Using said method, by arranging base plate, core body and collar, bossing and non-bossing are enable by ring
Ground positioning, then welded, processing purpose is reached, compare the whole machine for if possible adopting and be integrally formed, it is more cost-effective, while
It is high in machining efficiency on the premise of economy is ensured, the bossing of some monomers and non-bossing can be welded into again
Loop configuration forms the annular panel beating housing for needing.
Used as the preferred version of the present invention, the plate upper surface is detachably provided with the first stopping means, step C
In, the bottom of the bossing and non-bossing is coordinated by first stopping means and core body to be fixed, and locating effect is more
It is good, while in welding process, preferably reducing the deformation of workpiece.
Used as the preferred version of the present invention, in step B, when arranging the fixture, fixture also includes pressing plate（Increase spacing
Effect）, the pressing plate lower surface is detachably provided with the second stopping means, and collar is completed after fit described in step C, described
Pressing plate is matched with core body top, and the top of the bossing and non-bossing is matched somebody with somebody by second stopping means and core body
Close and fix, locating effect is more preferable, while in welding process, preferably reducing the deformation of workpiece.
Used as the preferred version of the present invention, first stopping means and the second stopping means are loop configuration, annular
Carry out to bossing and non-bossing positioning, locating effect more preferably, while in welding process, preferably reducing
The deformation of workpiece.
As the present invention preferred version, in step A, the bossing and non-bossing it is supporting after carry out repair,
The locating effect of bossing and non-bossing is further ensured that, while being compared to the mode of single high request, repair is more
It is cost-effective.
Used as the preferred version of the present invention, in step C, the bossing and non-bossing are completed after installation, in institute
Stating the gap between bossing and non-bossing carries out tack welding, and the first stopping means and the second stopping means coordinate, and make
General orientation effect more preferably, lifts the effect of welding.
Used as the preferred version of the present invention, in step D, after being welded, the annular panel beating housing to being formed goes de-stress,
The quality after toroidal shell is finally machined is lifted, reduces the possibility for deforming upon.
As the preferred version of the present invention, in step D, X-ray detection is carried out to annular panel beating housing after destressing, and it is right
Poor weld carries out repair welding, be further ensured that toroidal shell finally machine after quality.
As the preferred version of the present invention, in step D, when being welded, alternately weld with the weld seam of core body formed symmetrical,
In welding process, the deformation of workpiece is preferably reduced.
Compared with prior art, beneficial effects of the present invention：
It is cost-effective, high in machining efficiency and the bossing of some monomers and non-bossing can be welded into ring junction configuration
Into the annular panel beating housing for needing.
