It is immature due to existing welding procedure when processing grinding machine, incinerating kiln, dry kiln when large-size cylinder bodies, lead to cylinder
There is the problem of weld defect and stress concentration in body, and the stability of welding performance is bad.
Invention content：
The technical problem to be solved by the invention is to provide it is a kind of facilitate welding and welding effect it is good large-size cylinder body welding
Technique.
The technical solution of the present invention is to provide a kind of large-size cylinder body welding procedure, includes the following steps, cylinder steel plate
Blanking, ultrasonic examination periphery 120mm, it is desirable that II grade of qualification；Second step, ring flat-plate open splicing groove, and cylinder is opened vertical masonry joint groove, beaten
After stain flaw detection is ground, notices that cylinder board length is less than actual size length 2-3mm；Ring flat-plate splices, manual welding bottoming, pre- before weldering
Heat, preheating temperature >=100 DEG C add run-on tab, submerged-arc welding, submerged-arc welding after back chipping, postweld heat preservation behind tune face；Plate is rolled, after card is round
Welding straight-line joint, manual welding bottoming, preheating temperature >=100 DEG C add run-on tab, submerged-arc welding, and submerged-arc welding after back chipping, postwelding return behind tune face
Reel section, Hui Yuan at vertical masonry joint；Vehicle shell ring internal diameter goes out white to ring flat-plate weld；Vehicle ring flat-plate smooths bottom surface, by shell ring internal diameter -1mm,
Turning, vehicle go out the unilateral J-type groove in upper surface；Weld-ring plate and shell ring, solid point, manual welding bottoming hang in pivoted frame, and preheating temperature >=
100 DEG C, submerged-arc welding, it is desirable that fillet welding height >=20mm；Vehicle Processing other end J-type groove, digging are deep to weld, go out white, commissure
Dye penetrant inspection；Hang in pivoted frame, preheating temperature >=100 DEG C, submerged-arc welding, it is desirable that fillet welding height >=20mm；Vehicle Processing groove R20mm, goes out
White ring plate plane processes shell ring hipped end mouth；Welding stress is eliminated, is examined.
Using compared with prior art, the present invention has the following advantages after process above：Welding procedure is simple, can be to avoid
Occur weld defect during barrel soldering, ensure the stability of welding, the intensity after barrel soldering is high, rigidity is good.
Specific embodiment：
With regard to specific embodiment, the invention will be further described below：
A kind of large-size cylinder body welding procedure, includes the following steps, cylinder steel plate cutting, ultrasonic examination periphery 120mm,
Seek II grade of qualification；Second step, ring flat-plate open splicing groove, and cylinder opens vertical masonry joint groove, and polishing after stain flaw detection pays attention to cylinder board length
It is less than actual size length 2-3mm；Ring flat-plate splices, and manual welding bottoming, weld preheating, preheating temperature >=100 DEG C add striking
Plate, submerged-arc welding, submerged-arc welding after back chipping, postweld heat preservation behind tune face；Roll plate, welding straight-line joint after card is round, manual welding bottoming, preheating temperature
>=100 DEG C of degree, adds run-on tab, submerged-arc welding, submerged-arc welding after back chipping behind tune face, postwelding backrush shell ring, Hui Yuan at vertical masonry joint；In vehicle shell ring
Diameter goes out white to ring flat-plate weld；Vehicle ring flat-plate smooths bottom surface, and by shell ring internal diameter -1mm, turning, vehicle goes out the unilateral J-type slope in upper surface
Mouthful；Weld-ring plate and shell ring, solid point, manual welding bottoming hang in pivoted frame, preheating temperature >=100 DEG C, submerged-arc welding, it is desirable that and fillet welding height >=
20mm；Vehicle Processing other end J-type groove, digging are deep to weld, go out white, commissure dye penetrant inspection；Hang in pivoted frame, preheating temperature
>=100 DEG C, submerged-arc welding, it is desirable that fillet welding height >=20mm；Vehicle Processing groove R20mm goes out white ring plate plane, processes shell ring hipped end mouth；
Welding stress is eliminated, is examined.
This technique welding procedure is simple, weld defect occurs when can be to avoid barrel soldering, ensures the stability of welding, cylinder
Intensity after body welding is high, rigid good.
