Applications of laser welding in the shipbuilding industry
J. Klæstrup Kristensen, The Technical University of Denmark (DTU), Denmark
Laser welding, especially hybrid MAG-laser welding, shows great potential in the welding of structural steels in the shipbuilding industry. Advantageous properties include low distortion, high welding speed and easy automation. The shipbuilding industry has been one of the first to introduce high power laser and laser-hybrid welding for structural applications, with reducing distortion being the major motivation. However, many challenges had to be dealt with before laser welding processes could be introduced on an industrial scale. Today, laser-based welding is used quite extensively in European ...
