In general, welding is a method of joining metal joints to heat, and is widely used in various industrial fields, such as structural joining of steel frame construction and piping joining.

There are many types of welding such as welding, pressure welding, brazing, etc. In the welding of double welding, welding is performed by welding a welding rod with a gas torch or an arc discharge to bond different metal members.

Further, the gas torch used for welding may be used for cutting a metal member or the like.

As described above, welding or cutting by the gas torch is usually performed in an open space, and welding by-products such as welding flame and slag generated in the welding or cutting process are scattered to the outside as they are.

Such welding sparks and scattering of welding byproducts are always exposed to the risk of explosion, fire and the like in the course of using gases such as acetylene and propane, which are highly flammable, and may be ignited when they are transferred to surrounding materials.

In addition, welding sparks or welding byproducts are spattered to the worker, often resulting in burns.

Therefore, safety of the welding or cutting process has been demanded, and it has been necessary to develop a flame collecting apparatus that enables safe operation, and techniques such as the following door hurdles have been proposed.

However, the conventional techniques have a disadvantage in that they are difficult to be installed (fixed) for use in a worksite, and therefore, there are many limitations in use. That is, because of the limitation of the fixed form, it can be used only under extremely limited conditions, so that it can not be applied to various working environments and can not be used.
