Patent number: 10682729Abstract: A system and method detect weld defects in real time. Cameras capture images of a weld pool as well as ripple shape and fillet geometry. A processor receives the images and communicates with a database that stores correlated potential weld defects with images of a mock weld molten pool and images of a mock weld ripple shape and fillet geometry. The processor computes an aggregate probability that a weld position corresponding to the images captured by the cameras contains a defect based on the potential defects correlated in the database.Type: GrantFiled: December 1, 2015Date of Patent: June 16, 2020Assignee: General Electric CompanyInventor: Andrew Batton Witney

Patent number: 9969000Abstract: A method of fabricating a joining preform includes the step of printing a self-fluxing joining alloy. Joining includes brazing and soldering. The self-fluxing joining alloy contains at least one of phosphorus, boron, fluorine, chlorine, or potassium. Another printing step prints a non-phosphorous joining alloy. Both printing steps are performed by an additive manufacturing or 3D printing process. The printing a self-fluxing joining alloy step may be repeated until the non-phosphorous joining alloy is substantially encapsulated by the self-fluxing joining alloy. The self-fluxing joining alloy may be a BCuP alloy, a CuP alloy, a CuSnP alloy, a CuSnNiP alloy or a CuAgP alloy. The non-phosphorous joining alloy may be a BAg alloy, a BNi alloy or a BAu alloy.Type: GrantFiled: July 8, 2015Date of Patent: May 15, 2018Assignee: General Electric CompanyInventors: Andrew Batton Witney, Jeffrey Michael Breznak
