State and development trends of welding technologies in the aircraft industry.

摘要

Survey of perspective welding technologies used in aircraft industry is realized. These are pulsed arc welding, welding with submerged electrode, with scanning non-consumable electrode, plasma-arc welding, electron beam welding, light beam welding, laser beam welding as well as integral welding technologies providing complex automation etc. Development trends of welding technologies in a branch are revealed. They take into consideration technical, economical and ecological requirements and provide high aircraft production level.
