Simulation of the Impact of a Submerged Jet with a Shield During Metal Welding for Use in the Arctic

The Arctic has a unique resource potential. Many countries around the world are ready to explore this territory for mineral exploration. This circumpolar region has been covered with many summer ice for a long time. Recently, due to global warming, the amount of ice in the Arctic has decreased significantly, but still, it is pretty enough to make it difficult for navigation. Delivery of extracted minerals in this region is possible only by sea transport. For navigation in the Arctic, icebreakers or ice-class vessels are required. In the manufacture of such ships, welds are most often used. For the seams not to oxidize during welding, it is necessary to carry out this process by blowing the seam with inert gas, for example, carbon dioxide. The method of selecting the parameters of a gas jet is very complex. Our work's theme is the impact of a submerged jet with a shield during metal welding for Arctic use. We have created a mathematical model that simulates various operation modes and chooses the optimal one.
