Abstract

The invention discloses a single groove butted ship pipeline and a welding method thereof. The single groove butted ship pipeline comprises a section of plain end pipe and a section of groove pipe, wherein the ends of the section of plain end pipe are horizontal cuts and the ends of the section of groove pipe are provided with inclined grooves; the two pipe sections are oppositely arranged to form a single groove which is opened outwards; and during the welding, the two pipe sections are integrally connected by adopting single groove welding. The ship pipeline is simple in structure and has the advantages of greatly reducing the required workload and improving the work efficiency.

Description

A kind of ship pipeline of bevel docking and welding method thereof
Technical field
The present invention relates to ship pipeline field, particularly relate to a kind of ship pipeline and welding method thereof of bevel.
Background technique
The particularity that ship pipeline designs due to it, tube bending is complicated, has a large amount of butt joints, and these butt joints require to adopt bilateral groove to process.Groove refers to that the position to be welded of weldment processes and the groove of the certain geometrical shape be assembled into, common bilateral groove is double V-groove, as Figure 1-3, bilateral groove pipeline comprises the relative pipe fitting 101 in two sections of ends, one end that two sections of pipe fittings are relative has the groove 102 of inclination, the groove of two sections of pipe fittings forms the bilateral groove of V-type of opening laterally relatively, make the groove end of two sections of pipe fittings close to each other during connection pipe fitting, and leave certain space, by welding, two sections of pipe fittings are connected as one again, welded seam 103 is formed between two sections of pipe fittings, the inner side of weld seam and the inwall of pipe fitting are positioned at same level, be consistent trapezoidal of groove bilateral with V-type in the middle part of weld seam, it is outwardly arc surface outside weld seam.
Ship pipeline has the groove pipe fitting of a large amount of needs welding, even if but at present welding robot developed into certain level, also the butt joint of a small amount of regular shape pipe fitting only can have been replaced to weld, and under most cases, welding work still needs to complete welding by hand by workman, and this makes to improve welding efficiency becomes problem in the urgent need to address.
Summary of the invention
The present invention aims to provide a kind of ship pipeline with bevel and the welding method making this kind of pipeline, to increase work efficiency.
The ship pipeline of bevel docking of the present invention, comprise the pipe fitting that two sections of ends are relative, the wherein flat mouth pipe of one section of to be one of them end be horizontal cut, another section is the groove pipe that one of them end has the groove of inclination, the end of two sections of pipe fittings forms the bevel of opening laterally relatively, and the end of two sections of pipe fittings is connected as one by welded seam.
The ship pipeline welding method of bevel docking of the present invention, comprises the following steps:
A, blanking processing flat mouth pipe, one of them end of this pipeline section is horizontal cut; Another blanking processing cut pipe, one of them end of this pipeline section has the groove of inclination;
B, by the horizontal end of flat mouth pipe, and the groove end of groove pipe is staggered relatively;
C, the opposite end of two pipeline sections apply welding formed weld seam, flat mouth pipe and groove pipe are welded as a whole.
The ship pipeline of bevel docking of the present invention and welding method thereof, by the setting of bevel, the volume of groove weld is made to decrease half, this comes can reduce required workload in large quantities under the prerequisite ensureing pipeline join strength, two make the processing quantity of groove pipe decrease half, thus drastically increase working efficiency; Also can reduce the usage quantity of welding wire simultaneously, reduce cost of production; This kind of pipeline structure and welding method, although its structure is extremely simple, achieves beyond thought technique effect by this simple structure being difficult to expect just, effectively improve working efficiency.

Embodiment
A kind of ship pipeline of bevel docking, comprise the pipe fitting that two sections of ends are relative, the wherein flat mouth pipe 11 of one section of to be one of them end be horizontal cut 2, another section is the groove pipe 12 that one of them end has the groove 3 of inclination, the end that the end of two sections of pipe fittings forms bevel 4, two sections of pipe fittings of opening laterally is relatively connected as one by welded seam 5.
The inner side of welded seam 5 and the inwall of pipe fitting are positioned at same level, are the right-angled trapezium consistent with bevel 4 in the middle part of weld seam, are the outwardly cambered surface in middle part outside weld seam.This kind of weld seam area is little, can effectively reduce required workload, increase work efficiency.
A ship pipeline welding method for bevel docking, comprises the following steps:
A, blanking processing flat mouth pipe, one of them end of this pipeline section is horizontal cut; Another blanking processing cut pipe, one of them end of this pipeline section has the groove of inclination;
B, by the horizontal end of flat mouth pipe, and the groove end of groove pipe is staggered relatively;
C, the opposite end of two pipeline sections apply welding formed weld seam, flat mouth pipe and groove pipe are welded as a whole.
The ship pipeline welding method of described bevel docking, in stepb, leaves space between the opposed end of two pipeline sections; And in step C, during welding, adopt CO 2gas carries out protection weldering.Remaining with of space is beneficial to pipeline section from inwall to the full weld of outer wall, and adopts CO 2gas shielded arc welding, then can avoid causing pipeline section to be oxidized in the process of welding.
