大型整体式核能发电机定子机座焊接制造工艺技术

Welding Manufacture Technology of Stator Frame of Monolithic Nuclear Power Generator

中国核电经过几十年来的不断发展和积累,目前国内投运核电机组49台,总装机容量5 103万千瓦,为世界之最。本文分析大型整体式定子机座的焊接结构特点,依据国际和国内现行标准,通过焊接制造工艺技术的进步和创新,顺利完成了核电定子机座的制造,并将所取得的工艺成果推广到其它热能发电机组的焊接制造过程中。

At present, the number of nuclear power plants and the total installed capacity under construction has reached49 and 51,030 MW respectively which is highest in the world, after decades of continuous development and accumulation of nuclear power in China. This paper analyzes the characteristics of welding structure and difficulties in manufacturing for stator frame of monolithic nuclear power generator. According to the current international and domestic standards for welding technicians,through progress and innovation of welding manufacture technology, has nuclear power product has been successfully manufactured, and the technological achievements is extended to the welding manufacturing process of other thermal power generating plants.
