摘要：

The paper focuses on the possibility of HPDC molds restoration for aluminium casting by laser and MAG weld cladding with a welding wire of the same grade like the base material. A chemical analysis of the weld deposits showed a decrease in the content of some elements in the MAG deposit due to the higher thermal input to the weld bath. The lower heat input of laser welding has resulted in a higher incidence of fusion defects lack between the weld deposit and the base material. Thermal conditions during welding affected hardness of weld deposits and their abrasive resistance as well. The resistance of materials against dissolution when immersed in AlSi8Cu3 alloy was similar for both deposits and the base metal.
