Abstract
A method for welding and repairing cracks in metal parts is provided by subjecting the metal parts to be welded to friction stir welding and the cracks to be repaired to friction stir processing under conditions sufficient to provide a weld joint or crack repair having a preselected property or set of properties based upon the intended use of the weldment.
Claims11
A method for welding metal parts and repairing cracks in metal parts by subjecting the faying surfaces of the metal parts to be welded to FSW and the cracks to be repaired to FSP under conditions sufficient to provide a weld joint or crack repair having a preselected property or set of properties based on the intended use of the weldment.
A method for welding two pieces of metal to produce a weld joint having a specific property or set of properties chosen for an intended application, the method comprising:
- obtaining a data base of weld properties for weld joints formed by FSW under a plurality of conditions and from various metal compositions;
- correlating the weld conditions and metal compositions to the weld properties;
- selecting weld conditions from the data base that will produce a weld joint having the property or set of properties best suited to the intended application;
- subjecting the work pieces to FSW under the conditions selected.
