Description

WELDING PROTECTION GLASS AND METHOD FOR

BACKGROUND
Technical Field of Invention
[001] The embodiments herein generally relate to a protection equipment and particularly relates to a welding protection glass and a process of fabricating the welding protection glass. The embodiments herein more particularly relate to a welding protection glass with variable shades to control a preferred wavelength and amount of light coming during a welding process.
Description of Related Art
[002] A welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that is usually stronger than the base material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized.
[003] In order to achieve an effective welding process, one of the prior arts discloses a protection welding lens assembly for use as the eyepiece of a welding helmet. The lens assembly utilizes a liquid crystal light shutter together with an electrical circuit adapted to change the light shutter from a uniform light-transmitting condition to a uniform, approximately opaque condition of very small light transmission solely in response to light energy emitted by an electric welding arc without the use of any connecting wires. Two light sensing devices are employed, one of which responds to visible light only and the other of which responds to infrared wave energy only. In order to change the light shutter from a light-transmitting to an opaque condition, both the visible and infrared wave energies from the arc must be sensed.
[004] However, the prior art welding equipment a limited to a particular shade leading to utility in specific applications. To change an intrinsic property of the welding equipment, a change in fabrication process is required that leads to massive loss of time and capital.
[005] In the view of foregoing, there is a need for a welding protection glass with a fabrication method for achieving a plurality of shades. Also, there is a need for a welding protection glass with variable light allowance ability.
