Purpose: of this paper: work out laser welding repair technology of cracked MIG 29 jet engine inner flaps made of cast nickel superalloy ŻS-3DK(ЖС-3ДК, Russian designation). Design/methodology/approach: The study were based on the analysis of laser HPDL powder INCONEL 625 welding of nickel superalloy using wide range of welding parameters to provide highest quality repair welds. Findings: Study of automatic welding technologies GTA, PTA and laser HPDL has shown that just laser welding can provide high quality repair welds. In order to establish the properties of welded joints repair cracks in the inner flap HPDL laser, studied the hardness, mechanical properties and erosive wear resistance. Research limitations/implications: It was found that only laser HPDL welding can provide high quality repair welds. Practical implications: The technology can be applied for repair cracked MIG 29 jet engine inner flaps. Originality/value: Repairing cracked MIG 29 jet engine inner flaps.
