The powerful laser sintering experiment is performed on the foundry material GH4169 of an aircraft engine blade by using FGH95 which is one of nickel-based metal powder material. By changing the technology parameters such as pump current, defocusing distance, scanning speed and scanning line spacing in the laser sintering process, the effect on the forming quality of fusion zone of the sintered specimens is studied. It has been found that the foundry material GH4169 can achieve a good metallurgical bonding with nickel-based metal powder material FGH95. When the pump current is 300 A, the defocusing distance is 8 mm, the scanning speed is 180 mm/min, the scanning line spacing is 1.0 mm, and the fusion zone in laser cladding has a better forming quality.
