Analytical approach for determining the surface shape of a liquid metal under laser cladding conditions

Аннотация

We propose an improvement of an analytical approach presented previously for determining the surface shape formed during laser cladding process at the goods manufacturing in additive technologies. The approach is based on the balance of pressures on the liquid metal surface, which occurs under the gravity and surface tension. A method generalization is proposed for the case of a curvilinear shape of a substrate, which allows determining the surface ge-ometry at arbitrary contact angles for single beads, vertical walls, and coatings formed by overlapping beads. The verification of the considered approach was carried out for laser cladding problems with the use of experimental data obtained by other authors.
