Lasers that can weld thick metal plates
The DIOMAR joint project is developing new laser welding processes in shipbuilding based on high-power lasers. This is expected to make the welding of thick metal plates more efficient and cheaper.

Costs and efficiency leave a lot to be desired when it comes to joining maritime steel components: the frequently used submerged arc welding is relatively slow and warps the workpieces, while laser-arc hybrid welding is less flexible and, especially in terms of edge preparation, labor-intensive. Especially with large steel plate thicknesses (12 to 30 mm), no method has prevailed against submerged arc welding. To come up with an alternative, the
