Problems of narrow gaps welding of special engineering constructions

The prospects and main problems of narrow gaps welding technology application for armored vehicle frames are considered. In order to apply the narrow gaps welding successfully for high-duty products made of highstrength steel, different welding options can be used, however it is necessary to carry out the research of welding technologies. The importance of working out methods and means for a welding process visual control, including synthetic vision systems is pointed out.
