Pulsed-arc welding is characterized by a periodical changing in arc power and, due to its features, allows solving complex
technological problems while creating unique structures, increasing efficiency of welding processes while maintaining a
high level of physical and mechanical properties of welded joints. There are many manufacturers of welding equipment, that
introduced the idea of using pulsed welding in their production, but data on the impact of pulsed-arc welding on the parameters
of the welds differ. For the successful application of pulsed-arc welding in modern production, it became necessary to study
the influence of pulsed-arc welding conditions on the parameters of welds and HAZ as compared to stationary welding using
burning arc, made of low-alloy welding materials. 20 Ref., 7 Fig.
