The utility model discloses a welding protection cover, which comprises a tow cover shell (1), an argon gas inlet pipe (2), an argon gas distribution pipe (3) and a filter screen (4). Argon gas inlet pipe (2) is welded at the center, and argon gas distribution pipe (3) is welded at the end of argon gas inlet pipe (2). ) above the air outlet (6), and the filter screen (4) is welded to the bottom of the drag cover shell to form a protective cover as a whole. The utility model has the advantages of simple structure, low cost and convenient operation, avoids the problem of oxidation in the welding high-temperature zone, and improves the welding quality.
Description
Technical field
The utility model relates to protective cover, is specifically related to a kind of welding protection cover.
Background technology
As everyone knows, in welding process, gaseous impurity pollutes and causes that easily welding point embrittlement, reason are that its absorbed nitrogen of rising along with temperature, the ability of oxygen obviously rise thereupon.The weld seam oxygen content rises, and the tensile strength and the hardness of weld seam obviously rise, and plastic property of weld bead obviously descends, and weld seam becomes fragile because of the pollution of oxygen; Nitrogen increases in the solubility of the high temperature fluent metal dividing potential drop with oxygen, the influence of nitrogen butt welded seam intensity, hardness, plasticity is more more remarkable than oxygen, the pollution embrittling effect that is to say nitrogen is more stronger than oxygen, the influence of nitrogen butt welded seam mainly is the influence of impact toughness, nitrogen content increases, and the impact flexibility of weld seam is significantly reduced; In order to guarantee the quality of welding point; prevent that gaseous impurity from polluting; when carrying out industrial welding; often allow welding gun form the gas shield layer; and the formed gas shield layer of existing welding gun can only protect welding pool not to be subjected to air pollution, to solidifying weld seam and the then unprotect effect of heat affected area thereof that is in the condition of high temperature.
Summary of the invention
The purpose of this utility model is: a kind of welding protection cover is provided, adopts this protective cover to avoid the molten bath of high temperature melting and droplet metal to be polluted by gaseous impurity, improve welding quality.
Technical solution of the present utility model is: this protective cover comprises and drags cover shell, argon inlet pipe, argon gas distributor pipe and screen pack; dragging the center welding argon inlet pipe of cover shell; the end welding argon gas distributor pipe of argon inlet pipe; the argon gas distributor pipe is positioned at and drags the cover shell; the top distribution venthole of argon gas distributor pipe; drag the bottom welding screen pack of cover shell, whole formation protective cover.
Wherein, dragging cover to be welded to connect part on the shell.
During installation, protective cover is installed on the welding gun through connector; During use; argon gas is entered in the argon gas distributor pipe by argon inlet pipe; venthole ejection through argon gas distributor pipe top is evenly distributed and is cushioned; when air-flow process screen pack; obtain sub-distribution again; improve the flow regime of argon gas, argon gas is extruded all air, makes directly solidification forming under the protection of argon gas stratosphere of molten pool metal.
The utility model is simple in structure, and is with low cost, easy to operate, avoids improving welding quality in welding high-temperature region problem of oxidation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 drags the cover shell, 2 argon inlet pipe, 3 argon gas distributor pipes, 4 screen packs, 5 connectors, 6 ventholes, 7 welding guns.
The specific embodiment
As shown in Figure 1; this protective cover comprises and drags cover shell 1, argon inlet pipe 2, argon gas distributor pipe 3 and screen pack 4; dragging the center welding argon inlet pipe 2 of cover shell 1; the end welding argon gas distributor pipe 3 of argon inlet pipe 2; argon gas distributor pipe 3 is positioned at and drags cover shell 1; the top distribution venthole 6 of argon gas distributor pipe 3 drags the bottom of the outer shell of cover to weld screen pack 4, whole formation protective cover.
Wherein, dragging cover to be welded to connect part 5 on the shell 1.
During installation, protective cover is installed on the welding gun 7 through connector 5; During use; argon gas is entered in the argon gas distributor pipe 3 by the argon inlet pipe pole; venthole 6 ejections through argon gas distributor pipe 3 tops are evenly distributed and are cushioned; when air-flow process screen pack 4; obtain sub-distribution again; improve the argon gas flow regime, argon gas is extruded all air, makes directly solidification forming under the protection of argon gas stratosphere of molten pool metal.
Claims (2)
1. welding protection cover; it is characterized in that: this protective cover comprises and drags cover shell (1), argon inlet pipe (2), argon gas distributor pipe (3) and screen pack (4); dragging the center welding argon inlet pipe (2) of cover shell (1); the end welding argon gas distributor pipe (3) of argon inlet pipe (2); argon gas distributor pipe (3) is positioned at and drags cover shell (1); the top distribution venthole (6) of argon gas distributor pipe (3); drag the bottom welding screen pack (4) of the outer shell of cover, whole formation protective cover.
