Abstract
The utility model discloses a bonded ceramic welding lining pad, which comprises a ceramic lining pad body and fixed glue strips, wherein the ceramic lining pad body is provided with grooves at the upper surface, the fixed glue strips are attached on the bottom part of the ceramic lining pad body, metal strips in a shape matched with that of the grooves are arranged in the grooves, the height of the metal strips is equal to or smaller than the depth of the grooves, the base layer of the fixed glue strips is a thin metal layer, a protective layer is covered on the upper surface of the glue layer coated on the base layer, and vent holes are respectively arranged on the fixed glue strips arranged at both sides of the ceramic lining pad body. The utility model has the advantages that the metal strips are arranged in the grooves arranged at the upper surface of the ceramic lining pad body, and the utility model ensures that the electric arc extinguishment can not occur during the welding and the phenomenon of ceramic lining pad falling through being ejected by generated welding wires can not be generated during semi-automatic or automatic welding because of the electricity conductivity of the metal strips. Because the metal strips become a part of welding seams after the welding is completed, the taking-out problem does not exist, the structure is very simple, and in addition, the processing cost is very low.
Description
Technical field
Used a kind of auxiliary material when the utility model relates to metal solder especially relate to a kind of auxiliary adhesive type ceramic welding backing that welds in the metal works groove to be welded back side that places.
Background technology
When metal works is welded, if adopt single-sided welding technology, only weld in the welding base metal front, the high-temperature electric arc fusing that welding wire and mother metal are produced during weld job can form high temperature solution, welding backing promptly be the high temperature solution that is used to prevent from when weld job, to form by a kind of gasket material under the slit flow of soldered material, and the ceramic product with good resistance to elevated temperatures can be described as the material that is suitable for being used for doing liner most.Present ceramic welding backing is made up of ceramic substrate and fixture (as the adhesive sticker aluminium foil).Place ceramic substrate before the welding earlier at the metal works groove to be welded back side, it is fixing to utilize the adhesive sticker aluminium foil that it is pasted, and begins welding in the metal works front, once can finish the welding job of whole welding line.But because ceramic substrate is to stick on the metal works bevel for welding back side, it is non-conductive, and excessive velocities during welding is prone to the arc extinction phenomenon, causes the welding process instability; When adopting semi-automatic and automatic weldering, continue proal welding wire after the blow-out and can push up on the ceramic substrate, make ceramic substrate and back of work generation space even come off, directly influence welding quality.
In order to address this problem, common way is to install gasket support bracket additional in back of work.China's utility model patent (patent No.: 200920154923.7) disclose and a kind ofly install magnetic welding ceramics gasket support bracket additional in back of work, magnetic bracket is adsorbed on the steel plate of back of weld, elastic mechanism in the support compresses ceramic substrate, just can stop ceramic substrate and back of work generation space effectively or comes off.But for the metal structure welding of difformity and size, should conveniently install additional, be convenient to again take out, be to be difficult to realize; When welding nonmagnetic material in addition, magnetic welding ceramics gasket support bracket will lose efficacy.
The utility model content
The purpose of this utility model is the deficiency that exists at above-mentioned prior art and a kind of adhesive type ceramic welding backing that provides.
For achieving the above object, the utility model can be taked following technical proposals:
Adhesive type ceramic welding backing described in the utility model comprises that upper surface has the ceramic substrate body of groove and attached to the fixedly viscose top of described ceramic substrate body bottom, is provided with the bonding jumper that is complementary with its shape in the described groove.
The height of described bonding jumper is equal to or less than the degree of depth of described groove.
The basic unit of described fixedly viscose top is a thin metal layer, and the adhesive-layer upper surface that is coated in the described basic unit is coated with overcoat.
Offer air-vent respectively on the fixedly viscose top of described ceramic substrate body both sides.
Advantage of the present utility model is to be provided with bonding jumper in the ceramic substrate body upper surface groove, because the electric conductivity of bonding jumper, thereby arc extinction can not occur when guaranteeing welding, and is semi-automatic or also can not produce the phenomenon of welding wire roof fall ceramic substrate when welding automatically.Because bonding jumper has become the part of weld seam after welding is finished, do not have the taking-up problem, structure is very simple and processing cost is very low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, adhesive type ceramic welding backing described in the utility model, comprise that one group of upper surface has the ceramic substrate body 1 of groove and attached to the fixedly viscose top 2 of this group ceramic substrate body 1 bottom, is provided with the bonding jumper 3 that is complementary with its shape in the described groove.Before carrying out welding job, welding backing is placed at the metal works groove to be welded back side, make bonding jumper be fitted in the groove to be welded place of metal works, utilization fixedly viscose top 2 is pasted fixing getting final product with it.
Pyrosol can not ooze out from the edge of ceramic substrate during for the assurance welding, and the height of described bonding jumper 3 is equal to or less than the degree of depth of described groove.
Firm being bonded on the metal works of ceramic substrate body 1 energy during for the assurance welding, the basic unit 4 of described fixedly viscose top 2 is thin metal layer (as aluminium foil or a sheet iron); For preventing the contaminated inefficacy of adhesive-layer, the adhesive-layer upper surface that is coated in the described basic unit 4 is coated with overcoat 5.
Offer air-vent 6 respectively on the fixedly viscose top 2 of described ceramic substrate body 1 both sides, the flue gas when air during stickup and welding can be discharged by air-vent 6.
