Description
Technical field
The present invention relates to pipeline engineering field, specifically a kind of group of posted sides pipeline groove is to method.
Background technology
Pipe string is a step important in pipeline welding control, and the control of groove gap is a difficulty of pipe string
Point, especially for pressure pipeline, the quality of groove gap adjustment directly influences the welding quality of pipeline, generally pipeline
Welding uses single face welding and double face shaping, so typically using argon tungsten-arc welding in pipeline welding, such a welding method is most favourable
In the internal soundness for ensureing pipeline welding.But when posted sides pipeline welds, because welding penetration is big, often in welding process
In with the input of heat produce welding deformation, have a strong impact on pipeline welding quality, it is therefore necessary to strictly to control groove
Gap.The method of adjustment of general groove gap has two kinds, and one kind is fixed by spot welding gusset, but can injure mother metal；Separately
One kind is direct spot welding after assembling, but is unfavorable for controlling the size in gap, so as to influence welding quality.
The content of the invention
It is an object of the present invention to provide one kind will not only injure mother metal, meanwhile, improve welding quality control welding and become
The group of shape is to method.
In order to achieve the above object, the present invention is realized in：
A kind of group of posted sides pipeline groove is to method, including workbench, pipeline location frame, gap adjustment chi, gap locating piece,
Described group includes to method
Step 1, two segment pipes that needs are docked are placed on workbench；
Step 2, with locating rack two segment pipes are fixed into workbench both sides respectively；
Step 3, gap adjustment chi inserted in the gap between two segment pipes, gap adjustment chi is fitted in any one section of pipe
At road port；
Step 4, two segment pipes of adjustment, make gap adjustment chi while be bonded two segment pipes；
Step 5, the gap location insertion gap locating piece in two segment pipes described in step 4；
Step 6, gap locating piece is put respectively at 0 °, 90 °, 270 ° of groove circular arc for being welded in two segment pipes, step 7, by pipeline
After the completion of gap locating piece, spot welding behind 180 ° of sides of upset on 180 ° of directions of spot welding, mobile group is to good pipeline to workbench
Opposite side carry out complete solder；
Step 6, gap locating piece is removed, pipeline is entered welding sequence, used after the completion of bottoming welding or segmentation bottoming welding
Abrasive machine polishing removes point weld clearance locating piece.
The group of described posted sides pipeline groove is in method, the section of gap adjustment chi is in inverted " V " font.
For the group of described posted sides pipeline groove to method, the two sides of gap locating piece are inclined, the angles of its inclined plane
Spend with treating that group is identical to the inclined plane angle of pipeline end face, i.e., when two segment pipe groups are to completing, gap locating piece both sides and pipe
Road end face is bonded completely.
This group to method using gap locating piece come the gap between accurate control pipeline, meanwhile, the gap locating piece is
It can remove, therefore pipeline not caused to damage, therefore for this method is compared to traditional pipe string method, there is group
The advantages of, group fast to speed is good to effect.
Brief description of the drawings
Fig. 1 is that this group adjusts schematic diagram to the tube groove gap of method.
Fig. 2 is A-A in Fig. 1 to sectional view.
Fig. 3 is partial enlarged drawing at the B in Fig. 1.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in Fig. 1 ~ Fig. 3, a kind of group of posted sides pipeline groove to method, including workbench 1, pipeline location frame 3,
Gap adjustment chi 4, gap locating piece 7, described group includes to method
Step 1, two segment pipes 5,6 that needs are docked are placed on workbench 1；
Step 2, with pipeline location frame 3 two segment pipes are fixed into workbench both sides respectively；
Step 3, gap adjustment chi 4 inserted in the gap between two segment pipes 5,6, gap adjustment chi 5 is fitted in arbitrarily
At one segment pipe port；
Step 4, two segment pipes 5,6 of adjustment, make gap adjustment chi 4 while be bonded two segment pipes；
Step 5, the gap location insertion gap locating piece 7 in two segment pipes 5,6 described in step 4；
Step 6, by gap locating piece 7, point is welded at 0 °, 90 °, 270 ° of the groove circular arc of two segment pipes 5,6 respectively,
Step 7, pipeline 5,6 is overturn to gap locating piece 7 behind 180 ° of sides on 180 ° of directions of spot welding, after the completion of spot welding, mobile group
Complete solder is carried out to the opposite side of good pipeline to workbench 1；
Step 6, gap locating piece 7 is removed, pipeline 5,6 is entered welding sequence, after the completion of bottoming welding or segmentation bottoming welding
Polished using abrasive machine and remove point weld clearance locating piece.
The group of described posted sides pipeline groove is in method, the section of gap adjustment chi 4 is in inverted " V " font.
For the group of described posted sides pipeline groove to method, the two sides of gap locating piece 7 are inclined, the angles of its inclined plane
Spend with treating that group is identical to the inclined plane angle of pipeline 5,6 end faces, i.e., when two segment pipe groups to complete when, gap locating piece both sides with
Pipeline end face is bonded completely.
This group to method using gap locating piece come the gap between accurate control pipeline, meanwhile, the gap locating piece is
It can remove, therefore pipeline not caused to damage, therefore for this method is compared to traditional pipe string method, there is group
The advantages of, group fast to speed is good to effect.
