Improving the service properties of metal structures working in the conditionsof low climatic temperatures by methods of adaptive pulsed-are welding

摘要

Experimental results confirm that the application of adaptive pulsed-arc welding with regulated heat input to welded material refines the structure of the metal, lowers the degree of softening of the fusion zone of the welded joint and greatly increases the mechanical properties of the welded joints, including structures working at low temperatures.
