Various welding systems including a welding torch assembly are provided. The welding torch assemblies may include a welding torch adapted to be utilized in a welding operation to establish a welding arc between the welding torch and a workpiece. The welding torch assemblies may also include a temperature sensing system integral with the welding torch and adapted to sense a temperature of the workpiece.

A supplementary circuit for process supply lines of a welding torch or cutting torch has at least one connection device to a welding current source arranged on it, wherein electrical energy and other media are conveyed to the welding torch or cutting torch via the connection device and via a process supply line that is preferably held in a hose pack of the welding torch or cutting torch. Electrical energy for operating a peripheral device, such as a sensor, a drive unit or a controller for the drive unit, is branched or tapped off from at least one electrical process supply line without significantly affecting the electric arc process. The supplementary circuit provided for branching or tapping off the electrical energy is coupled in parallel onto the welding current circuit. This coupling is based on direct ohmic contact or on a galvanic coupling.

Devices and methods to assist wire arc additive manufacturing (WAAM) are provided. A non-contact, multidirectional synchronized ultrasonic device can include multiple ultrasonic probes mounted on a nozzle of a WAAM robotic arm. The probes can include one normal probe and a plurality of lateral probes configured to rotate on a parabolic frame. The ultrasonic probe in the normal direction can act by its continual high-frequency oscillation in the arc plasma to enhance the arc push force, while the lateral probes can act on the shape of both sides of the deposit. The combined effect of the probes can generate ultrasonic waves and cavitation in the molten pool.

The invention relates to a method for conducting gas in a gas-cooled plasma torch wherein the plasma torch has a plasma torch body which holds an electrode with an open end and a closed end. A cavity extends from the open end in the direction of the closed end, and which, with a spacing in an axial direction, holds a nozzle by means of a nozzle holder. The nozzle has a central opening with an upstream inlet end, into which the electrode projects, and with an outlet end with a nozzle bore and is surrounded by a nozzle cap and/or a nozzle protection cap. The plasma torch body has an opening for a gas feeder, which opening is fluidically connected to a cooling tube which projects into the open end of the electrode.

A welding torch maintenance apparatus and a welding tip changer are described. The welding torch maintenance apparatus and the welding tip changing apparatus each comprise a first gripping means for fastening the welding torch/diffuser so that the nozzle/welding tip is aligned with the rotational axis, a second gripping means for holding the nozzle/welding tip, the second gripping means rotates about the rotational axis to remove the nozzle/welding tip, and moves along the rotational axis. A drive means is provided for rotating the second gripping means, and a lift system is provided for moving the second gripping along the rotational axis. The welding torch maintenance apparatus further includes a cleaning means which enters the nozzle at the distal end and cleans an interior of the nozzle.

Apparatuses, systems, and/or methods for providing an induction heating system are disclosed. The induction heating system includes an induction power supply and an induction heating tool configured to receive induction-type power from the induction power supply through one or more ports. The ports may be part of the induction power supply and/or an associated junction box. The induction heating tool may include a heating coil attached to one or more plugs via one or more cables. The ports of the induction power supply and/or junction box are configured to receive the plugs of the induction heating tool. A communication device may be positioned adjacent the ports. The communication device may be configured to read data from one or more memory devices of the induction heating tool (e.g., in/on the plugs) via close proximity communication.
