Abstract
The utility model relates to a combined type welding backing unit which comprises a supporting block (1), a filler block (2) and a positioning bar (3). The filler block (2) is placed in a groove formed in the top of the supporting block (1) and can be freely replaced. Due to the structure, the combined type welding backing unit can be combined randomly according to different welding environments, only the filler block (2) needs to be discarded after the welding backing unit is used, the supporting block (1) can still be continued to be used, the use efficiency of a welding backing is improved, and material wastage is lowered.
Description
Technical field
The utility model belongs to welding field, is specifically related to a kind of combined welding backing unit.
Background technology
Welding is a kind of processing method that modern industry generally uses, and wherein the bottoming welding is comparatively common, and the total quality of the quality butt welded seam of bottoming welding and the normal operation of equipment have material impact under many circumstances.Existing backing welding connection technology often adopts welding backing, and during welding, welding backing plays the effect that shaping is set off at the welding bead back side, guarantees that the weld metal back-welding shape is good and in smoothing junction with mother metal, avoids producing the defectives such as burn-through or overlap.Fig. 1 is welding backing unit commonly used, and its shortcoming is disposable use, and loss is more.
The utility model content
The purpose of this utility model is to provide a kind of combined welding backing unit, and this flexible structure is easy-to-use, can effectively reduce loss.
The utility model is achieved in that
A kind of combined welding backing unit comprises tray and pad, and the groove that matches with pad is arranged at the tray top, and pad is placed in groove.
Further, be provided with the positioning strip that flexible material is made between tray top groove sidewall and pad.
Further, pad top, described welding backing unit is provided with arc groove.
The utility model provides combined welding backing unit comprises removable pad, after auxiliary welding, can keep tray, only need change pad when using next time, reduced spillage of material, in the situation that be combined into the large scale welding backing, the effect that reduces welding cost is especially remarkable.In addition, when adopting the utility model, tray and pad can be according to aspect demand flexible choices such as the material of welding, techniques, and independent assortment has improved the service efficiency of welding backing.
Description of drawings
Fig. 1 is existing welding backing cell schematics.
Fig. 2 is provided combined welding backing cell schematics by the utility model.
Fig. 3 is a kind of typical combination application mode schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
Fig. 2 is a kind of typical case of the present utility model, comprises tray 1, pad 2 and 3 three parts of positioning strip.Tray 1 top is provided with groove, matches with pad 2 bottoms, and is set in together, and positioning strip 3 is placed between tray 1 top groove and pad 2 sidewalls, and its effect is pad to be fastened on be difficult for landing in tray.Tray 1 and pad 2 can be made by materials such as pottery, metals, and positioning strip 3 can adopt the flexible high-temperature resistant material to make, as asbestos, glass fibre etc.According to the difference of welding situation, the utility model can be processed, be combined into different size and form, Fig. 3 is a kind of typical combination application mode of the present utility model.
During welding, welding backing is fixed on the bevel for welding back side by adhesive tape or mechanical device, and welding backing plays the effect that shaping is set off at the welding bead back side, guarantees that the weld metal back-welding shape is good and in smoothing junction with mother metal, avoids producing the defectives such as burn-through or overlap.After welding finishes, welding backing is removed, taken out pad 2 discarded, tray 1 still can remain to and reuse next time.Owing to only needing the pad of discarded less, therefore reduced material consumption, can reduce welding cost thus, improved the economy of welding.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the utility model.Like this, if of the present utility model these are revised and within modification belongs to the scope of the utility model claim and equivalent technology thereof, the utility model also is intended to comprise these changes and modification interior.
Claims (2)
1. a combined welding backing unit, is characterized in that: comprise tray (1) and pad (2), and described pad (2) is placed in the groove at tray (1) top.
2. combined welding backing as claimed in claim 1 unit, is characterized in that: be provided with flexible positioning strip between tray (1) sidewall and pad (2).
