Abstract
1,172,593. Making heat exchangers; welding by fusion. FOSTER WHEELER CORP. 6 March, 1967 [4 March, 1966], No. 10493/67. Headings B3A and B3R. In a tube-tube plate joint in which the end of the tube 16 is a close fit in an enlarged portion of a bore 14 of the plate 10, the end of the tube 16 is joined to the plate 10 by an internal weld which fully penetrates radially to eliminate the crevice between the end face of the tube and the plate and which extends axially to a point close to the surface 28 of the plate 10 to leave a small crevice surrounding the tube 16. An insert ring may be inserted between the end of the tube 16 and the plate 10. Welding is effected by a gas, e.g. argon, shielded non-consumable electrode internalwelding gun. The enlarged portion of the tube may be reamed and polished and the tube may be expanded into the enlargement. The plate 10 may be part of a header. The plate 10 may be laminated and have a 0À12% C steel layer 13 on a body of 0À35% C steel, the tube being of 0À25% C steel.
