Description
Technical field
The invention belongs to welding fusing protective device technical field, especially a kind of local air protection cage during fusion welding titanium alloy.
Background technology
Along with titanium alloy is increasingly extensive in the application of every profession and trade, a large amount of titanium alloys need weld, and the melting welding method of the normal welding titanium alloy that adopts is tungsten argon arc TIG weldering, consumable electrode argon arc MIG weldering, plasma welding, electron-bombardment welding etc. at present.
Because the chemism of titanium alloy is big, not only in molten state, even under the high-temperature solid more than 400 ℃, also very easily by pollutions such as air, moisture, grease, oxide-films, absorb impurity such as oxygen, nitrogen, hydrogen, carbon, the plasticity of welding point and toughness are significantly reduced, and easily cause pore.Therefore when welding must to molten bath, weld seam and temperature surpass 400 ℃ heat affected area all will be in addition properly inert gas shielding prevent burning.
Be under vacuum environment, to weld except electron-bombardment welding in titanium alloy T IG weldering, MIG weldering, plasma welding, these welding methods of electron-bombardment welding; do not need to carry out outside the local welding gas shield; other welding methods all are to weld under atmospheric environment, need carry out the local welding gas shield.
Also generally adopt both at home and abroad to add the local gas protection drag the mode of cover to carry out welding protection behind titanium alloy T IG weldering, MIG weldering, plasma welding welding gun, the deficiency that the normal at present local gas protection of adopting drags cover to exist mainly shows:
1, gas path design is unreasonable, makes the distribution of gas that arrives protected metal inhomogeneous, does not have the effect of even protection, and the welding point after causing welding easily turns blue;
2, drag long-time use of cover to be subjected to generating heat seriously after the heat radiation, easily will drag the cover scaling loss sometimes, influence the gas shield effect.
Therefore each unit that is engaged in the titanium alloy molten solder is all trying to explore the novel protected cover that drags, and reaches weld seam postwelding silvery white.
Summary of the invention
For addressing the above problem; the present invention has designed a kind of local air protection cage during fusion welding titanium alloy, and this protection drags cover that the titanium alloy welding joint rear surface is silvery white in color, and welding quality is good; weld seam has good surface and internal soundness, and joint mechanical property meets the demands.
For achieving the above object, the present invention adopts following technical scheme:
Described local air protection cage during fusion welding titanium alloy, its protection drag cover by water inlet pipe, air inlet pipe, outlet pipe, waterway, copper mesh, the plate of giving vent to anger, shirt rim, drag the cover form, wherein drag cover to be cuboid, around dragging the cover upper surface, waterway is set, waterway is connected with water inlet pipe and outlet pipe, and its four limits, lower edge are provided with the shirt rim of flexible exotic material; Drag the cover top that air inlet pipe is installed, air inlet pipe is the T type, and an end is opened aperture, not perforate of the other end; Evenly filling up copper mesh in the middle of the air inlet pipe and the plate of giving vent to anger, the twist drill of giving vent to anger has aperture.
Because adopt aforesaid technical scheme, the present invention has following superiority:
Adopt of the present invention dragging to cover on welding titanium alloy welding point rear surface and be silvery white in color, welding quality is good, and weld seam has good surface and internal soundness, and the butt weld x-ray inspection reaches JB4730 I level, surface seepage reaches JB4730 I level, and joint mechanical property meets the demands.

The specific embodiment
Local air protection cage during fusion welding titanium alloy of the present invention, its protection drag cover by water inlet pipe (1), air inlet pipe (2), outlet pipe (3), waterway (4), copper mesh (5), the plate of giving vent to anger (6), shirt rim (7), drag cover (8) to form, wherein drag cover (8) to be cuboid, around dragging cover (8) upper surface, waterway (4) is set, waterway (4) is connected with water inlet pipe (1) and outlet pipe (3), its four limits, lower edge are provided with the shirt rim (7) of flexible exotic material, drag cover (8) top that air inlet pipe (2) is installed; Air inlet pipe (2) is the T type, and an end is opened aperture, not perforate of the other end; Evenly pad is gone up copper mesh (5) in the middle of air inlet pipe (2) and the plate of giving vent to anger (6), and the plate of giving vent to anger (6) is drilled with aperture.
Each component function is as follows:
1, dragging cover (8) main body top to add waterway (4) and tap into water pipe (1) and outlet pipe (3) in the above, makes protection drag cover (8) to remain water flowing, the state of cooling in use, avoided dragging the scaling loss of cover (8), thereby obtained the excellent protection effect.
2, open aperture on the air inlet pipe (2), and the aperture direction upwards, this just makes to enter and dispels downwards after the gas that drags cover (8) evenly reflexes to the main body top.
3, fill up upward copper mesh (5) uniformly in air inlet pipe (2) and the plate of giving vent to anger (6), make and dragging the distribution of cover (8) gas inside more even.
4, give vent to anger plate (6) for boring the copper coin of aperture, this design is guaranteed more from dragging the uniformity of cover (8) blow gas.
5, install shirt rim (7) additional, material is flexible exotic material, and this is convenient to the soft readjustment in the welding process, protective gas is wrapped in certain zone does not disperse, and guarantees the welding protection effect.
