Systems and methods to aid a welder or welding student. A system may provide a real-world arc welding system or a virtual reality arc welding system along with a computerized eyewear device having a head-up display (HUD). The computerized eyewear device may be worn by a user under a conventional welding helmet as eye glasses are worn and may wirelessly communicate with a welding power source of a real-world arc welding system or a programmable processor-based subsystem of a virtual reality arc welding system.

A welding shield with a welding tool in combination with an adjusting device for adjusting position of a welding tool tip. The welding shield comprises a welding shield body having an outer wall, a weld viewer, and a fastening device for securing the welding tool. The adjusting device includes a platform base comprising a floor member, a wall member surrounding the floor member and a sub-floor slot formed in the floor member. The sub-floor slot has a sub-floor surface spaced inwardly from a floor surface of the floor member. The outer wall of the protective welding shield is configured to be mounted to the floor member of the platform base so that a bottom edge of the welding shield body is disposed within the wall member of the platform base and the welding tip of the welding tool faces the sub-floor slot.

Automatically recognizing interchangeable torch components, such as consumables, for welding and cutting torches includes adding one or more passive markings to a surface of an interchangeable torch component. Then, the interchangeable component can be recognized by a torch assembly including a torch body and one or more imaging devices or by a system including the torch assembly and a power supply. The torch body has an operative end configured to removably receive the interchangeable torch component. The one or more imaging devices are positioned to optically acquire an image of or image data representative of the one or more passive markings included on the interchangeable torch components so that a processor can determine if the one or more interchangeable components are genuine.

An example robotic tool holder includes an actuator that is disposed within a housing and configured to hold a tool. The housing and the actuator are in contact via dowels to limit movement of the actuator toward a distal end of the housing. Ones of the dowels that are in contact are in line contact and the ones of the dowels that are in contact are in a triangular geometry. The pressure plate is in line contact with the actuator within the housing around a circumference of the pressure plate. The springs are in contact with the pressure plate to bias the actuator toward a proximal end of the housing via the pressure plate. The springs are in contact with the mounting plate opposite the pressure plate. The sensor switch detects a shock force on the actuator and outputs a signal in response to the shock force.

The disclosure includes a welding cup system comprising a tube having an open top, an open bottom, a sidewall extending between the open top and the open bottom, and an open channel. The open channel may extend through an interior portion of the tube from the open top to the open bottom. The open top may be arranged and configured to slideably couple to at least a portion of a torch assembly. The open channel may be arranged and configured to allow gas to flow from the open top to the open bottom, and allow a welding electrode to extend through the open channel from open top towards the open bottom. The welding cup system may have a side profile that may define an asymmetrical shape.

Device (1) for the provision of electric power, wherein the device (1) comprises: at least one integrated temperature sensor (3-1, 3-2) which detects an operating temperature progression of at least one component (2-1, 2-2) of the device (1) and a monitoring unit (5) which, on the basis of the at least one detected operating temperature progression and the adjusted power, monitors the operating state of a device cooling arrangement of the device (1).

The present disclosure is directed to a system and method for preventing damage to one or more components of the gas turbine engine during a repair procedure. The method includes locating one or more gaps of one or more components of the gas turbine engine in the vicinity of the defect. Further, the method includes filling the one or more gaps with a filler material so as to prevent arcing over the gaps during repair. Thus, the method also includes applying an electrical discharge to the defect.

A welding system includes a power supply configured to generate a welding waveform. A wire feeder conducts the welding waveform to a wire electrode, and includes a drive motor that drives the wire electrode bidirectionally, a motor current sensor that senses a current level of the motor, and a controller that receives a current level signal from the motor current sensor and controls operations of the motor. A welding current sensor senses welding current level, and a welding voltage sensor senses welding voltage level, and the sensors are located with the power supply or the wire feeder. The controller is configured to determine a contact event between the wire electrode and a non-workpiece object based on the current level signal from the motor current sensor and one or both of the welding current level and the welding voltage level, and automatically retract the wire electrode upon determining the contact event.

A tip attached to a torch barrel of a welding torch includes: a cylindrical tip body attached to the torch barrel; a cylindrical orifice member fitted on an outer circumference of the tip body; an orifice-member support nut detachably attached to a front end outer circumference of the tip body and supporting the orifice member on the outer circumference of the tip body; a cylindrical contact tip detachably attached to a front-end inner circumference of the tip body; and an annular shield member disposed between the tip body and the contact tip. The shield member has an outer diameter set no less than a front-end outer diameter of the orifice-member support nut but no more than an outer diameter of the orifice member. A welding robot including the welding torch and a welding system including the welding robot and a welding power supply are also disclosed.

A portable welding ground clamp attachment system used to attach a welding ground clamp (also called a work clamp or work cable) of an arc welder to a workpiece to be welded. The system is particularly useful in establishing positive connections between a work cable and extended lengths of pipe.
