Unified Institute for Physical-Engineering Problems of the North, Siberian Division of the Russian Academy of Sciences, Yakutsk, Russia

Abstract
Problems associated with operation and repair of industrial facilities and metal structures under the Russian North conditions are considered. Areas of basic and applied research conducted by Yakut scientists with a purpose to develop new materials, welding processes and study behaviour of welded structures during operation are described. Promising lines for further research are presented.
Keywords: welded structures, evaluation of state, life, extreme conditions, structural materials, mechanical properties, structure, cracks, materials science problems
