A display system for a welding helmet that includes a darkening filter layer, a high-dynamic range (HDR) camera system to capture an HDR light field, and an optical image stabilization subsystem. Captured images are displayed on an HDR electronic display within the welding helmet without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different HDR images to each eye of the operator.

A welding gun for welding a welding stud to a substrate in a welding direction is provided, comprising a holding device for holding the welding stud during a welding operation, wherein the welding stud has a contact surface which is intended to contact the substrate before and/or during the welding operation, further comprising a stud lifting device for conveying the holding device against the welding direction to an immersing start position, further comprising a stud immersing device for conveying the holding device from the immersing start position in the welding direction, further comprising a bearing element having a bearing surface for supporting the welding gun on the substrate, and further comprising a device for automatically adapting the immersing start position relative to the bearing surface in the welding direction.

A process is provided for welding an assembly of a first tubular component and a second tubular component, the first and second tubular components having first and second cylindrical portions, respectively. The process uses a pressing jig, a pressing tool, a welding jig and a welding head. The process includes: positioning the first tubular component with respect to the pressing jig; clamping the first tubular component against the pressing jig; freely fitting the second cylindrical portion into the first cylindrical portion, the two cylindrical portions being substantially coaxial; placing the second component with respect to the first cylindrical portion and the pressing jig; tightening the second tubular component against the pressing jig; aligning the two fitted cylindrical portions with the pressing tool; and pressing by plastic deformation the first and second cylindrical portions. The first and second pressed tubular components form a rigid assembly, with the two fitted and pressed cylindrical portions defining a fitting and a joint. Additional steps include: positioning the rigid assembly with respect to the welding jig; clamping the rigid assembly against the welding jig; and welding by positioning and orienting the welding head repeatably with respect to the fitting and the joint, where the rigid assembly is positioned with respect to the welding jig along one or more surfaces belonging exclusively to the first component in the pressed state.

Methods and apparatus to provide visual information associated with welding operations are disclosed. An weld training system includes a display, a camera, a communications device, and a welding helmet. The communications device communicates with welding equipment. The welding helmet has a view port. The communications device is configured to hold the camera, the communications device, and the display such that, when the welding helmet is worn by a wearer, the display is viewable by the wearer, the camera has a view through the view port such that the display displays to the wearer images taken by the camera through the view port and displays a simulated object generated based on information received from the welding equipment via the communications device.

Systems and methods for setting welding parameters are provided. For example, in certain embodiments, a method includes receiving an input relating to a change in a parameter of welding power of a welding system via a welding system interface. The method also includes displaying a graphical representation of an acceptable range of values for the parameter of the welding power on a display device of the welding system interface, wherein the acceptable range of values is based on other parameters of a welding process being performed by the welding system. The method further includes constraining subsequent manual inputs relating to changes in the parameter of the welding power to the acceptable range of values.
