Description

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 therein and support technology, during the chief engineer of welding and cost respectively accounts for hull Build chief engineer time and the 30%-40% of cost, the quality of solder technology be reflection hull construction quality good or not important indicator. Therefore, research and development mechanization, the efficient welding technology of automatization be not only enterprise improve shipbuilding quality, improve production efficiency, Reduce construction cost, the effective way of shortening shipbuilding period, and be that the Modern Shipbuilding Mode realizing the proposition of boats and ships head office 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.
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 height Effect, the modern ships efficient welding technology of energy-saving and environmental protection.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
(1) groove is prepared: employing edge planer and carbon arc air gouging are to prepare groove, for the compressed air pressure of carbon arc air gouging For 0.2-0.9Mpa；
(2) groove processes: conscientiously check before weldering whether groove size and assembling quality meet relevant requirement；In groove and slope Positive and negative in the mouth each 40mm of both sides of edges and end face remove water stain, greasy dirt, rust, dross and the viscous carbon of carbon plane residual；
(3) welding: jigsaw district uses double-wire MAG welding solder technology；Little assembling district uses CO2The automatic fillet welding of gas shield or Semi-automatic fillet welding welding primary structural component and T-shaped component；Dress, welding integrated vertical bone erecting and welding skill is used at hull longitudinal manufacture Art；Last big closure workmanship, the inner bottom plating abutment joint of deck and double bottom uses CO2Ceramic backing weldering bottoming, Lincoln weld Capping, change greatly position in line styles such as hull stem and afterbodys, use CO2Gas shielded arc welding welds；Airtight and Small space uses manual electric arc welding method；The coverboard abutment joint always or between segmentation should be first welded in the welding closing up greatly seam, Weld its interstructural butt weld, then welding structure and the angle welding of coverboard again；First weld fillet welding in the vertical position, weld flat fillet weld afterwards；Manual welding Time longer weld seam should be used point in a symmetrical backstep sequence；Close up greatly weld seam assembling inspection declaration qualified after, entered in 18 hours Row welding.
Beneficial effects of the present invention: compared with traditional solder technology, the welding method of the present invention, welding efficiency is high, weldering Connecing deformation to be well controlled, during production practices, effect improves the welding quality of boats and ships, cost-effective, improves efficiency.
Detailed description of the invention
Below in conjunction with specific embodiment, technical scheme is elaborated.
Ship Welding technique, it is characterised in that: comprise the following steps:
(1) groove is prepared: employing edge planer and carbon arc air gouging are to prepare groove, for the compressed air pressure of carbon arc air gouging Power, generally 0.2-0.9Mpa；
(2) groove processes: conscientiously check before weldering whether groove size and assembling quality meet relevant requirement；In groove and slope Positive and negative in the mouth each 40mm of both sides of edges and end face remove water stain, greasy dirt, rust, dross and the viscous carbon of carbon plane residual；
(3) welding: jigsaw district uses double-wire MAG welding solder technology；Little assembling district uses CO2The automatic fillet welding of gas shield or Semi-automatic fillet welding welding primary structural component and T-shaped component；Dress, welding integrated vertical bone erecting and welding skill is used at hull longitudinal manufacture Art；Last big closure workmanship, the inner bottom plating abutment joint of deck and double bottom uses CO2Ceramic backing weldering bottoming, Lincoln weld Capping, change greatly position in line styles such as hull stem and afterbodys, use CO2Gas shielded arc welding welds；Airtight and Small space uses manual electric arc welding method；The coverboard abutment joint always or between segmentation should be first welded in the welding closing up greatly seam, Weld its interstructural butt weld, then welding structure and the angle welding of coverboard again；First weld fillet welding in the vertical position, weld flat fillet weld afterwards；Manual welding Time longer weld seam should be used point in a symmetrical backstep sequence；Close up greatly weld seam assembling inspection declaration qualified after, entered in 18 hours Row welding.
Above-described embodiment is only in order to illustrate technical scheme, rather than the design and protection domain to the present invention is carried out Limiting, technical scheme is modified or equivalent by those of ordinary skill in the art, without deviating from technology The objective of scheme and scope, it all should be contained in scope of the presently claimed invention.
