Abstract
The article describes opportunity to improve mechanical properties of welded joints made of steel 09Г2С applying vibration during the welding cycle. The methodology of experimental studies with a description of the oscillation superposition scheme with different frequencies of treatment during welding is carried out. The results of metallographic study and impact strength tests of welded samples are presented.
