<P>PROBLEM TO BE SOLVED: To provide a system and a method of dual laser beam welding of a first and a second filler metal. <P>SOLUTION: The system and method for laser beam welding at least two adjacent superalloy components 102, 104 involves simultaneous formation of a base weld 110 with a cap weld 112. A shim 506 is inserted between the components 102, 104, which may be formed with a groove 105 along the joint surface 114. A filler wire 504 is fed to a location over the surface 114 or within the groove 105. A beam splitter supplies first and second laser beams 508, 510 that are irradiated at focal points 512, 514 separated by a predetermined distance 509. The first laser beam 508 is used to form a base weld 110 with the first filler metal between the components 102, 104, and the second laser beam 510 is used to form the cap weld 112 with the second filler metal on top of the base weld 110. <P>COPYRIGHT: (C)2011,JPO&INPIT |
