Description

The TIG process form welding zircaloy tube-end plug to fabricate UO2 pellet fuel rods is presented. The zircaloy tube is used as weld by welding zircaloy end-plugs inserted into ends. The technical aspects of this welding process, necessary equipment, and weld properties are discussed. The main problems involved with this type of weld and the nondestructive and destructive weld quality controls are emphasized. (Author)

Abstract (Portuguese)

O processo de soldagem TIG e largamente utilizado na fabricacao de varetas combustiveis de reatores dos tipos PWR e BWR. A vareta combustivel e constituida de pastilhas de UO2 e revestimento de tubo de zircaloy, selado em ambas extremidades por soldas circunferenciais em tampoes tambem de zircaloy. Discutem-se os aspectos tecnicos do processo de soldagem, os equipamento necessarios e propriedades das soldas. Enfatizam-se os principais problemas envolvidos com este tipo de solda, e os controles de qualidade destrutivos e nao destrutivos. (Autor)
