Development of a new laser beam welding technique

Application of laser beam technology offers several advantages in the construction of ships and other marine structures as compared to the arc welding method used traditionally. Laser beam welding (LBW) allows failure-free and fine grained welded joints with more favorable mechanical and technological characteristics and at the same time metals melting at high temperature are also weldable. Microscopic cracks are reduced and smooth joint surfaces are obtained in addition to enable heat-sensitive construction units as well as transparent materials that can be welded. Improvement of beam quality, rise of efficient, and the increase of the maximum laser beam performance will make laser welding and cutting of thick sheet metals attractive and advantageous in shipbuilding and marine engineering. Moreover, laser welding method possesses many advantages in material processing and is regarded as the wear-free multi-tool of the century, providing improved welding results
