Abstract
The utility model discloses a welding pad, which is characterized in that the pad includes a metal support layer of the groove, and a flexible graphite belt is adhered in the groove. The utility model adopts graphite belt made of flexible graphite to paste in the metal support layer groove to constitute a welding backing, which has simple structure, low cost, multiple use of the flexible graphite belt tape, and easy replacement. The welding pad is very suitable for consumable electrode and non-consumable electrode aluminum alloy single face welding and double face shaping, and has spread value in the field of aluminum alloy automatic welding.
Description
Technical field
The utility model relates to a kind of welding backing that is used for the weldering of aluminium alloy single face.
Technical background
(simultaneously weld at aluminium alloy single face weldering double-faced forming at present at metal to be welded, the back side also is formed with the weld seam of certain reinforcement and width) technology in, usually adopt the free forming method, promptly when single face welding and double face shaping, the metal to be welded back side does not add to set off and stops liquid metal to flow, and only relies on welding procedure to guarantee that the back side forms weld seam; This forming method difficulty is big, the technological parameter harshness.Also can stop liquid metal to flow, to realize the even moulding of sealing run in metal to be welded back side lining holder (liner).Gasket material has ceramic, asbestos, glass fibre, metal gasket etc.Existing liner cost height or result of use are undesirable.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, with low cost, can repeatedly use, change and be easy to soft graphite and strengthen the composite welding liner.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of welding backing is characterized in that, comprises the metal supporting layer that is provided with groove, posts flexible graphite belt in the groove.
In the such scheme, described flexible graphite belt is provided with pressure-sensitive adhesive layer with the one side that the metal supporting layer groove pastes mutually.Described flexible graphite belt is made by squama graphite.
Soft graphite claims expanded graphite again, and it is a raw material with squama graphite, handles generating intercalation compound through chemical industry, has softness, and is high temperature resistant, can process sheet characteristics, is widely used in field of sealing technology.The graphite tape that the utility model adopts soft graphite to make is pasted on the welding backing that constitutes in the metal supporting layer groove and is very suitable for consumable electrode and non-melt pole aluminium alloy single face weldering double-faced forming, promotional value is arranged aspect the weldering automatically at aluminium alloy.Soft graphite of the present utility model strengthens the composite welding liner and has following advantage:
1, radiationless pollution-free.
2, the high temperature high temperature resistant, that the graphite tape ability is 1650 ℃.At high temperature, high pressure or radiation condition be work down, do not decompose, and distortion or aging, chemical property is stable.
3, with low cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a cross-section structure of the present utility model.
Fig. 2 is the frock schematic diagram of Fig. 1 liner.
Among the figure: 1, metal supporting layer; 2, pressure-sensitive adhesive layer; 3, flexible graphite belt; 4, screw; 5, leading screw.
The specific embodiment
The flexible graphite belt 3 that as shown in Figure 1 back side is scribbled pressure-sensitive adhesive layer 2 is pasted in the groove of metal supporting layer 1.Flexible graphite belt is made by squama graphite.Pressure-sensitive adhesive layer is made by common adhesive sticker; Effect is to connect metallic support and soft graphite liner.Metal supporting layer 1 is a common iron.
Set off liquid flowable deposite metal at the metal to be welded back side when effect of liner shown in Figure 1 is welding, force liquid metal to form the sealing run of certain altitude.
Fig. 2 is a frock example of Fig. 1 liner, is used for the welding of cylindrical shell butt girth welding seam, with liner coiled one annular, metal supporting layer 3 at ring two ends is respectively welded a screw in it, connect by leading screw, and can adjust loop size among a small circle, with for convenience detach and be adjacent to cylinder inboard wall.
Claims (3)
1, a kind of welding backing is characterized in that, comprises the metal supporting layer that is provided with groove, posts flexible graphite belt in the groove.
2, welding backing according to claim 1 is characterized in that, described flexible graphite belt is provided with pressure-sensitive adhesive layer with the one side that the metal supporting layer groove pastes mutually.
3, welding backing according to claim 1 is characterized in that, described flexible graphite belt is made by squama graphite.
