Abstract
The present invention relates to a novel groove for welding, which comprises two steel plates, Y type welding groove and U type welding grooves. The present invention is characterized in that the Y type welding grooves are welded on the front surfaces of the steel plates, and the Y type welding grooves are butted by the steel plates and a 1Y type groove and a 2Y type groove which are respectively processed by the steel plates; U type welding grooves are butted on the corresponding reverse surfaces by the steel plates and a 1U type groove and a 2U type groove which are respectively processed by the steel plates, wherein the groove angles of the Y type welding grooves are from 30 degrees to 35 degrees, and the groove depth is 1/2 plate thickness +of 3mm; the groove angles of the U type welding grooves are from 30 degrees to 35 degrees, the width of the bottom surfaces is from 8mm to 10mm, and the radii of the transiting round angles are from 3mm to 5mm; the distance between the bottom surfaces of the Y type welding grooves and the bottom surfaces of the U type welding grooves is from 1.5mm to 2.5mm. The present invention adopts the YU mixed type welding grooves to reduce the root clearing workload of carbon arc gouging. The surfaces of the grooves are tidy, the repair rate of the welding of medium plates can be reduced, and welding one-time qualified rate is improved. The present invention is favorable to productivity improvement.
Description
(1) technical field
The present invention relates to welding procedure, particularly relate to a kind of YU mixed type bevel for welding.
(2) background technology
Thickness steel plate is welded as and guarantees its weld seam internal soundness in existing, the X types that adopt see that Fig. 3 or Y type see Fig. 2 bevel for welding more, after the front welding is finished, reverse side adopts manual carbon arc air gouging to do back chipping work, in the back chipping process, the original groove of reverse side dug and become to be similar to the U type, because of the carbon arc air gouging method is subjected to manual restriction, be difficult to guarantee reverse side weld groove quality, be the destabilizing factor that influences reverse side weld seam internal soundness.The concrete manifestation form is seen Fig. 4, in the construction, the actual gouge groove shape of weld seam reverse side and original X type or Y type groove shape have very big-difference at the scene, because manual gouge causes the groove face out-of-flatness, the whole piece weld seam is not straight, therefore, weld defect appears at the reverse side weld seam mostly.In addition, because groove angle is spent suddenly behind the gouge, cause electric arc directive property bad, weld edge is difficult for fusion.Want to reach the perfect condition groove, among Fig. 4 in the dotted line redundance all need exclude and become U type weld groove and could improve the reverse side welding quality.
(3) summary of the invention
The technical problem to be solved in the present invention is to improve the welding first-time qualification rate, guarantees the mechanical performance of materials to be welded, reduces a kind of YU mixed type groove that welds usefulness of carbon arc air gouging back chipping workload or cancellation carbon arc air gouging back chipping operation.
The technical scheme that adopts is:
A kind of welding groove, comprise steel plate, Y type bevel for welding, U type bevel for welding, described Y type bevel for welding is located at two block plate fronts of welding, the 1/2Y type groove of being processed separately by two block plates is to being connected into Y type bevel for welding, the 1/2U type groove that corresponding reverse side is processed separately is to being connected into U type bevel for welding, the bevel angle of its Y type bevel for welding is 30 °-35 °, groove depth is 0.5 δ+3mm, δ is a thickness of slab, the angle of U type bevel for welding is 30 °-35 °, and the bottom surface is wide to be 8-10mm, and its knuckle radius R is 3-5mm, the spacing of the bottom surface of Y type bevel for welding and U type bevel for welding base plane is 1.5-2.5mm, constitutes YU mixed type bevel for welding.
The present invention adopts YU mixed type bevel for welding, reduces the back chipping workload of carbon arc air gouging, and groove face is smooth, in can reducing, thickness steel plate welding repair rate, improves the welding first-time qualification rate, helps the raising of productivity ratio.

Fig. 2 is a Y type divided edge structure schematic diagram.
Fig. 3 is an X type divided edge structure schematic diagram.
Fig. 4 is that X type or Y type bevel for welding adopt carbon arc air gouging back chipping schematic diagram.
(5) specific embodiment
A kind of welding groove comprises steel plate 1, steel plate 2, Y type bevel for welding 3, U type bevel for welding 4.On steel plate 1 and steel plate 2, respectively adopt machining process to be processed into 1/2Y type groove in the front, be processed into 1/2U type groove at reverse side, the front is to being connected into Y type bevel for welding 3 during welding, reverse side is to being connected into U type bevel for welding 4, constitute YU mixed type bevel for welding, wherein the bevel angle of Y type bevel for welding 3 is 30 °, the bevel angle of U type bevel for welding 4 is 30 °, the groove depth of Y type bevel for welding 3 is 0.5 δ+3mm, thickness of slab δ=45mm, the dark 25mm of the groove of Y type bevel for welding 3 then, the wide 8mm in bottom surface of U type bevel for welding 4, its knuckle radius R is 5mm, the spacing of the bottom surface of Y type bevel for welding 3 and U type bevel for welding 4 base plane is 2mm.
