  • Non-destructive dimensional and flaw inspection of thin wall tube weldments
    Patent number: 5108693
    Abstract: Nuclear fuel cladding tube end plug welds are ultrasonically scanned to develop data indicative of weld thickness, weld penetration, and the existence and size of any included feature, such as pores. A computer analyzes the data to determine critical weld characteristics which are then tested against established quality assurance standards to see if the end plug weld is acceptable, all on an automated production line basis.
    Type: Grant
    Filed: September 28, 1988
    Date of Patent: April 28, 1992
