Process consisting of a series of successive stages in which the first consists in carrying out a pickling operation, using appropriate means, on the surfaces of the base of the container in question, a plate of identical shape and greater thickness of material which is a great diffuser of heat and another plate made from a ferritic material, in order, once these are clean and degreased, to next place them so that the material which is a great diffuser of heat rests on the bottom of the container and on said material lies the ferritic material, the next stage then involving subjecting the assembly to heating in a furnace or tunnel to a temperature dependent on the characteristics of the materials, dimensions and shape in order, once the appropriate temperature has been achieved, to move on to a further stage involving pressing of the assembly, in an instantaneous manner, so that the impact forms, on the contacting surfaces, a molecular integration of the different materials which form a whole which cannot be separated and which cannot be deformed under any type of conditions to which this base may be subjected.
