Abstract

The utility model provides a welding pad which is formed by connecting a plurality of single pads end to end, wherein the head and the tail of the single pad are respectively a convex circular arc and a concave circular arc; the outlines of the two circular arcs are matched to each other; the bottoms of the plurality of single pads are provided with connection belts which connect and fix the single pads. After the welding pad is bent, the single pads connected end to end are still tightly connected together without clearance formed, which can meet the requirements of welding joints with different line shapes, thus avoiding the requirement of producing a large quantity of pad blocks with different shapes to adapt to different joints, and reducing the production cost.

Description

A kind of welding backing

Technical field

The utility model relates to welding backing.

Background technology

Ceramic welding backing single welding is a kind of high efficiency welding method, widespread usage in shipbuilding industry at present.The ceramic welding backing is the critical material of this welding, it is to connect into Len req by spacer block, is mounted on to form on the aluminum foil and adhesive tape.Because the welding point of Ship Structure linear has linear, camber line shape, circular arc is linear and knuckle is linear etc., therefore developed over one hundred kind of difformity and the miscellaneous spacer block of specification, to adapt to the needs of welding point.The shortcoming of commercially available welding backing piece is: it can only be used for rectilinear welding point.When being used to have the linear welding point of curvature, two spacer block junctions can not closely connect up and down because bending is arranged, and present the wide gap of sharp del down between two spacer block, and this causes the welding point sealing run to be the ring shape, influences weldquality.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of convenient bending, can adapt to the welding backing of the needs of different welding points.In order to solve above technical problem, the utility model by the following technical solutions:

It is formed by connecting by a plurality of end to end liner monomers, the stem of described liner monomer and afterbody are respectively and protrude and recessed circular arc, the profile of the circular arc of described stem and afterbody is worked in coordination, and also is provided with in the bottom of a plurality of liner monomers they are connected and to be fixedly coupled band.

By above technical scheme, after the utility model bending, end to end liner monomer still closely links together, wherein can not produce the slit, the needs that can adapt to the linear welding point of difference, thereby avoid producing many difform spacer block, reduce production costs in order to adapt to different joints.

The specific embodiment

With reference to accompanying drawing 2, the utility model is formed by connecting by a plurality of end to end ceramic backing monomers 1, and the bottom of described a plurality of liner monomers also is provided with they connections and is fixedly coupled is with 4.When the utility model is made, earlier liner monomer 1 is connected into Len req, be mounted on the connecting band 4 fixing again.

With reference to accompanying drawing 1.The stem 2 of described liner monomer and afterbody 3 are respectively and protrude and recessed circular arc, the profile of the circular arc of stem and afterbody is worked in coordination, and this design is can both closely link together under the linear condition of different welding points between the liner monomer in order to guarantee.In the present embodiment, the semicircle of stem for protruding, afterbody is recessed semicircle.The semicircle liner monomer of front and back when bending that can guarantee to greatest extent can be combined closely.

With reference to accompanying drawing 3, in the time of the utility model tiling, can be used for the linear welding point, use as common liner.

With reference to accompanying

drawing

4,5,6, after the utility model bending, end to end liner monomer still links together, and wherein can not produce the slit, the needs that can adapt to different linear welding points 5 are such as the welding point linear than arc welding point, the knuckle of deep camber etc.

In the present embodiment, connecting band 4 is an aluminum foil and adhesive tape, and adopting aluminium foil is because it has ductility and high temperature resistance preferably.In the time of the utility model bending, can also further tighten the distance between monomer and the monomer, to reach best result of use by adjusting this aluminum foil and adhesive tape 4.

When the utility model uses, can also combine with general pad, only use the utility model transition in bending, common ceramic backing is used in straight place, saves cost to greatest extent.

Claims
