The inclined end portion is adjacent；
The groove extends from the circular sliding slopes section to the first weldment side；
The root gap is vertically disposed at below the groove.
Preferably, the groove is arranged at the first weldment bottom.
Preferably, the inclined end portion of second weldment extends towards first weldment, in the groove
Support boss formed below.
Preferably, the height of the support boss is 4-5mm.
Preferably, the end of first weldment is arranged in vertical.
Preferably, the inclined end portion of second weldment and the angle of vertical direction are 5-10 °.
Preferably, arc radius R >=10mm of the circular sliding slopes section.
Preferably, the width P of the root gap is 1-2mm.
Preferably, the width C of the groove is 4-5mm.
Preferably, the height A of the groove is 4-5mm.
Compared with prior art, the beneficial effects of the invention are as follows the end of thick weldment to cave inward, and is formed recessed
Groove, so as to both can guarantee that through welding weldment, while the volume of divided edge structure is reduced again, reach reduction wlding
Consumption, the effect for reducing welding job amount.

Embodiment
Preferred embodiment of the present disclosure is more fully described below with reference to accompanying drawings.Although this is shown in accompanying drawing
Disclosed preferred embodiment, however, it is to be appreciated that may be realized in various forms the disclosure without should be by here
The embodiment of elaboration is limited.On the contrary, these embodiments are provided so that the disclosure is more thorough and complete,
And the scope of the present disclosure can be intactly communicated to those skilled in the art.
Fig. 2 shows the asymmetric narrow gap welding divided edge structure according to exemplary embodiment, and it is arranged at
Between one weldment 1 and the second weldment 6, for the first weldment 1 and the second weldment 6 to be welded on
Together.It is more than according to the asymmetric narrow gap welding divided edge structure of exemplary embodiment especially suitable for thickness
The welding of 30mm thick weldment.
Include what is be sequentially communicated from top to bottom according to the asymmetric narrow gap welding divided edge structure of exemplary embodiment
Low-angle groove section 7, circular sliding slopes section 5, groove 2 and root gap 3.Wherein low-angle groove section 7
Between the inclined end portion of the end of the first weldment 1 and the second weldment 6, low-angle groove section 7 is opened
