Description

용접마스크 {WELDING MASK}Welding mask {WELDING MASK}

본 발명은 용접마스크에 관한 것으로, 특히, 예를 들어, TIG 아크용접과 같은 특수용접에 사용되는 자동용접기의 작업을 수행하는 작업자가 착용하여 투시창을 통해 자동용접캐리지에 의한 용접이 이루어지는 용접부위와 자동용접기의 조종을 위하여 작업자가 목에 걸고 조종하는 위한 리모트 펜던트와 같은 펜던트조종기를 편안한 자세에서 투시할 수 있는 용접마스크에 관한 것이다.The present invention relates to a welding mask, and in particular, a welding part where welding by an automatic welding carriage is performed through a viewing window and automatically worn by an operator who performs the work of an automatic welding machine used for special welding such as TIG arc welding. It relates to a welding mask capable of seeing a pendant manipulator, such as a remote pendant for controlling a welding machine by hanging it from the neck of an operator in a comfortable position.

통상적으로 용접을 수행할 때 용접부위에서 발생하는 고광도의 광선으로부터 작업자의 눈을 보호하고 용접시 발생하는 유독가스의 흡입을 방지하기 위하여 작업자는 용접마스크를 착용한다. 종래의 이와 같은 용접마스크는 주로 작업자의 눈을 보호하는데 주안점을 두고 있다. 따라서, 마스크 본체에는 전면에 하나 이상의 보안경이 배치되는 투시창을 갖는 투시부가 구성되어 있다. 이와 같은 투시부는 작업자의 눈의 전면측에 배치되어 용접작업시에 용접부위를 작업자가 눈으로 확인할 수 있도록 하는데 유리하다. 그러나, 종래의 통상적인 용접마스크는 작업자가 전면을 투시할 수 있는 투시창만 구비되어 있어 작업자가 전면이 아닌 다른 방향 또는 부위를 투시하고자 할 때에는 마스크본체를 착용한 안면 전체를 투시하고자 하는 방향으로 움직여야 하는 불편함이 있다. 특히 작업자가 자용용접장치를 이용하여 용접을 수행할 때 용접물에 자동용접캐리지가 이동하면서 용접이 이루어지는 것을 확인함과 동시에 작업자가 목에 걸고 조종하는 리모트 펜던트와 같은 용접조종기를 눈으로 확인하는 것이 필요하다. 이와 같은 경우 작업자가 자신이 착용하고 있는 용접마스크의 전면 투시창만을 이용하여 용접물의 용접부위와 용접조종기를 투시하는데 불편함이 크다. 작업자가 머리를 크게 움직이지 않고 용접물의 용접부위와 용접조종기를 투시하는 것이 바람직할 것이다. 그러나, 종래의 용접마스크에서는 이러한 작업상의 이점을 기대할 수 없는 결점이 있다.In general, when welding is performed, workers wear welding masks to protect the eyes of workers from high-intensity rays generated at the welding site and to prevent inhalation of toxic gases generated during welding. Conventional welding masks such as this are mainly focused on protecting the eyes of workers. Accordingly, the mask body is configured with a see-through unit having a see-through window on which one or more safety glasses are disposed. Such a see-through part is disposed on the front side of the operator's eyes, and is advantageous for allowing the operator to visually check the welding area during welding. However, conventional welding masks are equipped with only a viewing window through which the operator can see through the front, so when the operator wants to see a different direction or part other than the front, it must be moved in the direction to see the entire face wearing the mask body. There is a discomfort. In particular, when an operator performs welding using a self-welding device, it is necessary to confirm that welding is performed while the automatic welding carriage moves to the weldment, and at the same time, it is necessary to visually check a welding controller such as a remote pendant that the operator hangs on the neck and controls. Do. In this case, it is very inconvenient for the operator to see the welding part of the weldment and the welding controller using only the front viewing window of the welding mask that the worker is wearing. It would be desirable for the operator to see the welded part of the weldment and the welding manipulator without moving the head significantly. However, in the conventional welding mask, there is a drawback that such a working advantage cannot be expected.
