Abstract
The invention discloses a manual welding seam protection device which comprises a protective cover jointed with the outer periphery wall of a steel pipe; the jointing side of the protective cover with the steel pipe is opened; a protection cavity is arranged in the protective cover; the protective cover is provided with an air inlet port communicated with the protection cavity; and a mounting and placing part for mounting and placing a welding gun is arranged on the protective cover. The manual welding seam protection device has the beneficial effect that the situation that a welding seam and a heat-affected zone of the welding seam are blackened due to oxidation and are cracked can be avoided, so that the quality of the welding seam is improved, and the welding qualified rate is improved.
Description
Technical field
The present invention relates to protective device, be meant a kind of manual weld seam protection device that is used for the steel pipe welding especially.
Background technology
Commonly used often at welding titanium, pick alloy pipeline at present to argon arc welding; In the welding gun running, weld seam and heat affected area thereof temperature after welding is higher, owing to there is not protective device; In the cooling procedure easily by oxygen institute oxidation in the air; Weld seam and heat affected area color blackening thereof, and be easy to generate crackle, cause solder yield lower.
Summary of the invention
Technical problem to be solved by this invention is: a kind of manual weld seam protection device is provided, and this protective device can be avoided welding position and oxidized blackening thereof on every side and crack, and improves the quality of weld seam, improves solder yield.
For solving the problems of the technologies described above; Technical scheme of the present invention is: manual weld seam protection device; Comprise the protective cover that is used for the applying of steel pipe periphery wall, the applying side opening of said protective cover and steel pipe is provided with the protection chamber in the said protective cover; Said protective cover is provided with and the intake interface of protecting the chamber to be communicated with, and said protective cover is provided with the parts of laying that are used to lay welding gun.
As a kind of preferred scheme, said protection is equipped with turbulent device in the chamber.
As a kind of preferred scheme, said turbulent device comprises the wire wire netting outer with being coated on wire that is filled in the protection chamber.
As a kind of preferred scheme, the said parts of laying comprise a mounting groove.
As a kind of preferred scheme, the said parts of laying comprise an installation sleeve.
As a kind of preferred scheme, the mounting means of said installation sleeve and said protective cover is for being fixedly connected.
As a kind of preferred scheme, the mounting means of said installation sleeve and protective cover is hinged, and said installation sleeve is installed on the protective cover through hinge, and said installation sleeve can rotate around hinge.
After having adopted technique scheme; Effect of the present invention is: manual weld seam protection device; Comprise the protective cover that is used for the applying of steel pipe periphery wall, the applying side opening of said protective cover and steel pipe is provided with the protection chamber in the said protective cover; Said protective cover is provided with and the intake interface of protecting the chamber to be communicated with, and said protective cover is provided with the parts of laying that are used to lay welding gun.Welding gun is placed on lays in the parts, in the protection chamber, feed inert gas from intake interface, a people hands welding gun; One people rotates protective cover, and two people cooperate each other, and welding gun is along treating that welding bead moves; Inert gas butt welding is taken in the protection chamber weld seam and heat affected area thereof are protected; Avoid in weld seam and the heat affected area cooling procedure thereof because of the blackening of oxidation color and crack, improve the quality of weld seam, improve the qualification rate of welding.
Again owing in the said protection chamber turbulent device is installed; The turbulent flow device can form turbulent flow from the inert protective gas buffering that the high speed that intake interface feeds is concentrated; Both improve the protection effect of protective gas butt welded seam and heat affected area thereof, practiced thrift the consumption of inert gas again.
Because the mounting means of said installation sleeve and protective cover is flexible connection, and said installation sleeve is installed on the protective cover through hinge, and said installation sleeve can rotate around hinge, therefore, welding gun is installed in can be according to the angle of welding needs adjustment welding gun in the installation sleeve again.

Below in conjunction with accompanying drawing and embodiment the manual weld seam protection device of the present invention is further specified.
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the cutaway view of the A-A of the embodiment of the invention;
1. protective cover; 2. installation sleeve; 3. intake interface; 4. wire; 5. wire netting.
The specific embodiment
Through specific embodiment the manual weld seam protection device of the present invention is done further to describe in detail below.
Like Fig. 1, shown in 2, manual weld seam protection device; Comprise the protective cover 1 that is used for the applying of steel pipe periphery wall; The applying side opening of said protective cover 1 and steel pipe is provided with the protection chamber, in the present embodiment in the said protective cover 1; Said protection is equipped with turbulent device in the chamber, and said turbulent device comprises wire 4 that is filled in the protection chamber and the wire netting 5 that is coated on outside the wire 4.Certainly; The wire 4 that is filled in the protection chamber can also be other similar structures; As can be several wire netting 5 stacked forming, its main purpose is that the gas stream buffering of concentrating is at a high speed formed turbulent flow, with to weld seam and heat affected area better protection after the welding.
Said protective cover 1 is provided with and the intake interface of protecting the chamber to be communicated with 3, and said protective cover 1 is provided with the parts of laying that are used to lay welding gun.In the present embodiment, the said parts of laying comprise an installation sleeve 2, and the mounting means of said installation sleeve 2 and said protective cover 1 is for being fixedly connected.Certainly, also can directly on said protective cover 1, be provided with the mounting groove that is used to lay welding gun, welding gun leans against in the mounting groove can guarantee weld seam.
During welding welding gun is placed in the installation sleeve 2, in the protection chamber, feeds inert gas from intake interface 3, a people hands welding gun; One people rotates protective cover 1, two people and cooperates each other, and welding gun moves welding along welding bead; After inert gas produced turbulent flows through wire 4, the weld seam and the heat affected area thereof that see through after 5 pairs of welding of wire netting were protected, and avoided in weld seam and the heat affected area cooling procedure thereof because of the blackening of oxidation color and cracked; Improve the qualification rate of welding, improve the quality of weld seam.
In addition, said installation sleeve 2 can also be movably installed on the protective cover 1, and said installation sleeve 2 is installed on the protective cover 1 through hinge, and said installation sleeve 2 can rotate around hinge, can be according to the angle of welding needs adjustment welding gun.
