ABSTRACT:
A method of casting a hollow bodied plate type recuperative heat exchange envelope. The heat exchange envelope comprises first and second envelope halves cast independently, then bonded together by fusion of molten metal of the second envelope half with solidified metal of the first envelope half. The first envelope half includes a lateral flange on opposite sides thereof that is confronted by the molten metal of the second envelope half to form a flange that connects envelope halves providing an increased area of contact therebetween. The flange of the second envelope half includes multiple surface areas that become fused to opposite sides of the first envelope half to form a strong connection impervious to fluid leakage.
