Analysis of modern tendencies in digitalization of economics prove the increasing interest of industrial enterprises towards new digital manufacturing technologies. Industrial laser technologies are developing really fast in various branches of industry. Perspectives of hybrid laser welding industrial application particularly in shipbuilding are rather interesting. Introduction of hybrid laser arc welding in shipbuilding increases strongly economic efficiency of the production process. Each project needs preliminary assessment. Feasibility study of replacing the automatic welding equipment by modern hybrid laser arc welding technology at a shipbuilding yard shows its relevance and importance.

Modern shipbuilding yards apply traditional aluminum alloys in production of high-speed vessels, ships with dynamic principles of support, other small vessels and vessel constructions. These alloys provide the low weight for the construction, but have definite disadvantages, which could be improved by application of the new generation Al-Sc-alloy with low concentration of scandium. The developed technology allows to increase durability and to improve other mechanical characteristics, decrease the vessels’ weight, decrease operational costs, increase the operational lifecycle of the production, as well as to achieve some indirect effects. The feasibility study was held to assess the economic effect of applying the new generation Al-Sc-alloy in shipbuilding, which proves its advantages comparing to traditionally used Al-alloys.
