Study of the Process of Additive Formation of Low-Melting Materials by Means of a Low-Power Solid-State Laser

Purpose of research. Testing a method for additive formation of low-melting materials through the use of a low-power solid-state (ytterbium) laser (maximum power 50 W). A series of experiments have been carried. As a result of those experiments, the elements of shaping mode have been obtained. They ensure the shaping of products without complete melting of the construction material while preserving the shape of a rough workpiece. Thus, the possibility of using this type of equipment for shaping products from low-melting materials in an additive way has been confirmed, which is the basis for further research on other materials, as well as the additional use of a shielding atmosphere.
Methods. Methods of experiment planning and empirical data processing have been used for conducting experiments.
Results. The possibility of using a low-power laser for the set tasks has been confirmed. Values ranges of shaping modes have been obtained, which ensure the formation of products made of low-melting materials by the partial melting technique through an additive method.
Conclusion. The experimental studies have shown that a low-power solid-state laser can be applied for shaping products made of low-melting materials using an additive method. Applying the results of this study will allow further development of additive shaping of other metals (such as copper or aluminum), for which it is necessary to upgrade the equipment in terms of creating a shielding atmosphere in the melt zone, as well as increasing the laser power.
