description: The aim of this work is to study the possibility of using additive fabrications for filling hollow preforms with foam. To achieve this goal, it is necessary to solve the following tasks: 1. Choose a powder composition for subsequent foaming. For the study, the powder composition Al + TiH2 was selected. Based on previous experiments, such type of composition was in a foamed state during heating for the longest time; 2. Get a melting electrode for surfacing. To obtain the electrode, the method of hot extrusion was used and subsequent rolling at a temperature of 400 â; 3. Conduct surfacing of the obtained electrode by the TIG method in single and multi-pass modes; 4. To analyze the porosity in the obtained samples. During the work, the composition was selected and samples of the surfacing rod of composition Al + TiN2 were obtained, experiments were carried out on electric arc welding with a non-consumable electrode in argon, as a result of which surfacing beads were obtained after one pass and after several passes along the same path. After analyzing the structures of the three samples, we can conclude that the creation of a porous material using manual surfacing with a non-consumable TIG electrode is possible. The results show that a decrease in electric current power allows for a more uniform distribution of pores in the material.
