Welding cameras, welding helmets, welding masks, and associated display systems are described herein that utilize darkening or attenuating filters in conjunction with long-exposure imaging to capture flicker-free video of a welding process. Example embodiments include one or more of a darkening filter, an image sensor to capture long-exposure images as frames of a video, an optical image stabilization subsystem, a data storage to store video, and an electronic display to display the video. For example, captured images may be displayed on an electronic display within the welding mask without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different images to each eye of the operator to provide a stereoscopic video feed.

Described herein are examples of smart welding helmets having a plurality of functions that go beyond conventional welding helmets. For example, a smart welding helmet may be configured to detect if/when the helmet surpasses one or more temperature thresholds, which may alert an operator if they have been welding too close and/or for too long. Other example smart helmet functions may include the ability to display (and/or otherwise output) feedback/guidance and/or welding information, as well as communicate with appropriate personnel. In some examples, the smart welding helmet may be configured to selectively enable/disable certain functions of the smart welding helmet to accommodate the needs of a particular operator and/or groups of operators.

A welding helmet having a filter arrangement is disclosed. The welding helmet is provided with a main filter and at least one auxiliary filter separate from and positioned next to the main filter. The at least one auxiliary filter comprises an electro-optic element adapted to attenuate the transmission of optical radiation incident on the auxiliary filter.

A welding helmet (1) with a head suspension system, a protective shield (2) and a movable visor (3). The protective shield forms a see-through window. The welding helmet further has a first neck shield (6). The protective shield forms a lower end at which the first neck shield is removably attachable.
