A connection structure for connecting elements of a frame, in which at least one first tubular element (16) is welded to a second tubular element (18), comprises a core (32) made of a material that is injectable in fluid form and is able to solidify expanding so as to adhere to appropriate surfaces for containing the material which belong to the tubular elements (16, 18). The connection structure is made by means of a process which comprises a step in which, inside the first tubular element (16) and at its end adjacent to the second element (18) to be joined, a material (34) in fluid form is introduced, and a step in which the material (34) solidifies, thus generating the core (32), which is rigid and adheres to the first tubular element (16) and to the second element (18). |
