摘　　要：研究了WX23Z-109(220 MW)空内冷汽轮发电机连接环焊接的主要工艺参数,探索了厚铜材焊接新工艺。比较了传统的熔化极惰性气体保护焊和脉冲熔化极惰性气体保护焊。实践证明,脉冲熔化极惰性气体保护焊的焊接质量优良。The main process parameter of WX23Z - 109 （220 MW） inner air-cooled turbo-generator phase-ring welding was studied, the new welding process of thick copper material was explored. Compared to traditional melting inert gas welding and pulse metal inert gas shielded were welding. Practive had proved that the pulse melting polar inert gas welding had good quality.
