    Abstract: Aiming at the phenomenon that the exothermic fusion welding point had high defect rate in power transformation engineering,this paper analyzed the causes from the aspects of welding mould, welding material and welding technology and enacted the corresponding measures for the main terminals. After the generalized implementation in the new construction of Jiujiang 500 kV power transformation engineering,this correlation method and measures reduce the defect rate of exothermic fusion welding point.
    Key words: exothermic fusion welding; power transformation engineering; grounding grid; defect rate
