Description
Technical Field
The utility model relates to the technical field of mechanical equipment, especially, relate to a manual tungsten electrode argon arc of titanium board welds with weld surface safety cover.
Background
Titanium has light specific gravity, high specific strength and excellent corrosion resistance, is widely applied to the manufacturing of pressure vessels, and is widely applied to the fields of pharmacy, chemical engineering, ocean engineering and the like. Because the titanium welding seam and the heat affected zone are exposed in the air at the temperature of more than 400 ℃ and are very easy to oxidize, and because the titanium has poor heat conductivity, slow cooling speed and long welding high-temperature retention time, the titanium pressure container needs to be well protected by the welding seam and the heat affected zone during welding, so that the oxidation is prevented, and the service life of the product is influenced. The titanium welding generally adopts argon tungsten-arc welding, when manual argon tungsten-arc welding is adopted for welding, and only gas carried by a manual argon tungsten-arc welding gun is used for protection, the surface of a welding seam is still oxidized due to the limitation of a protection area, so that the phenomenon of bluing and graying is caused, and the protection effect does not meet the requirement. After the weld joint and the heat affected zone are oxidized, the plastic toughness of the welded joint is sharply reduced, the corrosion resistance is also deteriorated, and the quality of the equipment cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a welding seam surface protective cover for titanium plate manual tungsten electrode argon arc welding, which comprises a copper protective shell, a copper wire mesh, a copper porous flow distribution plate, a copper air guide tube and a fixed plate, wherein the copper protective shell is respectively welded with the copper porous flow distribution plate and the copper wire mesh into a whole; the copper protective shell is provided with a hole on the top plate and communicated with the copper gas guide pipe; the fixing plate is welded on the copper protective shell at an angle of 45 degrees in an inclined mode, the fixing plate is connected with the clamping ring through a screw rod and a nut, and the clamping ring is fastened through a fastening screw.
The arc diameter of the front part of the copper protective shell is the same as the diameter of the welding gun porcelain sleeve.
The copper wire mesh is positioned below the copper porous flow distribution plate.
Compared with the prior art, the utility model has the following advantage: the structure is simple and the manufacture is easy; the protection effect is good, and the protection gas is saved; the welding gun is light and easy to operate, the protective cover moves along with the welding gun, welding operation can be achieved by a single person, and working efficiency is improved.

Detailed Description
The welding seam surface protection cover for the titanium plate manual argon tungsten-arc welding shown in fig. 1, fig. 2, fig. 3 and fig. 4 comprises a copper protection shell 1, a copper wire mesh 2, a copper porous flow distribution plate 3, a copper air duct 4 and a fixing plate 8, wherein the copper protection shell 1 is welded with the copper porous flow distribution plate 3 and the copper wire mesh 2 into a whole respectively; a hole is formed in the top plate of the copper protective shell 1 and is communicated with the copper gas guide pipe 4; a fixing plate 8 is welded on a copper protective shell 1 at an inclined angle of 45 degrees, the fixing plate 8 is connected with a clamping ring 9 through a screw rod 6 and a nut 7, the clamping ring 9 is fastened through a fastening screw 10, and a tungsten electrode argon arc welding gun is inserted into the clamping ring 9 and is fixedly connected with the tungsten electrode argon arc welding gun through the fastening screw 10. The arc diameter of the front part of the copper protective shell 1 is the same as the diameter of a welding gun porcelain sleeve, so that the copper protective shell can be well attached to a welding gun. The copper wire mesh 2 is located below the copper porous flow distribution plate 3, and after gas is introduced, the gas is firstly buffered and uniformly guided by the copper porous flow distribution plate 3 and then uniformly distributed on the surface of a welding seam through the copper wire mesh 2, so that the gas uniformly protects the surface of the welding seam.
During the use, pack argon tungsten arc welder 11 into in the clamping ring 9, adjust argon arc welder 11's the extension length to guarantee that argon arc welder 11 and copper protective housing 1 laminating are inseparable, will press from both sides clamping ring 9 and connect fixedly in argon tungsten arc welder 11 through fastening screw 10. When the titanium plate is welded, the vent pipe 5 is connected with the copper gas guide pipe 4, argon gas is introduced, the argon gas can be uniformly dispersed on the surface of a welding seam, the protection effect on the welding seam is achieved, the protection cover and the argon arc welding gun 11 are fixed together in the using process and move along with the movement of the welding gun by an operator, and the protection on the welding seam metal in the welding process is well achieved.
The above is the preferred embodiment of the present invention, and the technical personnel in the field of the present invention can also change and modify the above embodiment, therefore, the present invention is not limited to the above specific embodiment, and any obvious improvement, replacement or modification made by the technical personnel in the field on the basis of the present invention all belong to the protection scope of the present invention.
