“…Pulsed-arc welding (PAW) is qualitatively different from traditional welding in shielding gases [1][2][3][4]. This is predetermined by expanded capabilities of PAW in affecting the processes of melting and transfer of the electrode metal, formation of the structure in the weld and HAZ metal of welded joint, regulating the weld shape, penetration depth, etc.…”

The use of modern pulsed-arc welding technologies allows a significant improvement of the quality of welded joints. However, a large number of possible welding modes hinder the development and implementation of pulse technologies in modern production. This is associated with the fact that in pulsed-arc welding at least four independently variable parameters exist, which in totality requires a large number of experiments to determine their impact. To optimize the number of experiments in this study, the experimental calculation Taguchi algorithm for the process of pulsating arc welding using a high alloy welding material was implemented. The quantitative contribution of each variable welding parameter in the formation of the penetration depth is shown. The optimal welding modes were proposed, providing a set penetration depth. 15 Ref., 6 Tables, 4 Figures.

Industrial development continues to present challenges for manufacturers. One of them is additive manufacturing (AM) with metallic materials. One promising solution is wire arc additive manufacturing (WAAM). Currently, WAAM is a more promising tool for developers, firstly due to the simplicity of its realization and secondly for its cost-effectiveness. Building materials are represented by welding wires, so the deposition rate is favorable. A pulse power source is commonly used in this scheme of realization. Much less attention has been paid to the optimization of the power source working regime, i.e., welding mode. Indeed, the power determines the whole process of WAAM. Therefore, in the present work, an attempt has been made to perform a scientifically based design for the optimal welding mode. The austenitic welding wire was chosen to eliminate phase-transition effects in the solid state of the deposited metal. As a result of the investigation, the advantages of the designed welding mode for WAAM application are made clear. Successful efforts have been made to optimize welding modes for WAAM applications. This study is important for manufacturers as well as engineers and scientists.

У роботі проведено порівняльні експериментальні дослідження впливу параметрів імпульсного дугового натоплювання на геометричні розміри натоплених валиків і структуру натопленого металу системи леґування Fe-C-Cr-Ti-Mn-Si. За еталон взято зразки, натоплені на таких самих режимах, але без застосування імпульсних технологій. Дослідження виконували із використанням напівавтомату Fronius TPS 400i зі власним джерелом живлення та універсальної натоплювальної установки У-653, укомплектованої джерелом живлення ВДУ-506. Експериментально визначено, що використання імпульсних режимів натоплювання призводить до зміни мікроструктурного стану натопленого металу і до підвищення його твердості в середньому на 4-5 одиниць за шкалою HRC, порі-
