Abstract
The laser beam welding of a spacer grid assembly is accomplished by dividing a laser beam (21) into at least two beam segments (37). These beam segments (37) are then routed around the mixing vanes (31) and focused below the vanes (31). The focus and coincidence (34) of the beam segments (37) may be moved down along the intersection to provide an elongated smaller diameter weld. The spacer grid assembly of the present invention has an improved Departure from Nucleate Boiling performance, increased strength against buckling, and a reduced detrimental effect on the coolant flow.
