摘要： Systems, methods, and apparatus to preheat weld wire are disclosed. An example contact tip includes: an inner bore configured to conduct current to a consumable welding electrode; screw threads on an exterior of the contact tip; and a head opposite the screw threads on an exterior of the contact tip to enable threading and dethreading of the contact tip.

摘要： An induction heating system includes interchangeable secondary induction heating assemblies and/or secondary induction heating coil flux concentrators that are specifically configured for the particular type of weld being created and/or the particular weld joint where the weld is created. For example, the secondary induction heating assemblies and/or secondary induction heating coil flux concentrators may have specific physical configurations (e.g., shapes, contours, etc.) and/or include specific materials (e.g., ferrites) that are well suited for the particular type of weld being created and/or the particular weld joint where the weld is created. In certain embodiments, a robotic positioning system may be configured to move the secondary induction heating coil to an induction heating coil changing station to, for example, detach the secondary induction heating coil, and attach another secondary induction heating coil, thereby facilitating different secondary induction heating coils to be used for induction heating of different types of welds, for example. In addition, in certain embodiments, the robotic positioning system may be configured to move the secondary induction heating coil to the induction heating coil changing station to, for example, detach the secondary induction heating coil flux concentrator, and attach another secondary induction heating coil flux concentrator.

摘要： Disclosed welding-type systems and methods are directed to employing a wire feeder for feeding an electrode wire from a wire source in a welding system. The wire feeder includes one or more drive rolls to advance the electrode wire by contact force. In disclosed examples, a contact force on the wire from the drive rolls is adjustable. In some examples, the system includes a controller to receive a feedback signal corresponding to the contact force. The controller commands an actuator or other mechanism to adjust the contact force on the wire, such as by adjusting a position of the one or more drive rolls in response to the contact force falling outside a range of threshold contact force values.
