A welding helmet system is provided. The welding helmet system includes a protective shell and a welding display system. The welding display system is configured to be removably coupled to the protective shell. The welding display system is configured to receive data from a sensor, and to display a welding metric derived from the sensor via the image generation system.

Provided is a welding protector which includes a face shield configured to protect a face of a welder and an auxiliary shield disposed adjacent to one edge of the face shield. The auxiliary shield includes a plurality of portions which overlap each other in a first mode and move to reduce an overlapping area when switching from the first mode to a second mode.

A welding information providing apparatus is disclosed. The welding information providing apparatus includes a main body worn by a user, a camera unit provided to an outside of the main body and including at least one camera obtaining welding image frames for a welding process, an image generating unit provided to inside the main body and generating a welding image based on the welding image frames, a display unit displaying the welding image provided from the image generating unit toward a user, a processor for controlling the image generating unit to generate the welding image based on the welding image frames, and a power supply unit provided to the main body and supplying a driving power to at least any one of the camera unit, the image generating unit and the processor.

A method includes receiving welding data corresponding to a welding session completed with a welding system, receiving a selected location from an operator, and displaying on a display one or more quality characteristics of the welding session corresponding to the selected location. The welding data includes welding parameters and quality characteristics corresponding to a plurality of points along a path of the welding session. The welding parameters include a work angle of a welding torch, a travel angle of the welding torch, a contact tip to work distance, a travel speed of the welding torch along the path of the welding session, an aim of the welding torch, or any combination thereof. The quality characteristics include porosity, undercut, spatter, underfill, overfill, or any combination thereof. The selected location corresponds to a point of the plurality of points along the path of the welding session.

A protector for a welder includes a main body configured to cover a face and eyes of an operator; a darkening filter arranged in a front side of the main body and configured to protect the eyes of the operator; an image generator arranged in the main body and configured to generate image light; an optical path bender configured to change a proceeding path of the image light; and a combiner configured to generate a virtual image on an outer portion of the main body by projecting the image light, and arranged adjacent to the darkening filter.

A welding helmet system is provided. The welding helmet system includes a protective shell and a welding display system. The welding display system is configured to be removably coupled to the protective shell. The welding display system is configured to receive data from a sensor, and to display a welding metric derived from the sensor via the image generation system.

A welding lens includes a variable light transmission shutter that automatically darkens in response to light emitted from a source. An intensity of the emitted light is sensed by a photo-sensor located on a front face of the welding lens. Internal circuits located within a housing of the welding lens receive data from the photo-sensor and correspondingly darkens or lightens the variable light transmission shutter based on the intensity of the light. The housing is 50.80 mm in width and 107.95 mm in length to fit in corresponding welding helmets and the housing is made from stainless steel to reflect infrared radiation that would otherwise overheat the internal circuits within the welding lens.

Described herein are examples of weld tracking systems implemented via a welding helmet. The welding helmet includes weld tracking sensors configured to allow the welding helmet to track a welding-type tool and/or an arc generated by the welding-type tool. The welding helmet also includes helmet tracking sensors configured to allow the welding helmet to track its own position and/or orientation relative to a reference point in the welding environment. By tracking itself as well as the welding-type tool and/or arc, the welding helmet can differentiate between its own movement, and movement of the welding-type tool and/or arc. By implementing the weld tracking system in the welding helmet, the weld tracking system becomes portable and usable outside of the usual fixed confines of weld tracking systems.

Welding headwear comprises one or more image sensors, processing circuitry, and a display. The image sensor(s) are operable to capture an image of an unpowered weld torch as the torch passes along a joint of a workpiece to be welded. The processing circuitry is operable to: determine, through processing of pixel data of the image, one or more welding parameters as the torch passes along the joint to be welded; generate, based on the one or more welding parameters, a simulated weld bead; and superimpose on the image, in real time as the torch passes along the joint, the simulated weld bead on the joint. The display is operable to present, in real time as the torch passes along the joint, the image with the simulated bead overlaid on it.

A gas nozzle for the outflow of a protective/shielding gas stream from a gas outlet of the gas nozzle having a gas distributor/diffuser section has a double-walled configuration at least in a partial area of the gas distributor/diffuser section in order to create a flow space for the protective/shielding gas stream. The invention also relates to a torch neck and to a method for thermally joining at least one workpiece, in particular for arc joining, preferably for arc welding or arc brazing/soldering, with an electrode which is arranged in the torch neck or with a wire for producing an arc between the electrode or the wire and the workpiece, and having a gas nozzle for the outflow of a protective/shielding gas stream from a gas outlet.
