Abstract
The article describes opportunity of improvement of physical-mechanical properties of welded joint made of different strength grade pipeline steels (Steel 20 of K42 strength grade and 16ГС – K52) by applying vibration during the welding cycle. It’s shown that maximal positive effect is achieved by vibration frequency approximating to natural-vibration frequency of welded construction.
