DownloadenquiryFriction stir welding (FSW) is a solid-state joining process that very suitable for both small and large shipbuilding projects because it can help you reduce assembly time or speed up the construction process. FSW is a solution to the many problems companies have been facing with welding aluminum such as high distortion and poor weld quality. The flatness of the FSW panels, free from distortions and buckling will ensure the highest efficiency during fabrication and this will save man-hours/cost and improve quality.
The marine industry has made a rapid conversion to aluminum friction stir extrusions and was one of the first industries to utilize friction stir welding for commercial applications. FSW, in the marine industry, is generally used to join multiple sheets of metal together to form large panels.
Friction stir welding principle and microstructure:
The FSW panel are applied to both the superstructure and hull of ships. The FSW panel product offered by Haomei Aluminum has been approved by all major classification societies such as DNV, CCS, BV, LR. Our highly automated FSW machine makes it possible to weld large size panels up to 15 meters in length. The aluminum alloys we use are seawater resistant and have the mechanical properties of mild steel at merely one third of the weight.
The marine aluminum panels are produced by Friction Stir Welding of large aluminium profiles, rather than the more traditional methods based on manual welding of sheet metal. The absence of melting during welding gives a modularised panel free from thermal distortions, and with a plane and smooth top surface. There is no need for after work such as grinding and brushing on friction stir welded panels. This results in a process that is cheaper overall with substantial weight reductions and an end product with a superior finish.
