岭澳核电汽轮发电机外机座冷却器罩装焊工艺

Study on assembly and welding process for base cooler cover of Ling'ao nuclear power turbine generator

东方电机股份有限公司为确保岭澳核电发电机外机座关键部件冷却器罩的合格生产,从合同要求出发,结合企业实际情况,低成本、高质量地完成了冷却器罩制造。冷却器罩尺寸大,精度要求高,按合同要求一次成型难度大。通过几种备料成型方案的对比,最终选择较为有效且经济的方案。同时制定合理的装焊工艺,确保成型尺寸,最终控制了焊接变形,确保合同尺寸要求。对与国外企业合作生产发电机产品在备料装焊工艺创新方面有一定的指导意义。

In order to ensure the base cooler cover manufactured with high quality,which was the key components of Ling Ao nuclear power generator base made in Dongfang Electrical Machinery Co.,Ltd.,cooler cover would be manufactured with high quality and expensively according to demand of contract ,cooler cover was large size and high precision required.Forming of cooler cover at one time was diffficult.Through comparing of several projects,the final choice of forming programs was more effective and economical. Making a process of assembly and welding,we ensured shape size aand decreased welding distortion.It would be certain significance that generators were co-product with foreign enterprises in process of preparation and assembly.
