The development and application of adaptive pulse-arc welding methods for construction and repair of pipelines

The issues of the development of adaptive pulsearc welding methods for construction and repair of the main pipelines are considered in this work. Welding methods are developed on the basis of examination of melting kinetics and transfer of some electrode metal. These methods allow ensuring a defect-free formation of root, filling and facing seams of welding combination in different space positions.
