View Resource Corrosion of Welded Components in Marine Environments

Paper on how welding influences material properties and must be considered in terms of design and initial fabrication and any subsequent repair during the life of a vessel. Additionally, new fabrication processes are being developed such as laser and laser hybrid welding, friction stir welding of aluminium alloys and improved wet underwater repair, necessitating understanding of the corrosion...
