Abstract
The utility model provides a welding liner suitable for single-side welding of an obtuse angle butt joint connector. The liner comprises a plurality of liner blocks which are in end to end connection; the head surface and the tail surface of each liner block are parallel to each other; a longitudinally welding seam forming groove is formed on the right side of each liner block, namely a surface in contact with the back surface of a welding connector, the two sides of the welding seam groove raise upward so as to form an obtuse angle. When in use, the welding liner provided by the utility model can be tightly adhered to the back side of the obtuse angle butt joint connector, single side welding to an obtuse angle welding connector is ensured, and the purpose of high welding seam quality is achieved.
Description
Technical field
The utility model relates to the welding backing of welding material.
Background technology
The technology of welding backing single face welding two sides moulding is a kind of welded and high efficient method.Shipyard is used the welding that it carries out the welding point of Ship Structure widely both at home and abroad at present.The banjo fixing butt jointing of Ship Structure is except being the straight angle, and the both sides sheet material of the banjo fixing butt jointing that has is upturned along longitudinal axis and forms certain obtuse angle, and in the market also not to the welding backing of this obtuse angle institute particularly suitable.
Summary of the invention
The utility model technical problem to be solved provides and a kind ofly can adapt to the needed welding backing of obtuse angle banjo fixing butt jointing single welding.In order to solve above technical problem, the utility model adopts following technical scheme:
Said liner is formed by connecting the polylith spacer block that connects that joins end to end; Said spacer block stem plane and tail plane are parallel to each other; Said spacer block front promptly is provided with the longitudinal seam forming tank with the face that the welding point back side is contacted; The two sides of said appearance of weld groove are upturned, and form the obtuse angle each other.
Through above technical scheme, when the utility model uses, can closely be mounted on the banjo fixing butt jointing back side, obtuse angle, guarantee that the obtuse angle welding point carries out single welding, reaches the high purpose of weldquality.
Description of drawings
Fig. 1 is the schematic perspective view of the single spacer block of the utility model.
Fig. 2 connects from beginning to end for several spacer block shown in Figure 1 and is mounted on the sketch map on the aluminum foil tape.
Fig. 3 is the user mode sketch map of Fig. 2.
The specific embodiment
The utility model provides a kind of obtuse angle banjo fixing butt jointing welding backing.Said liner is formed by connecting the polylith spacer block 1 that connects that joins end to end; Said spacer block stem plane 2 is parallel to each other with tail plane 3; Said spacer block front promptly is provided with longitudinal seam forming tank 5 with the face 4 that the welding point back side is contacted; The two sides of said appearance of weld groove are upturned, and form the obtuse angle each other.
The face that bears the welding point back side of said front that is spacer block; This face obtuse angle at an angle; Promptly longitudinally axis upwarps certain angle symmetrically to the left and right, and the spacer block front presents an obtuse angle face, and the number of degrees at obtuse angle are that the welding backing piece angle of sticking up that faces up designs by demand.
Groove depth 1.2 ~ the 1.8mm of said appearance of weld groove 5, groove width 5 ~ 8mm.
Said liner is that the spacer block 1 of some quantity is interconnected to needed length and is mounted on the aluminum foil tape 6.
In the utility model, described spacer block stem plane and tail plane can closely cooperate each other, and promptly the head end face of a spacer block can closely be connected with the breech face of another piece spacer block, are no more than 0.3mm in the gap of the junction of its forming tank.
When using; With reference to shape shown in Figure 1; Size factor is on request made the mould of a secondary obtuse angle banjo fixing butt jointing welding backing piece, and compacting, dry and burn till welding backing piece shown in Figure 1 is by shown in Figure 2; The utility model length on demand is mounted on the aluminum foil tape 6 by the some monolithic spacer block 1 shown in Figure 1 that connect of joining end to end and forms.
When the utility model is used at the scene, tear the separate paper on the aluminum foil tape off, press red center line preset on the liner forming tank; Be mounted on the banjo fixing butt jointing back side, obtuse angle, from the positive welding of welding point, promptly reach positive welding then; Both sides obtain the purpose of superior in quality weld seam simultaneously.
Should be noted that at last; Above embodiment is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain, although with reference to preferred embodiment the utility model has been done explanation at length, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the essence and the scope of the utility model technical scheme.
Claims (3)
