery material is sintered or melted or soldered or metallurgically bonded onto a metal strip substrate in a compacted solid form or a near-net shape (e.g., a near-net solid wire shape) before being turned into a final product through forming or drawing dies.

摘要： Apparatuses, systems, and/or methods relate to a welding system that provides a field former for use in welding applications. The welding system includes a welding torch that includes one or more coil windings through which flows current that forms a magnetic field. The magnetic field is concentric to the tool center point. An arc is formed between the electrode and a workpiece. The magnetic field forces the arc in a center of the welding torch or the one or more coiled windings.

摘要： Methods and apparatus to communicate via a weld cable are disclosed. An example weld circuit communications device includes a receiver circuit, a processor, and a local communications adapter. The receiver circuit to receive a communication via a weld circuit while current is flowing through the weld circuit or after the current has stopped flowing through the weld circuit, the communication including weld voltage feedback information measured at a device remote from a power supply and remote from the weld circuit communications device while the current is flowing through the weld circuit. The processor generates power supply control information based on the weld voltage feedback information. The local communications adapter transmits the power supply control information to control welding-type power output by a power converter to regulate a weld voltage to a weld voltage setpoint.

摘要： Hybrid manual and automated welding systems and methods are described. A hand-held welding tool is manually positioned to engage a workpiece. The hand-held welding tool includes a motion device that is configured to automatically move a contact tip or a welding heat source during a welding operation after a manual triggering. A welding arc is automatically and repeatedly turned off and on to make a string of overlapping and equally spaced spot welds while the contact tip or the welding heat source moves from the first position to the second position.
