Description

The joint design and welding method of a kind of tube butt welding
Technical field
The present invention relates to the joint design and welding method of a kind of tube butt welding.
Background technology
The tube wall of temperature gas cooled reactor steam generator heat exchanger tube is thicker, and butt welding requirement is higher, pipe assembling unfitness of butt joint, weldering Inwall bulge quantity, outer wall amount of recess should be less than certain value afterwards.Further, since actual welding locus is smaller, heat exchanger tube Between minimum range there was only 40mm, according to landfilling area, because space is smaller between partial tube the wire feeder can be caused cannot to arrive Reach, it is difficult to realize welding；Serve as packing material with reference to automatic heliarc Welding according to melting ring, although all positon can be realized Welding, but it is difficult to ensure that assembling unfitness of butt joint and convex, outer recessed requirement.
The content of the invention
The present invention provides the joint design and welding method of a kind of tube butt welding, reduces unfitness of butt joint during assembling, makes Joint convex, the outer recessed stability for meeting design requirement, improve welding quality and welding.
In order to achieve the above object, the present invention provides a kind of joint design of tube butt welding, comprising：First is arranged on to connect The convex root face of pipe end, the spill root face and melting ring that are arranged on the second adapter end.
Described convex root face is arranged on end face and the inwall junction at the first adapter end, and described spill root face is arranged on The end face at the second adapter end and inwall junction.
The height of described convex root face is equal to the thickness of melting ring and the depth sum of spill root face, the thickness of convex root face Thickness of the degree equal to spill root face.
The internal diameter of described melting ring is equal to the external diameter of convex root face, the external diameter of the external diameter more than adapter of melting ring.
The present invention also provides a kind of method of tube butt welding, comprises the steps of：
Step S1, respectively processing convex root face and spill root face in two adapters for need welding, and melting ring is processed, The size of convex root face, spill root face and melting ring is mutually matched；
Step S2, melting ring is placed between two adapter end faces, makes convex root faces and spill in two adapters blunt Side position is mutually matched；
Step S3, using melting ring as packing material, carry out automatic heliarc welding, complete the all-position welding of adapter.
The present invention processes convex root face and spill root face respectively in adapter end face, and using the technique of addition melting ring, drop Unfitness of butt joint during low assembling, makes joint convex, evagination meet design requirement, improves the stabilization of welding quality and welding Property.

Specific embodiment
Below according to Fig. 1~Fig. 5, presently preferred embodiments of the present invention is illustrated.
As shown in figure 1, the present invention provides a kind of joint design of tube butt welding, comprising：It is arranged on the first adapter end 11 On convex root face 1, the spill root face 2 and melting ring 3 (as shown in Figure 4) that are arranged on the second adapter end 22.
As depicted in figs. 1 and 2, described convex root face 1 is arranged on end face and the inwall junction at the first adapter end 11.Such as Shown in Fig. 1 and Fig. 3, described spill root face 2 is arranged on end face and the inwall junction at the second adapter end 22.
As shown in figure 5, the height H1 of described convex root face 1 is equal to the thickness H3 of melting ring 3 and the depth of spill root face 2 H2 sums, the thickness of convex root face 1 is equal to the thickness of spill root face 2, the height of convex root face 1, the thickness of spill root face 2 and molten The depth for changing ring 3 is to actual welding material and related from welding parameter.The internal diameter of melting ring 3 is equal to the external diameter of convex root face 1, The external diameter of melting ring 3 depending on the outside dimension visual fusion ring thickness and welding parameter of melting ring 3, is taken over more than the external diameter of adapter Outside dimension do not limit, as long as less than welding head clamp diameter, 1~5mm of adapter wall thickness.
The present invention also provides a kind of tube butt welding method, comprises the steps of：
Step S1, respectively processing convex root face 1 and spill root face 2 in two adapters for need welding, and process fusing Ring 3, the size of convex root face 1, spill root face 2 and melting ring 3 is mutually matched；
The height of described convex root face 1 is equal to the thickness of melting ring 3 and the depth sum of spill root face 2, convex root face 1 Thickness be equal to the thickness of spill root face 2, the internal diameter of melting ring 3 is equal to the external diameter of convex root face 1, and the external diameter of melting ring 3 is more than The external diameter of adapter；
Step S2, melting ring 3 is placed between two adapter end faces, makes the convex root faces 1 and spill in two adapters The position of root face 2 is mutually matched；
Step S3, using melting ring 3 as packing material, carry out automatic heliarc welding, complete the all-position welding of adapter.
In the present embodiment, automatic helium is carried out using the steam generator pipe butt welding closed welding head of special L-type Arc welding, back is protected using argon gas, and core is protected using helium, position is taken in whole welding process and is maintained static, and is welded Rifle is rotated around adapter, and tungsten electrode is rotated, and welding head is clamped on pipe, the welding of 2G positions.
Compared to landfilling area, the present invention can realize the all-position welding of steam generator heat-transfer pipe, right in welding process The requirement in space is smaller, and weldquality meets related request after butt welding, compared to the mode for only adding melting ring, this hair Bright unfitness of butt joint when can utilize convex root face and the reduction assembling of spill root face, make joint convex, it is outer it is recessed meet design requirement, and And melting ring can play fixation in assembling using convex root face and spill root face, can further improve welding quality and The stability of welding.
Although present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned Description is not considered as limitation of the present invention.After those skilled in the art have read the above, for of the invention Various modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
