Abstract
Technological process of flash-butt welding of dispersion-hardened copper alloy AL-25 (C 15725) with a forced joint formation is considered. Data of metallographic and X-ray spectral microanalysis of microstructure and results of mechanical tests of welded joints are given.
Keywords: flash-butt welding, upsetting force, time of welding, dispersion-hardened copper alloy, recrystallization, flash, microstructure
