One of the important goals in the manufacture of aluminum alloy high-speed wire is to reach the design speed. In order to achieve this goal, the lighter the weight of the ship, the faster the ship, the lower the fuel consumption, and the density of aluminum alloy is only 1/3 that of steel, which can greatly reduce the weight of the ship. This characteristic makes aluminum alloy very suitable as a material for the construction of high-speed ships. BelowOfficial BoatManufacturers share the weld design of aluminum alloy high-speed ship.

In the construction, in addition to strictly controlling the weight of the boarding material, the aluminum alloy ship can also use welding design and as far as possible intermittent welding to control welding deformation, and can also reduce the weight of the empty ship. However, the official boat manufacturer believes that because intermittent welds are not suitable for high stress or special areas, the official boat manufacturer believes that the following welding design requirements must also be remembered:

　　Official BoatManufacturers share welding design requirements for high-speed ship specifications.

1. The connection welding required by the specification for double-sided continuous welding is as follows: medium ship material and flat keel, mechanical base and support structure, perimeter of mipliometer rolling mill structure, all structures of steering gear, bottom and first structure in impact area, support and end of splint, column, cross material and plate, above propeller, radius area at least 1.5 times of propeller diameter. Official Boat

2. The height of the weld leg is not only calculated according to the welding coefficient in the specification, no matter what kind of welding form and welding method is used, the weld leg of the fillet weld must be 3mm, but it does not have to exceed 1.5 times the thickness of the book component. The height of the leg of intermittent welding is generally not more than 7mm.

3. In intermittent welding, the length of the elbow toe tip is not less than the height of the connecting aggregate, which should be at least 75mm. At the end of the profile, especially the end cutter, the length of the gun angle should not be the height of the profile or less than the length of the bevel. The vertical intersection of various openings, cut ends and mutually perpendicular connecting members shall be at least 75mm. The continuous length of intermittent welds is usually not less than 15 times the plate thickness or 75mm.

Official boat manufacturers talk about experience supplementary requirements

On the premise of meeting the requirements of the construction specification, the shipyard will supplement according to the requirements of the design company, many years of production experience and the information feedback of the operating ship owner.

1. Anti-collision of broadside The broadside must be welded continuously on both sides corresponding to the longitudinal bones in the hull. Official Boat

2. The fillet welding of all parts of the seawater ballast tank must be double-sided continuous welding.

3. The lower deck aggregate or girder corresponding to the upper bulkhead shall be welded continuously on both sides.

4. Mooring equipment, cranes, ships, columns, masts connected to the hull structure and nearby components should be double-sided continuous welding.

5. The area where the condensate can be attached for a long time shall be double-sided continuous welding. Official Boat

6. All corner arcs and bevel chamfers need double-sided continuous welding.

7. The elbow plate welding is double-sided continuous welding;

8. The perimeter structure of the deck or bulkhead opening shall be double-sided continuous welding.
