Abstract In this paper, the types and causes of defects in laser cladding layer are summarized, and the effects of cladding technology parameters such as laser power, scanning speed, lap rate and protective gas flow on the occurrence and suppression of defects are analyzed, so as to improve the surface performance of parts and prolong the service life.At last, it is pointed out that a perfect process database should be established in the current study of laser cladding defects and the prospect of using modern means such as big data to monitor the molten pool and collect and analyze the process data is presented.

Key words： laser cladding the defect process parameters protection gas flow
