Abstract
The utility model provides an airflow channel that tungsten utmost point argon arc welds welder nozzle, including the nozzle body, this internally is used for the argon gas that circulates along what axial had a perfect understanding around being formed with at the nozzle the afterbody of nozzle body is formed with the internal thread that is used for connecting welder, airflow channel go up and to be formed with many the air guide grooves to concave yield in the wall of nozzle body along the axial. The air guide groove be in airflow channel on be provided with 2-4. The utility model discloses when using, guard action that can full play protection gas reduces because protection gas forms the turbulent flow and is drawn into too much air among the welding process, reduces molten bath liquid metal owing to absorb too much gas formation gas pocket, increases the stability of electric arc among the welding process, improves welding quality. The utility model discloses simple structure, easy manufacturing, low cost can improve welding quality by a wide margin.
Description
Technical field
The utility model relates to a kind of tungsten electrode argon arc welding gun.Particularly relate to a kind of tungsten electrode argon arc welding gun nozzle improving argon tungsten-arc welding gas shield effect.
Background technology
Argon tungsten-arc welding is the one of gas tungsten arc welding.Because the repeatability of its welding procedure is strong, welding quality stable, the good feature of appearance of weld, has in many essential industry departments and applies more widely.In argon arc welding operating process, argon gas is inert gas, do not decompose under there is high temperature and not with the characteristic of weld metal generation oxidation reaction, the purity welding quality of argon gas has a great impact.In argon gas the impurity content such as oxygen, nitrogen dioxide, hydrogen, moisture content be above standard regulation time, can be that electric arc is unstable, weld properties declines, and weld porosity increases, and is shaped and worsens.The purity of argon gas is the important parameter affecting protected effect.
Argon arc welding nozzle conventional is at present the columnar structured of a kind of interior smooth, is easy to produce turbulent flow when in cylinder, argon flow amount acquires a certain degree, and air is involved in protection zone, reduces protected effect, and cause electric arc unstable, weld seam produces cavitations.Strength deflection can be caused again inadequate if reduce gas flow, also not reach protective effect.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of protection gas that can reduce to occur turbulent flow, forms laminar flow protection gas, strengthen the tungsten electrode argon arc welding gun nozzle of the protected effect of weld zone.
The technical scheme that the utility model adopts is: a kind of tungsten electrode argon arc welding gun nozzle, include nozzle body, the gas channel for the argon gas that circulates through before and after being formed vertically in nozzle body, the afterbody of described nozzle body is formed with the internal thread for connecting welding gun, described gas channel is formed with vertically many air slots recessed in the wall of nozzle body.
Described air slot is provided with 2 ~ 4 on described gas channel.
2 ~ 4 described air slots on described gas channel for being uniformly distributed.
The degree of depth recessed in the wall of nozzle body of described air slot is 1 ~ 2mm
A kind of tungsten electrode argon arc welding gun nozzle of the present utility model; in use; the protective effect of protection gas can be given full play to; reduce in welding process and be involved in too much air because protection gas forms turbulent flow; reduce molten bath liquid metals due to hyperabsorption gas formation pore; increase the stability of electric arc in welding process, improve welding quality.The utility model structure is simple, be easy to manufacture, with low cost, welding quality can be improved significantly.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, a kind of tungsten electrode argon arc welding gun nozzle of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, a kind of tungsten electrode argon arc welding gun nozzle of the present utility model, include nozzle body 1, the outside of nozzle body 1 is cylindrical structure, the gas channel 2 for the argon gas that circulates through before and after being formed vertically in nozzle body 1, the afterbody of described nozzle body 1 is formed with the internal thread for connecting welding gun, described gas channel 2 is formed with vertically many air slots 3 recessed in the wall of nozzle body 1.Due to the effect of air slot 3, protection gas can be reduced and form turbulent flow, and with laminar condition protection weld zone.
As shown in Figure 2, described air slot 3 is provided with 2 ~ 4 on described gas channel 2.2 ~ 4 described air slots 3 on described gas channel 2 for being uniformly distributed.Described air slot 3 is 1 ~ 2mm to the recessed degree of depth in the wall of nozzle body 1.
A kind of tungsten electrode argon arc welding gun nozzle of the present utility model, during use, is first threaded connection with the ceramic nozzle of air slot and welding gun rifle body, thus can gas be protected by air slot to be blown into the welding position that will protect in the process of welding.
In embodiments of the invention, nozzle body 1 external diameter of selection is 15mm, internal diameter 8mm, long 47mm, and air slot 3 is 2mm to the recessed degree of depth in the wall of nozzle body 1.
