Grid welding fixture for a spacer grid

A grid welding fixture for a spacer grid, comprising:

• a. a base plate having a plurality of through holes that correspond to the intersections of strips in the spacer grid to be welded;
• b. a sub-plate adapted to be received on said base plate, said sub-plate being designed to provide positional location of the grid strips of the spacer grid for welding;
• c. a top fixture plate having a plurality of through holes that conespond to the intersections of strips in the spacer grid to be welded, said top fixture plate being designed to be received above said base plate on the spacer grid to be welded;
• d. a side plate hingedly attached to each side of said top fixture plate so as to be movable between a first up position and a second down position and adapted to be attached to said base plate when in said second position;
• and
• e. a pressure pad mounted in a spring loaded fashion on each of said side plates such that said pressure pads contact the spacer grid to be welded when said side plates are in said second position.
