Problems solved by technology

Furthermore, such protective lenses do not allow the user to see the thermal or infrared signature of the welding arc, weld pool, or surrounding metal at all
Additionally, users who require corrective lenses are disadvantaged when using conventional helmets and are limited to several "cheater" lenses that provide a certain degree of magnification

Embodiment Construction

[0013] Embodiments of the present invention pertain to systems, methods, and apparatus that provide dual-spectrum (eg, visible and infrared), real-time visual, enhanced visibility of arc welding signatures during an arc welding process. According to certain embodiments of the present invention, such capabilities are provided in a dual-spectrum welding helmet worn by a user performing the welding process.

[0014] As used herein, the term "physically integrated" means "disposed on", "is an integral part of" or "attached to" (with or without ability to be subsequently detached). As used herein, the term "real-time" refers to effectively maintaining the temporal characteristics of the imaged welding process scene with minimal or substantially imperceptible delay between image capture and display.

[0015] In this paper, the following combines Figure 1-Figure 7 The details of various embodiments of the invention are described. figure 1 is an illustration of a first exemplary e...

Abstract

Arc welding systems, methods, and apparatus that provide dual-spectrum, real-time viewable, enhanced user-discrimination between arc welding characteristics during an arc welding process. Welding headgear (110) is configured to shield a user from harmful radiation and to include a digital camera or cameras (150, 160) to provide dual-spectrum (i.e., both visible spectrum and infrared spectrum) real-time digital video image frames. The welding headgear (110) is also configured with an optical display assembly for displaying real-time digital video image frames to the user while wearing the headgear (110) during an arc welding process. Image processing is performed on the visible and infrared spectrum video image frames to generate dual-spectrum video image frames providing an integrated and optimized view of both the visible and thermal characteristics of the arc welding process which can be viewed by the user on the optical display assembly in real time.

Description

technical field [0001] Certain embodiments relate to visualization of arc welding features during an arc welding process. More specifically, certain embodiments relate to systems, methods, and apparatus (eg, welding helmets) that provide bispectral, real-time visualization, enhanced user-discrimination between arc welding features during an arc welding process. Background technique [0002] During the arc welding process, various forms of radiation are emitted, including light in the visible, infrared, and ultraviolet spectra. The emitted radiation can be of high intensity and can be hazardous to the user's eyes and / or skin if the user is not properly protected. Traditionally, users wear conventional welding helmets having windows with one or more protective lenses to reduce radiation intensity to safe levels. However, such protective lenses, while providing adequate protection for the user, also reduce the amount of light passing through the lens and do not allow the user...
