Abstract
A high power resistor grid assembly formed of a plurality of stainless steel resistor U-shaped elements arranged in a substantially parallel relationship welded together in a continuous path. Each element comprising a slotted rectangular sheet in a U-shape having elongated curved embossments to prevent warpage of the element upon heating. Each U-shaped element has alternately a right and left leg offset to permit end to end attachments of elements while maintaining uniform spacing between the elements. The elements are supported by pairs of double insulated members which are affixed to the top and bottom of a frame with a floating end to permit expansion of the assembly upon heating and contraction upon cooling.
