Investigations of technology of repair laser welding of exhaust flaps of jet engine made of nickel superalloy

摘要

Analysis of weldability of nickel superalloys was carried out. Course of investigations concerning working out of technological specifications of automatic repair welding of cracks of exhaust flaps of the MIG 29 jet aircraft engine with use of the high-power diode laser was described. On the basis of visual, liquid-penetrant, and metallographic inspections, the high quality of repair welds was pointed out.
