Welding consumables: status and tendencies of development

摘要

Data are presented on modern production and consumption of steel in different regions of the world. Advance of mechanical engineering, shipbuilding, construction and other industries will require reduction of the weight of welded structures, improvement of their reliability and fatigue life, and lowering of power consumption in welding operations. The above problems can be solved by using high-strength low-alloyed (HSLA) steels in critical structures. Data are given on the status of metallurgy and technology of welding HSLA steels in Russia and Ukraine. problems of welding HSLA steels and tendencies of their development are analysed, and areas of further research are outlined. Level of development of general-purpose consumables is considered and recommendations on their improvement are given.
