Abstract
The utility model discloses a kind of novel arc and drag cover, it relates to drags cover field, it comprises arc and drags cover body, welded pipe fitting lay down location, first air inlet, argon-arc welding gun, gas outlet, second air inlet, even gas outlet, arc drags the middle part of cover body to be provided with welded pipe fitting lay down location, arc drags the top of cover body to be provided with the first air inlet, argon-arc welding gun is provided with in first air inlet, the below of the first air inlet is provided with gas outlet, arc drags the side of cover body to be provided with the second air inlet, the medial surface of welded pipe fitting lay down location is provided with even gas outlet.Its reasonable in design, simple to operate, easy to use, not only can accomplish inside and outside all gas-filled protectives, protective gas evenly and is slowly full of welding region, can also be effective by heat affected area and air exclusion.
Description
technical field:
The utility model relates to a kind of novel arc and drags cover, belongs to and drags cover technical field.
background technology:
The affinity of titanium and oxygen is very large; fine and close oxide-film can be generated in room temperature; at high temperature to oxygen, nitrogen, hydrogen etc., there is great affinity; require in welding process to take good safeguard measure to welding region; guarantee positive and negative, heat affected area more than 350 DEG C of welding pool and temperature and air exclusion; and the existing cover structure that drags designs rationalization not; cannot accomplish that inside and outside homogenous charge is protected; the gas of protection evenly and slowly cannot be full of welding region, can not effectively by heat affected area and air exclusion.
utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of novel arc and drags cover.
A kind of novel arc of the present utility model drags cover, it comprises arc and drags cover body, welded pipe fitting lay down location, the first air inlet, argon-arc welding gun, gas outlet, the second air inlet, evenly gas outlet, arc drags the middle part of cover body to be provided with welded pipe fitting lay down location, arc drags the top of cover body to be provided with the first air inlet, argon-arc welding gun is provided with in first air inlet, the below of the first air inlet is provided with gas outlet, arc drags the side of cover body to be provided with the second air inlet, and the medial surface of welded pipe fitting lay down location is provided with even gas outlet.
The beneficial effects of the utility model: its reasonable in design, simple to operate, easy to use, not only can accomplish inside and outside all gas-filled protectives, protective gas evenly and is slowly full of welding region, can also be effective by heat affected area and air exclusion.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
1-arc drags cover body; The welded pipe fitting lay down location of 2-; 3-first air inlet; 4-argon-arc welding gun; 5-gas outlet; 6-second air inlet; The even gas outlet of 7-.
detailed description of the invention:
As shown in Figure 1, this detailed description of the invention is by the following technical solutions: it comprises arc and drags cover body 1, welded pipe fitting lay down location 2, first air inlet 3, argon-arc welding gun 4, gas outlet 5, second air inlet 6, even gas outlet 7, arc drags the middle part of cover body 1 to be provided with welded pipe fitting lay down location 2, arc drags the top of cover body 1 to be provided with the first air inlet 3, argon-arc welding gun 4 is provided with in first air inlet 3, the below of the first air inlet 3 is provided with gas outlet 5, arc drags the side of cover body 1 to be provided with the second air inlet 6, the medial surface of welded pipe fitting lay down location 2 is provided with even gas outlet 7.
This detailed description of the invention in use, out to protect around argon-arc welding gun 4 from gas outlet 5 be full of inert gas when the first air inlet 3 enters inert gas, ensure no oxygen, hydrogen etc., second air inlet 6 enters inert gas, arc is dragged in cover body 1 and is full of inert gas, arc drags gassy in cover body 1 to be to ensure can evenly to give vent to anger in even gas outlet 7, the gas outlet that can not have is given vent to anger many, some gas outlets are given vent to anger few, ensure to be uniformly distributed inert gas around welded pipe fitting solder joint, thus reach isolation from oxygen, the gases such as hydrogen, if arc drags not circulation in cover body 1, can directly a bit directly go out from certain of even gas outlet 7 after gas may enter from the second air inlet 6, cannot ensure evenly to give vent to anger in all gas outlets of even gas outlet 7 like this, air turbulence near solder joint may be caused like this, be mixed into other gas.
This detailed description of the invention reasonable in design, simple to operate, easy to use, not only can accomplish inside and outside all gas-filled protectives, protective gas evenly and is slowly full of welding region, can also be effective by heat affected area and air exclusion.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
