A method of manufacturing a thermocouple (1) including an electrically conducting body fixable in use to a burner of a cooking range and a hot junction (3) consisting of a tip made of a first conducting metal alloy, integrally carried by the body, and of a conducting element (5) made of a second metal alloy, accommodated and welded within the tip, wherein the body (2) is made from a flat sheet which is worked so as to form a tube length (12) therewith, a side wall (13) of which is less than 1 mm thick, and wherein at least one annular axial abutment (15) is formed on the side wall and, at a predetermined axial distance therefrom, at least one annular groove (16) is formed, obtained by plastically deforming the side wall towards the interior of the tube length; the hot junction (3) is then axially inserted into the tube length and welded to a first end (21) thereof. |
