For joining the 5XXX alloys to themselves, the correct filler is 5554 for welding 5154 or 5454. For welding 5052, 5356 should be used.
The use of aluminium in naval shipbuilding exists in two forms; first there is the aluminium-steel ship, where in the case, the superstructure is made from aluminium intended for topside weight saving, and the hull made from steel. Then there is the all-aluminium ship, with the purpose of achieving a considerable overall reduction in weight. Building ProcessShipbuildingEnglishA ship consists of complicated curved surface, so we need to bend the steel plate because it is a plane. Pushing it with a press machine or heating the surface by a gas burner, we bend it carefully little by little to match the model. so the painting is a very important process on shipbuilding. Launching.
Block Installation and Assembly. We install and joint assembled blocks by right order on a building berth by a crane, and assemble them in the form of the final ship. We must fix them at the correct position because the shape of the ship is warped if the fixed position of the block is wrong.
