A brazing process and plate assembly are disclosed. The brazing process includes positioning a braze foil on a first workpiece, then securing the braze foil to the first workpiece to form a brazable component, then positioning a second workpiece proximal to the brazable component, and then brazing the second workpiece to the brazable component. Additionally or alternatively, the brazing process includes positioning the braze foil on a tube, then securing the braze foil to the tube to form a brazable tube, then positioning a plate of a plate assembly proximal to the brazable tube, and then brazing the plate to the brazable tube. The plate assembly includes a plate and a tube brazed to the plate by a braze foil secured to the tube.

1. A brazing process, comprising: positioning a braze foil on a first workpiece; thensecuring the braze foil to the first workpiece to form a brazable component; thenpositioning a second workpiece proximal to the brazable component; and thenbrazing the second workpiece to the brazable component;wherein the securing is by tack-welding followed by heating, the heating being between 1,300° F. and 2,200° F., at a temperature below the braze temperature of the brazable component, and for a period of between about 1 minute to about 30 minutes. 2. The brazing process of claim 1, wherein the securing is in a furnace, the furnace having a temperature within 200° F. of the braze temperature for the braze foil. 3. The brazing process of claim 1, further comprising cutting the braze foil to a predetermined length prior to the positioning of the braze foil. 4. The brazing process of claim 1, wherein the brazing is for a brazing duration, the brazing duration being between about 1 minute and about 30 minutes. 5. The brazing process of claim 1, wherein the brazable component is a brazable tube. 6. The brazing process of claim 1, comprising installing the brazable component into a plate assembly. 7. The brazing process of claim 6, wherein the installing includes mechanical locking of the brazable component into the plate assembly. 8. The brazing process of claim 6, wherein the plate assembly is arranged and disposed to contain a fluid. 9. The brazing process of claim 8, wherein the plate assembly is devoid of fluid leaks. 10. The brazing process of claim 8, comprising inspecting the plate assembly for fluid leaks. 11. A brazing process, comprising: positioning a braze foil on a tube; thensecuring the braze foil to the tube to form a brazable tube; thenpositioning a plate of a plate assembly proximal to the brazable tube; and thenbrazing the plate to the brazable tube;wherein the securing is by tack-welding followed by heating, the heating being between 1,300° F. and 2,200° F., at a temperature below the braze temperature of the brazable component, and for a period of between about 1 minute to about 30 minutes.
