Description

빛 개폐창이 형성된 용접헬멧{Welding helmet}Welding helmet with light opening and closing window {Welding helmet}

본 발명은 빛 개폐창이 형성된 용접헬멧에 관한 것으로서, 더욱 상세하게는 용접헬멧(용접마스크 등을 포함) 측면에 외부 빛을 차폐할 수 있도록 빛 개폐도어를 형성하여 작업자가 필요시에 외부 빛의 개방과 차단이 가능한 용접헬멧에 관한 것이다.
The present invention relates to a welding helmet in which a light opening and closing window is formed, and more particularly, a light opening and closing door is formed to shield external light on the side of the welding helmet (including a welding mask, etc.) so that an operator opens the external light when necessary. The present invention relates to a welding helmet that can be blocked.

일반적으로, 아아크 용접은 금속의 가융성을 이용하여 국부적으로 가열하고 용해하여 두 금속의 접합하는 것으로서 용접작업시 발생되는 고열과 빛 및 가스로 부터 작업자를 보호하기 위한 보호장구의 하나로 용접헬멧을 착용한다.In general, arc welding utilizes the fusible properties of metals to locally heat and dissolve to join two metals, and wears a welding helmet as one of the protective devices for protecting workers from high heat, light and gas generated during welding. do.

특히, 용접헬멧은 용접이나 절단 등의 작업을 수행할 경우 눈과 안면을 보호하기 위하여 사용된다. 그리고 이러한 용접헬멧에는 용접이나 절단 등의 작업을 수행할 경우 발생되는 강렬한 유해광으로부터 사용자의 눈을 보호하기 위한 눈부심방In particular, welding helmets are used to protect the eyes and face when performing welding or cutting. In addition, the welding helmet has a glare to protect the user's eyes from the intense harmful light generated when welding or cutting is performed.

지장치(이하카트리지(cartridge)"라 함)가 고정 장착된다. 이와 같은 카트리지는 통상780nm(ib)이상 365nm(uv)미만의 광선을 차단시키고 가시광선의 투과량을 제어하여 눈부심 없이 용접위치를 눈으로 확인하면서 작업을 수행할 수 있도록 하였다.The device (hereinafter referred to as a "cartridge") is fixedly mounted. Such a cartridge normally blocks 780 nm (ib) or more and less than 365 nm (uv) light and controls the amount of visible light transmitted to the eye, thereby preventing the glare of the welding position. It was possible to perform the operation while checking.
