摘要：
The nature of formation of hot (crystallization) cracks in the weld metal of aluminum alloy welded joints is considered. The effect of the composition and structure of both the main metal and the weld metal on their susceptibility to the formation of hot cracks during welding is demonstrated. In order to improve resistance to hot-cracking, it is necessary to diminish the dendrite structure of the weld metal and to eliminate strongly liquating components and impurities.
