Description

A kind of Ship Welding technique
Technical field
The present invention relates to a kind of welding procedure, be specifically related to the High Efficiency Welding Process in a kind of shipbuilding.
Background technology
In the construction of boats and ships, welding is key wherein and support technology, and during the chief engineer of welding and when cost respectively accounts for the chief engineer of hull construction and the 30%-40% of cost, the quality of solder technology is the important indicator of reflection hull construction quality good or not.Therefore, the efficient welding technology of research and development mechanization, automation is not only enterprise's raising shipbuilding quality, the effective way of enhance productivity, reduce construction cost, shortening shipbuilding period, and is the technological progress growth point realizing the Modern Shipbuilding Mode conversion that boats and ships parent company proposes.High speed and high efficiency welding are the developing direction of modern welding, are the only ways realizing modernization welding.
Summary 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, to realize setting up modern ships efficient welding technology that is efficient, energy-saving and environmental protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
(1) groove is prepared: adopt edge planer and carbon arc air gouging to prepare groove, the compressed air pressure for carbon arc air gouging is 0.6 ~ 0.8Mpa;
(2) groove process: conscientiously check before weldering whether groove size and assembly quality meet relevant requirements; Positive and negative in groove and in each 35mm in bevelled edge both sides and end face remove water stain, greasy dirt, iron rust, dross and carbon and dig the sticky carbon remained;
(3) weld: jigsaw district adopts double-wire MAG welding solder technology; Little assembling district adopts CO 2primary structural component and T-shaped component are welded in the automatic fillet welding of gas shield or semi-automatic fillet welding; Hull longitudinal manufacture place adopts dress, welding integrated vertical bone Erection Welding Technology; Last large closure workmanship, the inner bottom plating abutment joint of deck and double bottom adopts CO 2ceramic backing weldering bottoming, Lincoln weld capping, change greatly position in line styles such as hull stem and afterbodys, adopt CO 2gas shielded arc welding welds; Manual electric arc welding method is adopted at airtight and small space; The welding of closing up greatly seam first should weld the coverboard abutment joint between total or segmentation, then welds its interstructural butt weld, the then angle welding of welding structure and coverboard; First weld fillet welding in the vertical position, rear weldering flat fillet weld; Symmetrical backstep sequence in should adopting point longer weld seam during manual welding; Close up greatly weld seam assembling inspection declaration qualified after, welded in 20 hours.
Beneficial effect of the present invention: compared with traditional solder technology, welding method of the present invention, welding efficiency is high, and welding deformation is well controlled, and in production practices process, effect improves the welding quality of boats and ships, cost-saving, raises the efficiency.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme of the present invention is elaborated.
A kind of Ship Welding technique, is characterized in that: comprise the following steps:
(1) groove is prepared: adopt edge planer and carbon arc air gouging to prepare groove, for the compressed air pressure of carbon arc air gouging, be generally 0.6 ~ 0.8Mpa;
(2) groove process: conscientiously check before weldering whether groove size and assembly quality meet relevant requirements; Positive and negative in groove and in each 35mm in bevelled edge both sides and end face remove water stain, greasy dirt, iron rust, dross and carbon and dig the sticky carbon remained;
(3) weld: jigsaw district adopts double-wire MAG welding solder technology; Little assembling district adopts CO 2primary structural component and T-shaped component are welded in the automatic fillet welding of gas shield or semi-automatic fillet welding; Hull longitudinal manufacture place adopts dress, welding integrated vertical bone Erection Welding Technology; Last large closure workmanship, the inner bottom plating abutment joint of deck and double bottom adopts CO 2ceramic backing weldering bottoming, Lincoln weld capping, change greatly position in line styles such as hull stem and afterbodys, adopt CO 2gas shielded arc welding welds; Manual electric arc welding method is adopted at airtight and small space; The welding of closing up greatly seam first should weld the coverboard abutment joint between total or segmentation, then welds its interstructural butt weld, the then angle welding of welding structure and coverboard; First weld fillet welding in the vertical position, rear weldering flat fillet weld; Symmetrical backstep sequence in should adopting point longer weld seam during manual welding; Close up greatly weld seam assembling inspection declaration qualified after, welded in 20 hours.
Above-described embodiment is only in order to illustrate technical scheme of the present invention; but not design of the present invention and protection domain are limited; those of ordinary skill in the art modifies to technical scheme of the present invention or equivalent replacement; and not departing from aim and the scope of technical scheme, it all should be encompassed in right of the present invention.
