Warm cold water carries out cooling processing to obtain the lower cooling water of temperature.
Finally by arc tube panel as follows by the welding corresponding with Ni-based pipe of each Ni-based band steel：
First to the one side of tube panel（It is considered as the front of tube panel）Carry out symmetrical interval welding：The welding sequence of each Ni-based band steel
For：Welding is located at No. five band steels 11 in tube panel centre position first, and using the axis of No. five band steels 11 as symmetry axis, then will
Eight Ni-based band steels positioned at symmetry axis both sides carry out symmetrical interval welding：After being soldered No. five band steels 11, then seven are welded successively
Number band steel 15 of band steel 9, nine of band steel 13, three and No.1 band steel 7, just complete at this time to the Ni-based of tube panel frontal width direction
One wheel welding of band steel；Then a wheel remaining also unwelded two wheel of Ni-based band steel progress is welded again to be alternately symmetrically welded,
Welding sequence is：No. six band steels 14 of band steel 10, eight of band steel 12, four and No. two band steels 8, tube panel is positive all Ni-based at this time
Band steel has just all been soldered；The welding manner of the Ni-based band steel of single is：Welded respectively to its both ends from the centre of Ni-based band steel,
And using symmetrical interruption welding manner, i.e., often after the weld seam of welding 200mm length, the weld seam for being intended to interruption 200mm length does not weld
It connects.
Then by tube panel turn-over again to its another side（That is the reverse side of tube panel）Carry out symmetrical interval welding：Each nickel of tube panel reverse side
The welding sequence of base band steel 2 is identical as positive each welding sequence of Ni-based band steel；When welding single Ni-based band steel 2, from
The centre of Ni-based band steel is welded to its both ends respectively, and uses uninterrupted welding manner, i.e., when welding every Ni-based band steel,
Disposably by the weld seam of whole Ni-based band steel, all weldering is full；
Finally by tube panel, turn-over is full all to weld its positive place of weldering again：The welding sequence of each Ni-based band steel is：
The whole welderings of intermittent No. five band steels 11 will be welded completely positioned at having for tube panel centre position first, and with the axis of No. five band steels 11
As symmetry axis, then the intermittent eight Ni-based symmetrical interval welding of band steels progress will be welded positioned at having for symmetry axis both sides：
I.e. by No. five band steels 11 after all weldering is full, then No. seven band steels 15 of band steel 9, nine of band steel 13, three will be welded successively and No.1 is flat
All weldering is full for steel 7, and just complete has tube panel front the wheel welding for welding intermittent Ni-based band steel at this time；Then again by one
Wheel welding is remaining, and also with intermittent Ni-based two wheel of band steel progress is welded, alternately balanced welding full weld connects, and welding sequence is：No. six
The band steel 14 of band steel 10, eight of band steel 12, four and No. two band steels 8, the at this time positive all Ni-based band steels of tube panel just all welderings
It is full；The welding manner of single Ni-based band steel is：It is welded respectively to its both ends from the centre of Ni-based band steel, until will be whole Ni-based
All weldering is full for band steel.
The tube panel of the present invention uses the welding manner being symmetrically spaced, when being welded to No. five band steels 11, due to
Just start to weld, so the temperature of No. five band steels 11 and the Ni-based pipe positioned at its both sides is room temperature, so flat in welding five
When steel 11, No. five band steels 11 and the Ni-based pipe positioned at its both sides will not deform substantially, after the completion of No. five band steels 11 weld,
When being welded again to No. seven band steels 13, since centre is across two Ni-based pipes and No. six band steels 12 so that by welding five
Number band steel 11 and the heat that generates is not transferred on No. seven band steels 13, so when being welded to No. seven band steels 13, No. seven
The temperature of band steel 13 and the temperature of Ni-based pipe positioned at its both sides are almost similarly room temperature, it can be ensured that No. seven 13 Hes of band steel
Ni-based pipe positioned at its both sides will not deform substantially, after the completion of No. seven band steels 13 weld, then be welded to No. three band steels 9
When connecing, similarly, it is ensured that No. three band steels 9 and the Ni-based pipe positioned at its both sides will not deform substantially, and so on, it completes
Welding to nine Ni-based band steels, to ensure that entire tube panel will not deform substantially in the welding process.Meanwhile balanced welding
Connecing mode itself can also prevent Ni-based pipe and Ni-based band steel from deforming to a certain extent, because in the process being symmetrically welded
In, because the deformation that the Ni-based band steel of side and Ni-based pipe generate can be by the change of the Ni-based band steel of the other side and the generation of Ni-based pipe
Shape is cancelled out each other, so can be further ensured that entire tube panel will not deform.In addition, the tube panel of the present invention is welding it just
When all Ni-based band steels in face, the mode for being all made of symmetrical interruption welding is from it that is, when welding every Ni-based band steel
What centre was welded to both ends respectively, and often after the weld seam of welding 200mm length, the weld seam for being intended to interruption 200mm length does not weld,
After the weld seam of the 200mm length among Ni-based band steel is soldered, the weld seam that be interrupted 200mm length does not weld so that because of weldering
Connect the weld seam of the 200mm length among Ni-based band steel and the heat that generates will be passed to the interruption of coupled 200mm length
Weld seam, only fraction of energy will be transmitted on the weld seam that next section needs the 200mm length welded, to this section of 200mm long
The Ni-based pipe and Ni-based band steel of the weld seam both sides of degree have lower temperature, so when welding the weld seam of this section of 200mm length,
The Ni-based pipe and Ni-based band steel of its both sides will not deform substantially, and so on, the welding to nine Ni-based band steels is completed, from
And ensureing entire tube panel will not deform substantially in the welding process.In addition, the length of the welded seam and intermittent weld
Degree is clearly to be determined by the length of Ni-based band steel and Ni-based pipe,.
Above-mentioned all welding operations are all made of manual electric arc welding welding, it is contemplated that Ni-based band steel and Ni-based pipe fire check are inclined
To larger characteristic, fire check is generated in cooling procedure in order to be effectively prevented weld seam, needs use and nickel-base material phase
Matched weld heat input and temperature between controlling, find by inventor's test of many times, between leading to cooling water control road in pipe
When temperature, the weld heat input that manual electric arc welding uses controls between 10-15KJ/cm, can be very well protected from weld seam
Fire check is generated, weld heat input is 12KJ/cm used in the present embodiment.
In conclusion the Ni-based tube panel that welding method using the present invention is welded, will not deform and generate
Fire check, to ensure that the dimension precision requirement of Ni-based tube panel, meanwhile, the amount of reprocessing of Ni-based tube panel is also reduced, is shortened
