Abstract
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 yards. This chapter reviews the advantages and challenges associated with laser welding, the mechanical properties that can be achieved, and its development and application in the shipbuilding industry.
