| Summary: | Title screen The article is devoted to studying the influence of wire feed rate on the hardness of the welded layer during the restoration of electric motor shafts. The authors analyse the importance of optimal hardness to ensure the durability and reliability of the reconditioned parts. The paper considers various factors affecting the hardness of the welded layer, such as type of welding wire (AWS A5.18 ER70S-6, OK Tubrodur 35 G M, AWS A5.28 ER80S-G); cladding modes (feed rate, current, voltage); properties of the welded clad metal (fusion with the base, tendency to crack formation). Based on the conducted experiments, the optimal welding modes for each of the studied wires and the corresponding hardness values were determined. The obtained results allow us to conclude that the wire feed rate is one of the key parameters affecting the hardness of the welded layer Текстовый файл |
