The relationship between the microstructure, constitution and phase of MGH956 superalloy joint TLP bonded with KNi9 interlayer and the bonding process is analyzed. The forming mechanism of defects in welds is explained and the process parameters are optimized. The research results show that the integrated TLP bonded joints are obtained when bonding temperature T is 1 240℃ and holding time t is 480min.
