Description
Technical field
The present invention relates to a kind of welding tooling, specifically a kind of titanium steel soldering test gas shield tooling.
Background technique
The welding of metal has melting welding, pressure welding and soldering three categories by the characteristics of its technical process points
During melting welding, if atmosphere is directly contacted with the molten bath of high temperature, the oxygen in atmosphere will gold oxide
Belong to and various alloying elements.Nitrogen, water vapour in atmosphere etc. enter molten bath, can also be formed in weld seam in subsequent cooling process
The defects of stomata, slag inclusion, crackle, deteriorates the quality and performance of weld seam.
In order to improve welding quality, various guard methods are constantly had investigated.For example, gas shielded arc welding is exactly to use
The gas-insulated atmosphere such as argon, carbon dioxide, to protect the electric arc and molten bath rate when welding；For another example when welded steel, in welding rod medicine
The titanium-iron powder big to oxygen affinity is added in skin and carries out deoxidation, so that it may protect in welding rod beneficial element manganese, silicon etc. from oxidation
And enter molten bath, quality weld is obtained after cooling.
The common feature of various press welding methods is to apply pressure in the welding process, without adding packing material.Most pressure weldings
Method, such as diffusion welding (DW), ratio-frequency welding, cold welding is all without fusion process, because without as melting welding, useful alloy element
The problem of scaling loss and harmful element intrusion weld seam, to simplify welding process, also improve Welding Safety sanitary condition.Simultaneously
Since heating temperature is lower than melting welding, heating time is short, thus heat affected area is small.Many is difficult to the material welded with fusion welding, past
Toward the high-quality connector that can be welded into pressure welding with base material equality strength.
It is formed when welding, the seam for connecting two connected bodies is known as weld seam.The two sides of weld seam will receive in welding
Heat effect is welded, and tissue and performance change has occurred, this region is called heat affected area.Because workpiece material welds when welding
Connect the difference of material, welding current etc..Deteriorating weldability, this just needs to adjust the condition of welding, butt-welding fitting interface before welding
Preheating, weldering when heat preservation and post weld heat treatment, the welding quality of weldment can be improved.
In addition, welding is the rapid heating and cooling procedure of a part, welding section is due to by surrounding workpiece body
It restrains and is unable to free wxpansion and contraction, just generate welding stress and distortion in weldment after cooling.Staple product postwelding all needs
Welding stress is eliminated, welding deformation is corrected.
Modern welding technology can weld the weld seam that without inside and outside defect, mechanical performance is equal to even higher than connected body.
It is soldered body and is known as welding point in the mutual alignment in space, the intensity of joint is also several with it in addition to being influenced by weldquality
What shape, size, stress condition and operating condition etc. is related.The citation form of connector has docking, overlap joint, T-shaped to connect (positive handover)
With corner connection etc..
Underwater sonar protective shell material is titanium alloy, and ship hull plate material is DH36 steel plate.In view of factory is without correlation
The experience of titanium and steel welding, need to carry out relevant test, to verify whether to meet production requirement；Under high temperature titanium be easy to absorb hydrogen,
Oxygen, nitrogen if welding section can make weld contamination and embrittlement occurs containing these gases, or even generate stomata, it is therefore necessary to use inertia
Gas shielded welding region.
It does experiment (actual production can not carry out under vacuum conditions), can only make since factory can not provide vacuum environment
Make gas shield tooling to simulate vacuum environment, it is contemplated that weld seam is tow sides, therefore need to make positive gas shield and back
Two kinds of toolings of face gas shield.
Summary of the invention
The purpose of the present invention is to provide a kind of titanium steel soldering test gas shield toolings, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the invention provides the following technical scheme:

It surrounds and drags cover box, cover box bottom opening is dragged to be arranged.
As a further solution of the present invention: the intensive orifice plate distance drags cover bottom surface 5mm to install.
As further scheme of the invention: described that cover side and the back side is dragged to wrap up the heat-resisting gasket of " apron " shape, energy
Preferably isolation air, allows air not penetrate into the problems such as commissure makes weld contamination and embrittlement occurs.
Compared with prior art, the beneficial effects of the present invention are: ventilation box uses the form of One In and Two Out, and wherein
One outlet adds air outlet valve, and such benefit is, as upper surface open area is gradually filled up by weld seam, so that air pressure in box
It is continuously increased, by adjusting air outlet valve, so that gas distribution, preventing air pressure excessively high will push up on the weld seam at the sinking test plate (panel) back side, make
It is bad at forming, while welded seam area can be placed in argon gas region by the rectangular aperture of tooling upper surface completely, play the back side
The purpose of protection；
Drag cover using one into the form having more, intensive well plate format is taken in gas outlet, and air inlet adds baffle shunt gas,
Outlet gas is uniformly flowed out, and non-central place's air pressure is big, the small situation of other region air pressures, at the same intensive orifice plate away from
It is mounted on from bottom surface 5mm and cover bottom is dragged to form argon space, weld seam upper surface is constantly in argon gas protection；
Cover side and the back side are dragged " apron " shape package is made using heat-resisting gasket, can preferably completely cut off air, allow air
The problems such as commissure makes weld contamination and embrittlement occurs is not penetrated into；
By the inspection of test piece for welding, which assumes responsibility for the work of top and bottom weld seam protection, significant effect, solution well
