Abstract
The invention discloses a kind of ship butt welding process, its innovative point is：Comprise the following steps：(1) groove is prepared：Groove is prepared using edge planer and argon arc gouge；(2) groove processing；(3) weld：Jigsaw area uses twin-wire MIG welding connection technology；Small assembling area automatic fillet welding or semi-automatic fillet welding welding primary structural component and T-shaped component are protected using argon gas；Using dress, welding integrated vertical bone Erection Welding Technology at hull longitudinal manufacture；The inner bottom plating abutment joint of big closure workmanship, deck and double bottom Lincoln weld capping, position is changed greatly in the line style such as hull stem and afterbody, welded using argon gas protection weldering using the weldering bottoming of argon gas ceramic backing；Manual electric arc welding method is used in closed and small space.The welding method of the present invention, welding efficiency is high, and welding deformation is well controlled, and effect improves the welding quality of ship during production practices, cost-effective, improves efficiency.
Description
Technical field
The present invention relates to a kind of welding procedure, and in particular to the High Efficiency Welding Process in a kind of shipbuilding.
Background technology
In the construction of ship, welding is therein crucial and support technology, and during the chief engineer of welding and cost respectively accounts for hull
During the chief engineer of construction and cost 30%-40%, the quality of welding technique is to reflect the important indicator of hull construction quality good or not.
Therefore, research and develop mechanization, the efficient welding technology of automation be not only enterprise improve shipbuilding quality, improve production efficiency,
Reduce construction cost, shorten the effective way of shipbuilding period, and be to realize that the Modern Shipbuilding Mode that ship parent company proposes turns
The technological progress growth point changed.At a high speed and efficient welding is the developing direction of modern welding, be realize modernization welding must
By road.
The content of the invention
The technical problem to be solved in the present invention is to provide the high-efficiency welding method in a kind of shipbuilding, and height is established to realize
Effect, the modern ships efficient welding technology of energy-saving and environmental protection.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
(1) groove is prepared：Groove is prepared using edge planer and argon arc gouge, the compressed air pressure for argon arc gouge
For 0.6~0.8Mpa；
(2) groove processing：Conscientiously check whether groove size and assembling quality meet relevant requirement before weldering；In groove and slope
Positive and negative in each 35mm of mouth both sides of edges removes the viscous carbon of water stain, greasy dirt, iron rust, dross and carbon plane residual with end face；
(3) weld：Jigsaw area uses twin-wire MIG welding welding technique；Small assembling area automatic fillet welding is protected using argon gas
Or semi-automatic fillet welding welding primary structural component and T-shaped component；Using dress, welding integrated vertical bone erecting and welding skill at hull longitudinal manufacture
Art；The inner bottom plating abutment joint of last big closure workmanship, deck and double bottom is using the weldering bottoming of argon gas ceramic backing, Lincoln weld
Capping, position is changed greatly in the line style such as hull stem and afterbody, is welded using argon gas protection weldering；Closed and
Small space uses manual electric arc welding method；The big welding for closing up seam should first weld the coverboard abutment joint between total or segmentation,
Its interstructural butt weld is welded again, then the angle welding of welding structure and coverboard；Fillet welding in the vertical position is first welded, welds flat fillet weld afterwards；Manual welding
When to longer weld seam should use point in symmetrical backstep sequence；It is big close up weld seam assembling inspection declaration it is qualified after, entered in 20 hours
Row welding.
Beneficial effects of the present invention：Compared with traditional welding technique, welding method of the invention, welding efficiency is high, weldering
Connect deformation to be well controlled, effect improves the welding quality of ship during production practices, cost-effective, improves efficiency.
Embodiment
Technical scheme is elaborated with reference to specific embodiment.
A kind of ship butt welding process, it is characterised in that：Comprise the following steps：
(1) groove is prepared：Groove is prepared using edge planer and argon arc gouge, the compressed air pressure for argon arc gouge
Power, generally 0.6~0.8Mpa；
(2) groove processing：Conscientiously check whether groove size and assembling quality meet relevant requirement before weldering；In groove and slope
Positive and negative in each 35mm of mouth both sides of edges removes the viscous carbon of water stain, greasy dirt, iron rust, dross and carbon plane residual with end face；
(3) weld：Jigsaw area uses twin-wire MIG welding welding technique；Small assembling area automatic fillet welding is protected using argon gas
Or semi-automatic fillet welding welding primary structural component and T-shaped component；Using dress, welding integrated vertical bone erecting and welding skill at hull longitudinal manufacture
Art；The inner bottom plating abutment joint of last big closure workmanship, deck and double bottom is using the weldering bottoming of argon gas ceramic backing, Lincoln weld
Capping, position is changed greatly in the line style such as hull stem and afterbody, is welded using argon gas protection weldering；Closed and
Small space uses manual electric arc welding method；The big welding for closing up seam should first weld the coverboard abutment joint between total or segmentation,
Its interstructural butt weld is welded again, then the angle welding of welding structure and coverboard；Fillet welding in the vertical position is first welded, welds flat fillet weld afterwards；Manual welding
When to longer weld seam should use point in symmetrical backstep sequence；It is big close up weld seam assembling inspection declaration it is qualified after, entered in 20 hours
Row welding.
Above-described embodiment is merely illustrative of the technical solution of the present invention, rather than design and protection domain progress to the present invention
Limit, one of ordinary skill in the art is modified by technical scheme or equivalent substitution, without departing from technology
The objective and scope of scheme, it all should cover in scope of the presently claimed invention.
