Description
Technical field
The utility model relates to welding technology field, refers in particular to a kind of melt-through weld structure with liner plate.
Background technology
Usually, when the penetration welding carrying out belt material plate welding seams, easily there is the problem of incomplete fusion or the defect such as lack of penetration in the root of weld, thus cause weld joint ultrasonic to detect the not high phenomenon of qualification rate.Fig. 1 is the melt-through weld structural representation of existing band liner plate, consult shown in Fig. 1, when the welding of melt-through weld 70 carrying out steel plate 60, easily there is incomplete fusion or the defect such as lack of penetration in the bottom of melt-through weld 70, as shown in Figure 1, at the root of melt-through weld 70 near the place of liner plate 80, solder 90 fails fully to fill up the melt-through weld 70 of steel plate 60, thus occurs the defect in space 91.
Therefore, how solving incomplete fusion that melt-through weld root easily occurs or the defect such as lack of penetration, is this area difficult problem urgently to be resolved hurrily.
Utility model content
Because in above-mentioned prior art easily there is the problem of incomplete fusion or the defect such as lack of penetration in melt-through weld root, the purpose of this utility model is, solve and carrying out the penetration welding of belt material plate welding seams constantly, the incomplete fusion that melt-through weld root easily occurs or the defect such as lack of penetration.
For achieving the above object, the utility model provides a kind of melt-through weld structure with liner plate, comprising:
Steel plate, described steel plate is formed with weld groove;
Pad the liner plate be located at below described steel plate, described liner plate is formed with the blanking port communicated with described weld groove.
The melt-through weld structure of the utility model band liner plate, by forming the blanking port communicated with the weld groove of steel plate on liner plate, during weld seam welding, make solder fully can fill up the weld groove of steel plate and the space between steel plate and liner plate, thus easily there is the defects such as lack of penetration and incomplete fusion at weld groove root when avoiding weld seam welding, ensure the first-time qualification rate of weld seam welding.
The further improvement of the melt-through weld structure of the utility model band liner plate is, the shape of the shape of described blanking port and the root of described weld groove is suitable.
The further improvement of the melt-through weld structure of the utility model band liner plate is, described weld groove and described blanking port rounding off.
The further improvement of the melt-through weld structure of the utility model band liner plate is, described weld groove is double V-groove or U-shaped groove.
The further improvement of the melt-through weld structure of the utility model band liner plate is, described blanking port is the groove of band arc.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Coordinating consults shown in Fig. 2, and the melt-through weld structure of band liner plate of the present utility model, comprising: steel plate 10 and liner plate 20.
Steel plate 10, steel plate 10 is formed with weld groove 110.Preferably, weld groove 110 is double V-groove or U-shaped groove.
Liner plate 20, the below of steel plate 10 is located at by pad, and liner plate 20 is formed with the blanking port 210 communicated with the weld groove 110 of band steel liner plate 10, the shape of the shape of blanking port 210 and the root of weld groove 110 is suitable, further, blanking port 210 and weld groove 110 rounding off.Preferably, blanking port 210 is the groove of band arc.
The melt-through weld structure of band liner plate of the present utility model, when practical operation, has following two kinds of manufacture crafts:
Manufacture craft one: consult shown in Fig. 2, it is the structural representation that the melt-through weld structure of band liner plate of the present utility model adopts the first manufacture craft, wherein, liner plate 20 is fixedly connected with steel plate 10, and the weld groove 110 of steel plate 10 and the blanking port 210 of liner plate 20 are by processing technology one-shot forming.Particularly, by being thickeied by liner plate 20, the root of the weld groove of steel plate 10 can be excluded a part together with liner plate 20, then bottoming welding, thus easily there is the defects such as lack of penetration and incomplete fusion at root when avoiding weld seam to weld, ensure the first-time qualification rate of weld seam welding.After having welded, liner plate 20 can be removed.
Manufacture craft two: consult shown in Fig. 3, it is the structural representation that the melt-through weld structure of band liner plate of the present utility model adopts the second manufacture craft, wherein, liner plate 20 and steel plate 10 are independent workpiece, the weld groove 110 of steel plate 10 and the blanking port 210 of liner plate 20 shaping respectively by respective processing technology.
Shown in composition graphs 4, it is the effect schematic diagram of the melt-through weld structure of band liner plate of the present utility model, the melt-through weld structure of the utility model band liner plate, by forming the blanking port 210 communicated with the weld groove 110 of steel plate 10 on liner plate 20, during weld seam welding, make solder 30 fully can fill up the weld groove 110 of steel plate 10 and the space between steel plate 10 and liner plate 20, thus easily there is the defects such as lack of penetration and incomplete fusion at the root of weld groove 110 when avoiding weld seam welding, ensure the first-time qualification rate of weld seam welding.
The above is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, not departing from the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
